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.
Fish are vertebrates which are animals with backbone and they survive in water with the help of gills that help them to breathe. Their body is streamlined to suit swimming in water. There are as many as 25000 different types of fish in the different water sources all around the world.
