Which of the two sea animals do not have streamlined and bilaterally symmetrical body?
Answers
Answer:
Star Fish
Octopus
Explanation:
Star Fish: Their official shape is just alike a star. This makes them unique from other sea animals. A Starfish has amazing powers of regeneration. One of its best defences against predators is his ability to drop off an arm that's grasped in a predator's mouth. Assuming the predator doesn't bite off the arm, the starfish can intentionally separate it from his body to aid his escape.
Octopus: This sea animal has eight(8) legs, which help it to protect from other animals. The Octopus swims head-first, and in times of danger can expel water through the end of its mantle, propelling it like a jet through the water. It can squeeze its body through tiny gaps to shake off predators.
