There are three distinct groups of fish that ichthyologists study: bony fish, cartilaginous fish, and jawless fish. Ichthyology has a long history that began with simple observations and descriptions of fish over 200 years. The first known recorded observations of fish were documented by Pierre Belon in the 1500âs.
For fish as eaten by humans, see Fish as food. For other uses, see Fish (disambiguation). A fish is any member of a group of animals that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores.
