Invertebrates • Invertebrates are animals; they do not have a backbone.
Mollusks • Some live on sandy sea floors in great depth. • Some live in freshwater • Snails and slugs live on land • Every mollusk has a shell. • All have one foot • Some move slow and some move fast.
cnidarians • There are almost 10,000 cnidarians. • They have radial symmetry it is when you can divided it into a mirror images. • Cnidarians sting/stun there pray. • They only have one opining in there entire body. • THEY HAVE NO BRAIN!
Sponges • Sponges are hallow . • They have no brains. • They filter food. • Only there offspring move. • They can grow in fresh water.
Sponges Continued • You can use them when they are dead. • They are only2 cells wide. • Sponges are cold blooded. • My animal is a invertebrate. • Another name for a sponge is Porifera.
Echinoderms • They all live in the ocean. • They have Radial Symmetry. • They have no head. • They have a Endoskeleton. • They eat Clams, mussels, Corals, and sometimes starfish. • They have tube feet to walk.
Echinoderms continued • They have mouths that can open get its pray bring it back digest it bring the mouth back out and put the waist in the ocean.

Round worms • They live in oceans. • They are round. • They attach to the bottom.
Arthropods • Include insects, spiders, crabs and lobsters. • If you were to fill a bag with leaves in it, it will • Arthropods have segmented bodies. • They have bilateral symmetry. • Their bodies are encased in an exoskeleton. • Arthropods life cycle – they go through metamorphosis.
Arthropods continued… • Arthropods have egg, larva, pupa and adult. • Arthropods are cold blooded. • They are invertebrates too. • Some example of arthropods are – insects, spiders, crustaceans and scorpions.
Question Slide • Where do flat worms , segmented worms., round worms live ? • Where do cnidarians live? • What do sponges stick to? • What is the life cycle of a arthropods life cycle? • What are some exaples of echinoderms?
