Invertebrates
Invertebrate Classification
What is an Invertebrate?
Invertebrates are animals that do not have _________________________.
97 % of the animal kingdom is made up of invertebrates.
Insects and some other invertebrates have ____________________________.
An Exoskeleton is a hard outer covering that protects an animal’s body and gives
it support.
There are six groups of invertebrates. They are:
1. __________________________-Sponges
Sponges Characteristics
They look like plants but they are animals.
Sponges stay fixed in one place-_________________________________.
Their bodies are full of holes and their skeleton is made of spiky fibers.
Water flows through the holes of their body which enables them to catch food-filter
feeders.
2. _________________________________: Corals, Hydras, and Jellyfish
Characteristics
Corals look like plants but they belong to the animal kingdom.
They have soft tubelike bodies with a single opening surrounded by armlike parts called
tentacles.
They feed by catching tiny animals in their tentacles.
Hydras have tentacles that catch their food.
They move from place to place-_____________________________________.
3. Worms: Flatworms, Roundworms, and Segmented worms
Worm Characteristics
Worms are tube-shaped invertebrates which allows them to be put into groups.
They can be found in both land and water environments.
a. ____________________________________________-Flatworms
They have a head and a tail, and flattened bodies.
A tapeworm is a flatworm that can live inside the body of animals and
humans.
__________________________________
b. ___________________________-Roundworm
They have rounded bodies.
Includes Ascaris, hookworms, Trichinella, & pinworms
c. __________________________-Segmented worms
The _________________________________ belongs to this group of
worms.
Body divided by grooves into ______________________________
Evolved from roundworms.
Have a real circulatory system.
Rudimentary nervous system.
___________________________________________________________
4. _______________________________________-Characteristics Starfish and Sea Urchins
Have tiny tube feet and body parts arranged around a central area.
No ________________________
Rudimentary nervous and circulatory system
The hard, spiny covering of the starfish gives the animal protection.
Can ____________________________________ lost or injured parts.
5. __________________________________
Mollusk Characteristics
A ______________________ body
Most have internal or external _____________________
Muscular foot and/or tentacles
Distinguishable head and foot region
Have a heart, blood vessels, digestive system and nervous system
________________________: a series of teeth on cartilage base for feeding
include snails, sea slugs, octopuses, squid, and bivalves such as clams, mussels and oysters.
6. Arthropods
Arthropod Characteristics
Arthropods are a group of invertebrates with _____________________ legs and hard
exoskeleton that protect the arthropod.
As it grows, it _______________________, or sheds its old exoskeleton.
Then it grows a new exoskeleton that allows its body to continue to grow.
The largest group of arthropods are insects.
Arthropods: Insects, Spiders, and Centipedes/Millipedes
__________________________________ exoskeleton-must be shed during growth
Paired appendages are jointed
