Cnidarians and Mollusks: August 3rd-6th


Our first week of phyla-based animal studies will start with an overview on how scientists classify different creatures, and what characteristics help them deal organize the chaos!

Shrimp, kelp crabs, lamp shells, oh my! We kicked off our new theme by looking at why and how life is organized in groups, and what a phylum really is. Then we looked into cnidarians and mollusks, the things that make them what they are, and then got to know both some classic and more exceptional species in these phyla who inhabit the Centre and the Sidney Marina.

To review:

CNIDARIANS include jellies, anemones, corals and hydroids. They have radial symmetry (like a circle), stinging tentacles arranged around the entrance and exit to the digestive system, and exist mostly as a polyp or a medusa.

MOLLUSKS are a strange assortment of animals that typically have a muscular foot, a mantle (body wall containing internal organs and often a cavity), a shell excreted by the mantle and a radula (cheese grater tongue).
