What is the working definition of an animal? - Animals are multicellular eukaryotes that are heterotrophic and undergo a blastula stage Two problems associated with morphological classification? - 1. Convergent evolution 2. Minor mutations Why was the organism found in the 90s labelled as a bivalve mollusc? - Because it was consuming bivalve eggs and had traces of their DNA in its gut. What are some problems with molecular sequencing? - 1. Differences in mitochondrial and nuclear DNA ...

Phylum Porifera (sponges) multicellular organisms without tissues, organs, or body cavity Heterotroph organism that obtains energy from the foods it consumes; also called a consumer Spicules hard spear or star-shaped structures; made of CaCO3 (limestone) or silica (glass) Choanocyte line the gastrovascular cavity & capture food Amoebocyte digest & distribute food Osculum large opening at the top where excess water leaves Spongocoel large central cavity of the sponge

Grantia Characteristics - Eukaryotic Heterotrophic Multicellular Grantia Classification - Domain: Eukarya Kingdom: Animalia Subkingdom: Parazoa Phylum Porifera Common Name: Sponge Grantia Habitat - -Coastline of the North Atlantic -Intertidal regions Grantia Energy/Food Source - -Spongocoel - internal cavity lined with flagellated cells - beating of flagella draws water, fine organic particles & tiny organisms (bacteria) into the spongocoel through tiny pores of the body wall -Food ...
