fish diversity and speciation
Description : I am studying the basics of Marine biology and have to ;

1) explain why there are so many species of fish

2) outline the potential explanations as to why fish show such high levels of diversification

3 ) evaluate the supporting evidence

Can anyone help me with this or send mea link to a site where I can find this kind of information.? So far I have evolution and environmental reasons but nothing in enough detail to really expalin!!
Thanks in anticipation
