Question

body fluids of sharks and colenterates can be termed as

Answer 1

The body fluids of sharks and colenterates are termed as Hypertonic.

• Sharks are marine mammals and are cartilaginous. They have adaptations that are osmoregulatory, allowing them to to withstand their environment's salt concentrations.
• They can build up and withstand high urea concentrations. Urea is poisonous to most species, however their tissues are modified to function at urea concentrations.
• The high concentration of urea makes the body fluids highly hypertonic to the water at sea resulting in a net water inflow. They have kidneys which are well developed and are capable of excreting huge quantities of urine.
