Chapter 32, Problem 15TYK

Summary Introduction

To review:

The making of a hypothesis to explain the observation related to the shark and rays feeding behaviour, as despite of their predatory feeding habit, largest species feed on plankton.

Introduction:

The largest fishes present in the ocean depends on sea’s smallest organisms for their food. It includes a number of massive plankton-feeding elasmobranchs. Elasmobranchs is a group of fishes that includes rays and sharks. These fish species are evolved the adaptations to gulp a huge amount of water followed by filtering of plankton, shrimp and small fishes. These filter- feeding species evolved their particular diet and feeding morphology independent to each other.
