... The cuttlefish can change their
skin to be any color. They can
also change their body texture
to be any texture.
One important body part is the
cuttlebone because the
cuttlebone controls the
cuttlefish’s buoyancy.

... The weasel family belongs to the order
Carnivora. With the exception of the
river otter, all members of the weasel
family feed primarily on insects and
small rodents (Fig. 4). Their diet consists of whatever meat they can obtain
and may include birds and bird eggs.
As predators, they play an importa ...
... Although a rabbit is nearly twice the size of a weasel, this
little predator can still take one down. A rabbit provides a
lot of energy in exchange for the energy expended by the
weasel in catching it. A weasel will leap at the neck and
bite down, holding on tightly with all four paws to the
rabbit ...

Arachnidia: Spiders are the largest group of arachnids; Some spin a strong web of flexible protein called SILK; SPINNERETS are the
organs that produce silk. All spiders produce silk…but not all spiders spin webs. Web-spinning s ...

... larvae are leaf-shredders, which is a role often essential to the distribution of fine
particulate organic matter resources to filter-feeding invertebrates (Cummins et al. 1989,
Wallace and Webster 1996), which can control secondary production throughout the
stream community (Wallace et al. 1997). U ...
... prey items when they were captured and examined at the
end of this period (pers. obs.). Hence, it is clear that these
snakes rely upon ambush (‘sit-and-wait’) predation rather
than active foraging, at least during the times of year
when they remain on the rock outcrops. The snakes are
more difficult ...
... In the only marine study of this section, Robinson and Baum
(2016) present evidence for strong size structuring of trophic interactions in a minimally perturbed coral reef fish community:
trophic position scaled positively with size both within and across
species, and individual abundance declined co ...
... means “_stinging nettles_”. Cnidarians use _nematocysts__ to sting &
capture their prey then tentacles bring prey to their mouth.
Cnidarians have _radial___ symmetry, and use a gut for digestion.
Cnidarians come in 2 body forms; a polyp which is shaped like a __vase_,
or a medusa, which is shape ...
... Size: Although males reaching close to 3500 pounds have been documented, the
estimated average range is between 12-15 feet (3.7-4.6m) and 1600-2500 pounds in
weight. Females are slightly smaller than the males with an average length of 11-13 feet
and weight of 1100-2000 pounds. Calves at birth are a ...
... • Animals with radial symmetry look the
same from all sides and have no head,
front, or back.
• They do, however, have an oral surface,
where the mouth is, and an aboral
surface on the opposite side
• See figure 7.6 page 119

... devoid of prey. Following droughts, however, wetlands can be extremely productive,
rendering prey resources virtually unlimited for some species.
3. This study examines drought survival strategy and reproductive ecology of a small
aquatic snake Seminatrix pygaea (Cope) in an isolated wetland. Semina ...

habitat from activities such as logging and forest fires.
But experts are hoping to reverse the fortunes of the rarest big cat in the world with a

work against the fluid contained in the coelenteron, thus extending the polyps. Hydrostatic skeletons are also present in the
tentacles, allowing them to be extended to capture ...
... in order to confuse their attacker and allow the squid to escape. These fast-moving
carnivores catch prey with their two feeding tentacles, then hold the prey with the eight
arms and bite it into small pieces using a parrot-like beak. The esophagus runs through
the brain, so the food must be in smal ...

which types of prey are preferred. In one such study conducted by Missouri Cooperative
Fishery Unit researchers Wilbur Mauck and Dan Coble, pike were held in pools, ponds

... positive feeding responses. In natural situations Zoanthus has never been observed
to feed.
Palythoa polyps capture live prey with their tentacles and use these to hold the
prey against the peristome. Very few nematocysts are discharged and they do not
paralyze the prey. The behavioral response call ...
Ambush predators or sit-and-wait predators are carnivorous animals or other organisms, such as some nematophagous fungi and carnivorous plants, that capture or trap prey by stealth or by strategy (typically not conscious strategy), rather than by speed or by strength. In animals, ambush predation is characterized by an animal scanning the environment from a concealed position and then rapidly executing a surprise attack.
