Summary Introduction

Introduction: The animals tend to get adaptation to their environment in order to survive themselves. Hypertonic environment of the ocean is the selective pressure that shaped the kidney of these animals most efficiently to remove the toxins with less water. Marine animals live in a hypertonic environment of the ocean. Ocean contains higher solute concentration. Freshwater fish take in water by osmosis, so they produce a large volume of urine. By contrast, marine fish lose water by osmosis and produce little urine.
