Morah Katie: What do oceanographers study?
Augie: The Ocean.
Morah Katie: Scientists who study and learn about the life living in the ocean are called
Judah: Marine biologists.
Vertebrate vs. Invertebrate
We put our hands on our backs to feel our backbones. Animals with backbones are called vertebrates.
Judah: I sorted them by ocean vertebrates or land vertebrates. The birds are ocean and land because some birds fish in the ocean. The fish are ocean animals of course.
We played a sorting game to help us distinguish between marine vertebrates from marine invertebrates.
Ari: My crab does not have a backbone.
Matan: Does my polar bear have a backbone?
Kids: Yes, It's a vertebrate!
Sadie's sea star is an invertebrate.
Judah: My seahorse is a fish, so it is a vertebrate.
Evelyn: Well my penguin is a bird but it swims to catch fish.
Morah Katie: Would you like to look at our vertebrate chart?
Morah Katie: What do you see?
Evelyn: Birds DO have backbones! It is a vertebrate.
Matan: I have a tiger shark, it has a backbone.
My octopus doesn't have a backbone.
Nora: The whale has a backbone. I do too, only it's hiding behind my belly.
Angler fish are particularly exciting fish. They live in the abyss.
Augie: The angler fish has a backbone.
Nora: It has sharp teeth.
Ari: The bulb lights up.
Evan: It is hard to see in the dark so it makes light to catch food.
Morah Katie: Can you tell me about an invertebrate?
Judah: Mollusks are invertebrates.
Morah Katie: Can you name a mollusk for me?
Judah: A squid.
Ari: Octopuses don't have backbones, neither do jellyfish.
Judah: A mollusk is an animal. A squid is a mollusk.
Ari: A jellyfish is an invertebrate. It does not have a backbone.
We rearranged our ocean mural to better depict our understanding of squid and octopuses.
Morah Katie: Why did we have to move our ocean around?
Judah: Because octopus hide because they are soft and don't want to get eaten by tigers, tiger sharks I mean.
Evan: They live in dens.
Morah Katie: Octopus and Squid are similar. Can you tell me how?
Augie: They both have tentacles.
Evan: They are both invertebrates.
Abe: They squirt ink.
Morah Katie: How are squid different from octopuses?
Abe: They swim out in the open ocean.
Augie: They have 10 tentacles. Two of the tentacles they use to catch food.
Morah Katie: Can you tell me about other marine invertebrates?
Judah: Sea stars are invertebrates. Their mouth is underneath them and they spit their stomachs out on their food and then pull the whole thing inside again.
Olivia S.:They move really really slowly.
Matan: (with a slight cry) My star fish lost it's leg!
Ari: That's ok Matan because it can just grow it back.
Augie: Sea anemones are invertebrates.
Abe: They are like jellyfish because their tentacles zap their food.
Augie: But not the nemo fish
Morah Katie: Clown fish.
Morah Katie: Clown fish and sea anemones work together, the clown fish brings back food and the anemones keeps it safe from bigger fish.
Judah: I know that there are thousands of animals in the ocean.
Olivia S.: I know that dolphins have backbones.
Evelyn: I know that whales spout water out.
Abe: I know that squid live in the deep dark water and squirt ink and are similar to octopuses.
Maya: I know that sea turtles have backbones.
Asher knows that jellyfish don't have backbones.
Evan: I know that squid don't have a backbone, they are invertebrates. Their heads look oval.
