This document summarizes different types of shellfish and fish. It divides shellfish into molluscs like mussels and oysters, and crustaceans like shrimp and crab. It then describes different types of fish, including round and flat whitefish like cod and sole, cartilaginous fish like sharks, and oil-rich fish like salmon and mackerel. It also distinguishes between demersal fish that live near the seabed, and pelagic fish that swim in mid-waters.

Frogs are an amphibious group that lives near ponds and lays eggs in water, with the greatest diversity found in tropical rainforests. However, frog populations have declined significantly since the 1950s, with some species now endangered or threatened due to threats like habitat loss from logging and fires as well as other issues, putting the approximately 4,800 known species at risk.
