6. Remarkable Fishes Discuss: phylogeny, distribution, size, prey and predators, reproduction, growth, brain size, other traits. Myxine glutinosa Latimeria chalumnae Rhincodon typus Engraulis ringens Mola mola

7. Need To Know Based on common ancestry, the 33,000 known species of fishes are classified into 6 Classes, about 60 Orders and about 500 Families. All fishes and tetrapods had a common ancestor about 600 million years ago; tetrapods (about 27,000 species) split off from lobe-finned fishes about 400 million years ago. Know the Classes of fishes and their main characteristics
