Physalia belongs to the phylum Cnidaria. It is commonly known as Portuguese man- of-war as it has a gas-filled bladder which sits above the water and somewhat resembles an old warship.

Limulus belongs to the phylum Arthropoda, commonly called king crab. It is considered a living fossil. The survivors of previously more diverse lineages that originated millions of years ago and persisted with little change are known as living fossils.

Ancylostoma belongs to the phylum Aschelminthes. It is a parasitic nematode worm that lives in the intestine of human beings. It is commonly called hookworm.

Pinctada belongs to the phylum Mollusca. It is commonly called pearl oyster.
