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.
Major groups of fish evolved during this period, often referred to as the age of fishes. See Category:Devonian fish. D e v o n i a n: Early Devonian: Early Devonian (419â393 Ma): Psarolepis: Psarolepis (speckled scale) is a genus of extinct lobe-finned fish that lived around 397 to 418 Ma.
