3rd Grade Biology: Animal Kingdom
- 1. 3rd Grade Biology: Animal Kingdom by Ita Rodríguez
- 3. INVERTEBRATES Invertebrates •Do not have backbones •Are multicellular •Most have tissue
- 4. INVERTEBRATES Invertebrates •Most reproduce sexually •Most can move •Most are symmetrical
- 6. INVERTEBRATES: SPONGES Habitat •Most live in seawater although a few species live in fresh water •Polar region to tropics •Most live in clear water Sponges
- 7. INVERTEBRATES: SPONGES Characteristics •Sponges take in water from pores and release it at the top •The water holds the sponge up •They feed and "breathe" by filtering the water that flows through them •Phylum Porifera Sponges
- 8. INVERTEBRATES: SPONGES Life Cycle •Larvea: Move around freely •Adult: Anchor themselves in one place forever •Death Sponges
- 9. INVERTEBRATES: SPONGES Asexual •Fragmentation •Budding Sponges: Reproduction Sexual •Most sponges are hermaphrodites
- 10. INVERTEBRATES: SPONGES Special Adaptation •When they find that the water circulating through them has more silt and large particles that could block their canal system, they automatically close their pores and protect themselves! Sponges
- 13. INVERTEBRATES: SPONGES Sponges: Reproduction This is actually a coral, but they reproduce similarly

- 25. *Special note: Comb jellies are a side step away from jellyfish. They are in the phylum Ctenophora. They look similar, but are different in some important ways. - Comb jellies use cilia flapping on their sides to move. They do not contract a bell like jellyfish. - Comb jellies use cells called colloblasts to capture their prey. These cells stick to the prey, not harpoon them. - They have two (2) holes. While true jellies have a sealed bell with only one opening, comb jellies have a small opening at the top of their body and one at the bottom so that water can flow through them. - They often have plates for protection on the outside of their bodies.
