Crustaceans are a large group of arthropods that include crabs, barnacles, shrimp, and krill. They are distinguished by having two-parted limbs and a larval stage called a nauplius. Their fossil record shows they have remained largely unchanged since the Triassic period. Crustacean bodies are divided into three regions - head, thorax, abdomen - and covered by a hard exoskeleton. They typically have biramous appendages and an open circulatory system with a heart near the dorsal surface.
Mollusks are a large phylum of invertebrate animals that include classes such as bivalves, cephalopods, gastropods, and rostroconchia. They generally have bilateral symmetry, respiratory organs like gills or lungs, an open circulatory system, and a foot and radula. Key characteristics include a complex digestive system with two openings, the lack of a cell wall or chloroplasts, and multicellularity. Bivalves have two-part shells, cephalopods are marine with arms and tentacles, gastropods range in size and many are hermaphrodites, and rostroconchia have a single pseudo-bivalved shell
Insects are a class of arthropods that have three body segments, three pairs of legs, and two antennae. They display two types of metamorphosis - complete metamorphosis with four life stages (egg, larva, pupa, adult), or incomplete metamorphosis with gradual changes through molting. Insects are highly diverse and make up over half of all known living organisms, with over a million described species.
