The parakeet Brotogeris tirica feeds on and disperses the fruits of the palm Syagrus romanzoffiana in
Southeastern Brazil
Provedor de dados: 49
Autores: Sazima,Ivan.
Small psittacids remain unrecorded as dispersal agents of palm fruits in Brazil. I record here the plain parakeet (Brotogeris tirica),
an Atlantic forest endemic, feeding on and dispersing the fruits of the palm Syagrus romanzoffiana at Ubatuba, northern coast of
São Paulo, Southeastern Brazil. The birds removed the fruit and carried it away from the mother-tree in about 40% of the feeding
records. While perched on trees and shrubs of the understorey, the parakeets removed and ingested most of the mesocarp,
dropping the partly consumed fruit. As the parakeets damaged no the embryo and may feed at a distance from the mother-tree,
they act as primary dispersal agents. This is the first substantiated record of a small Neotropical psittacid as a stomatochorous...

What coatis and mongooses have in common?
Provedor de dados: 49
Autores: Sazima,Ivan.
The coatis (Procyonidae) and some species of mongooses (Herpestidae) are diurnal, small to medium-sized carnivores that live in
groups and feed opportunistically on small animals and fruits. A comparison of selected features is here presented for two coati
species (Nasua narica and N. nasua) and the banded mongoose (Mungos mungo). The former two dwell in the Neotropical region,
whereas the latter occurs in the Ethiopian realm. Both the coatis and the mongoose are apt to live near human settlements and
capitalise on food refuse. Additionally, coatis and mongooses habituate to humans, and sometimes are a nuisance. These habits,
plus their almost constant quest for food, lead these carnivores to meet other mammal types at feeders and garbage dumps and...

Whalesuckers and a spinner dolphin bonded for weeks: does host fidelity pay off?
Provedor de dados: 49
Autores: Silva-Jr,José Martins; Sazima,Ivan.
The whalesucker Remora australis (Echeneidae) is an oceanic diskfish found attached to cetaceans only and its habits are therefore
poorly known. At the Fernando de Noronha Archipelago, off North-eastern Brazil, spinner dolphins Stenella longirostris
(Delphinidae) regularly congregate in large groups in a shallow bay, which allows for underwater observations of their behaviour
and their fish associates. In the course of a broader study of this elusive diskfish, we had the opportunity to made multiple records
of two whalesucker couples (three of the fish naturally marked) attached to the same individual dolphin in two different years,
over periods of 47 and 87 days respectively. In all the sightings the whalesucker individuals of a couple were recorded...

Brazilian cleaner birds: update and brief reappraisal

Autores: Sazima,Ivan; Sazima,Cristina.
Some bird species feed on external parasites, such as ticks and flies, on the body of mammals (hosts or clients). So called cleaner
birds that occur in Brazil were reviewed recently, but gathering of significant new data indicates the need for an update and a brief
reappraisal of such association. New records raise the number of known clients for some cleaning birds. The Southern Caracara
(Caracara plancus) picks ticks on cattle, and the Black Caracara (Daptrius ater) picks ticks on capybaras. The Wattled Jacana
(Jacana jacana) picks ticks, horseflies, arthropods and organic debris on capybaras, and tick-picking on capybaras by the Shiny
Cowbird (Molothrus bonariensis) is substantiated by photographs. The Cattle Tyrant (Machetornis rixosa) deftly catches...

Free meals on long-distance cruisers: the vampire fish rides giant catfishes in the Amazon
Provedor de dados: 49
Autores: Zuanon,Jansen; Sazima,Ivan.
The trichomycterid catfishes known as candirus are renowned for their blood feeding, but information on their habits under
natural conditions is very fragmentary and generally restricted to hosts or habitats. We recorded an undescribed species of the
vandelliine genus Paracanthopoma riding the giant jau catfish, Zungaro zungaro (Pimelodidae), in the upper Amazon. The
candirus were found on the host's caudal and pectoral fins, as well as the base of the dorsal fin, with their snouts buried up to the
eyes in the tough skin of the catfish host. All of them had small amounts of partly digested blood in the distal part of the gut.
Along the host's dorsal fin base we found a few additional tiny holes, most of them healed. We suggest that Paracanthopoma feeds

Several bird species feed on a variety of external parasites and epibionts, organic debris, dead and wounded tissue, clots and
blood, and secretions from the body of other vertebrates (hosts or clients). We present an overview of so called cleaner birds from
the Neotropics based on field records, literature, and photo survey. We found that 33 bird species in 16 families practice cleaning
even if some of them do so very occasionally. The birds range from the Galápagos ground finch Geospiza fuliginosa to the
widespread black vulture Coragyps atratus. Clients mostly are large herbivores such as capybaras, deer, and livestock, but also
include medium-sized herbivores such as iguanas and tortoises, and carnivores such as boobies and seals - a few bird species...

The association of the goatfish mulloidichthys martinicus with the grunt haemulon chrysargyreum: an
example of protective mimicry

Autores: Krajewski,João Paulo; Bonaldo,Roberta Martini; Sazima,Cristina; Sazima,Ivan.
A presumed example of protective mimicry between the yellow goatfish, Mulloidichthys martinicus (Mullidae) and the
smallmouth grunt, Haemulon chrysargyreum (Haemulidae) is described from Fernando de Noronha Archipelago, NE Brazil. The
goatfish and the grunt share a similar overall shape and colour pattern. We found that these two species regularly form mixed
schools around reefs. Additionally, when chased small groups of yellow goatfish join schools of smallmouth grunts and behave
like them. The colour and shape resemblances between the two species enable their mixed schooling, and enhance the protection
against visually oriented predators for both of them. Thus, we suggest that the protective association herein reported for the
goatfish and the grunt may...

Little dragons prefer flowers to maidens: a lizard that laps nectar and pollinates trees
Provedor de dados: 49
Autores: Sazima,Ivan; Sazima,Cristina; Sazima,Marlies.
Lizards rarely visit and pollinate flowers, the few recent records being mostly restricted to island habitats. We report here on the
Noronha skink (Euprepis atlanticus) seeking nectar in the flowers of the leguminous mulungu tree (Erythrina velutina) at
Fernando de Noronha Archipelago, off northeast Brazil. The mulungu tree blooms during the dry season, and each flower secretes
copious and diluted nectar throughout the day. The Noronha skink climbs up to the inflorescences and laps the nectar accumulated
in the flowers' base. While exploiting the flowers and crawling over the inflorescences, the body parts of the skink contact the
anthers and stigmas and pollen adheres to the lizard's scales. The lizard visits inflorescences from the same and different...

Fishing behaviour by Black Caracaras (Daptrius ater) in the Amazon
Provedor de dados: 49
Autores: Olmos,Fabio; Sazima,Ivan.
The Black Caracara is a widespread raptor in the Amazonian lowlands, mostly associated to riverine habitats. This bird is
considered as a generalist scavenger that occasionally takes small prey and feeds on fruit. Here we report on Black Caracaras
foraging on live small fish caught while moving upriver in the Rio Roosevelt rapids in the Amazonas state, northwestern Brazil.
Fish were picked individually either with the bill or talons in a stretch of shallow water plenty of aquatic plants. This fishing
behaviour seems unreported and adds another feeding mode to the already diversified portfolio of foraging strategies for the
Caracarini.

The Caracarini falcons are among the most versatile birds of prey, and their variable diet includes fishes, which may be taken as
carrion. However, fishing behaviour is described for two species. Here we describe the Chimango Caracara (Milvago chimango)
fishing at an estuary in Chile, Pacific coast of South America. The caracara flew and glided close to water surface, hovering on
occasions. After such a hovering, the bird plunged and attempted to snatch a prey with its talons. If successful, the caracara carried
the fish in its talons and landed on an adjacent beach where the prey was torn apart and eaten. The 'glide-hover' technique of the
Chimango Caracara differs slightly from the fishing recorded for the closely related Yellow-headed Caracara (Milvago...

Hawksbill turtles visit moustached barbers: cleaning symbiosis between eretmochelys imbricata and
the shrimp stenopus hispidus
Provedor de dados: 49
Autores: Sazima,Ivan; Grossman,Alice; Sazima,Cristina.
This seems to be the first record of cleaning symbiosis between marine turtles and shrimps. During their foraging on the reef flat,
the turtles regularly visited and posed at the stations. The same stations were visited by a few species of reef fishes, which posed
and were cleaned by the shrimps. We suggest that cleaning symbiosis between turtles and shrimps is widespread and went
unrecognised due to the superficial resemblance between a resting turtle and a posing and cleaned one. Additionally, we submit a
putative origin for the cleaning symbiosis between marine turtles and cleaner shrimps following a few simple behavioural steps.

Paulo, southeastern Brazil. The birds inspected the mammals’ skin, both in places with and without hair. The hair was parted
with bill movements, and ticks were removed by vigorous pulling. The birds also pecked at open or healing sores, from which
they extracted small portions of blood clots and dead tissue. The capybaras appeared oblivious to the birds’ activity. Even in the
case that the cleaning behaviour is restricted to some bird individuals and populations, or places and periods, this record

Turtle riders: remoras on marine turtles in Southwest Atlantic

An overview is presented for a poorly documented relationship between reef vertebrates in Southwest Atlantic: remoras
(Echeneidae) associated with marine turtles. Two remora species (Echeneis naucrates and Remora remora) and four turtle species
(Caretta caretta, Chelonia mydas, Eretmochelys imbricata, and Dermochelys coriacea) are here recorded in symbiotic associations
in the SW Atlantic. Echeneis naucrates was recorded both on the coast and on oceanic islands, whereas R. remora was recorded
only at oceanic islands and in the open sea. The remora-turtle association is usually regarded as an instance of phoresis
(hitchhiking), albeit feeding by the fish is also involved in this symbiosis type. This association seems to be rare in SW Atlantic.

The single record of the sharksucker (Echeneis naucrates) attached to a spinner dolphin (Stenella longirostris) is based on a

demonstrates that the diskfish attached to the dolphin is the whalesucker (Remora australis), a species so far recorded on cetaceans
only. Thus, the record of S. longirostris as a host for E. naucrates is here invalidated and the value of vouched records is reiterated.
The exaggerated reliance even on refereed papers dealing with species records and checklists that lack or have dubious vouchers

Brazil. Nine reef fish species and three turtle species involved in cleaning are herein recorded. Besides our records, a summary of
the literature on this association type is presented. Postures adopted by turtles during the interaction are related to the habits of
associated fishes. Feeding associations between fishes and turtles seem a localized, albeit common, phenomenon.

We found yellowish juvenile coneys (Cephalopholis fulva) at Fernando de Noronha Archipelago, off Northeast Brazil, joining
schools of similarly sized and coloured brown chromis (Chromis multilineata) when these latter closely approach the rocky reefs.
Mingled within the mid-water hovering group of the plankton-feeding chromis, the piscivorous coney is able to approach unaware
prey - an instance of aggressive mimicry. Three out of four coney individuals hunting under such disguise were successful in their
attempts to prey on the otherwise wary rock-dwelling blenny (Malacoctenus species). This is the first instance of an epinepheline
grouper mimicking a schooling and plankton-eating damselfish model in the West Atlantic.

Fishes associated with spinner dolphins at Fernando de Noronha Archipelago, tropical Western
Atlantic: an update and overview
Provedor de dados: 83
Autores: Sazima,Ivan; Sazima,Cristina; Silva-Jr,José Martins da.
An update is presented for fish species associated with spinner dolphins at Fernando de Noronha Archipelago, tropical Western
Atlantic, providing a general view of their diversity. The associates are mostly reef-dwelling fishes that feed on the dolphin
wastes. Twelve species are habitual or occasional plankton-eaters and two species are herbivores that occasionally forage on
floating pieces of algae. One species is a strict carnivore, one species is a hitchhiker that forages on a variety of foods including
parasites and dead tissue from the dolphins, and one species is a carnivore that joins the dolphin groups to forage on schools of
small fishes or squids. We predict that the list of fish associated with spinner dolphins will expand mostly with addition...

Fallen leaves on the water-bed: diurnal camouflage of three night active fish species in an Amazonian
streamlet
Provedor de dados: 83

Resemblance to dead leaves is a well known type of camouflage recorded for several small vertebrates that dwell in the leaf and
root litter on the ground. We present here instances of such resemblance in three species of nocturnal fishes (Siluriformes and
Gymnotiformes) that spend the daytime among submersed root-tangle with leaf litter in Amazonian streams. All three species are
very difficult to spot visually, due both to their shape and colors which blend with the substrate, as well as to the heterogeneous
nature of their cover. Two species were recorded to lie on their sides, which adds to their resemblance to dead leaves. When
disturbed, one species may drift like a waterlogged leaf, whereas another moves upwards the root-tangle, exposing its fore...

Autores: Luiz,Osmar J; Sazima,Ivan; Waib,Luis F; Ferreira,Carlos Eduardo L.
The reproductive strategies of surgeonfishes of the genus Acanthurus are well known for all Atlantic species except the Monrovia
doctorfish, Acanthurus monroviae, an eastern Atlantic surgeonfish whose biology remains largely unknown. We provide here the
first account on the spawning behavior of A. monroviae, an exotic fish on rocky reefs of southeastern Brazilian coast.

Stirring, charging, and picking: hunting tactics of potamotrygonid rays in the upper Paraná River
Provedor de dados: 83
Autores: Garrone-Neto,Domingos; Sazima,Ivan.
Hunting tactics of potamotrygonid freshwater rays remain unreported under natural conditions. Three main foraging tactics of
Potamotrygon falkneri and P. motoro are described here based on underwater observations in the upper Paraná River. Both species
displayed similar behaviors. The most common tactic was to undulate the disc margins close to, or on, the bottom and thus stirring
the substrate and uncovering hidden preys. Another tactic was to charge upon prey concentrated in the shallows. The least
common tactic was to pick out prey adhered to the substrate. The first tactic is widespread in several species of marine rays in the
Dasyatidae, whereas the remainder (especially picking up prey on substrata above water surface) may be restricted to the...

The more stirring the better: cichlid fishes associate with foraging potamotrygonid rays
Provedor de dados: 83
Autores: Garrone-Neto,Domingos; Sazima,Ivan.
One hunting tactic of freshwater rays (Potamotrygonidae), termed "undulate the disc and stir substrate", is here reported to attract
cichlids at two sites in the upper Paraná River. The ray species involved in such association are Potamotrygon falkneri and P.
motoro, whose activity attract four cichlid species, namely Crenicichla britskii, Satanoperca pappaterra, Cichla kelberi, and
Geophagus proximus, the two latter non-native species to the study area. The cichlids approach a ray when it begins to stir the
substrate and form sediment clouds, and remain close to the ray during this activity only. The association is here regarded as
following behavior even if very transient.

Trichomycterus maracaya, a new catfish from the upper rio Paraná, southeastern Brazil
(Siluriformes: Trichomycteridae), with notes on the T. brasiliensis species-complex
Provedor de dados: 83
Autores: Bockmann,Flávio A.; Sazima,Ivan.
Trichomycterus maracaya, a new species of Trichomycteridae, is described from a streamlet in the upper rio Paraná, Poços de
Caldas, State of Minas Gerais, southeastern Brazil. The following putative autapomorphies distinguishes T. maracaya from
congeneric species: 1) row of lateral blotches not forming a stripe at any phase during ontogeny; 2) superficial layer of
pigmentation of juveniles and large (presumably adults) specimens consisting solely of scattered chromatophores. Furthermore,
the new species is characterized by a combination of yellow ground color in life and mottled pattern formed by small to
medium-sized, brown, irregularly-coalescent, well-defined deeper-lying blotches, and more superficial dots on the body.
Trichomycterus maracaya is...

Does the association of young fishes with jellyfishes protect from predation?A report on a failure case
due to damage to the jellyfish
Provedor de dados: 83
Autores: Bonaldo,Roberta Martini; Krajewski,João Paulo; Sazima,Ivan.
The fish-jellyfish association is regarded as a temporary symbiosis believed to protect the fishes from predators. Here we report on
juvenile scads (Trachurus lathami) associated with the jellyfish Chrysaora lactea, opportunistically preyed on by the grouper
Mycteroperca acutirostris while the medusa was being damaged. The predation instances occurred when a couple of the filefish
Stephanolepis hispidus approached the jellyfish to nibble on its umbrella. The feeding of the filefish caused a momentary
disturbance of the defensive association, perceived and capitalised on by the watchful grouper, an opportunistic and versatile
hunter. Before and after the disturbance, the protection offered to the young fish by the jellyfish showed to be effective, which...

The almost invisible league: crypsis and association between minute fishes and shrimps as a possible
defence against visually hunting predators
Provedor de dados: 83
Autores: Carvalho,Lucélia Nobre; Zuanon,Jansen; Sazima,Ivan.
Camouflage is one of the most widespread defence modes used by substrate-dwelling animals, whereas transparency is generally
found in open-water organisms. Both these defence types are regarded as effective against visually guided predators. We present
here three assemblages of similarly-sized freshwater fish and shrimp species which apparently rely on camouflage and
transparency to evade some of their potential predators. In one of the associations, there is a transition from cryptic colours and
translucency to transparency of the component species according to the position each of them occupies in the habitat. The likeness
between the fishes and the shrimps is here regarded as a type of protective association similar to numerical or social mimicry....
