Question

few lines on crab according to class 3rd​

Answer 1

Answer:

(1) Crabs have ten legs and are referred to as decapods. Like spiders, crabs also have legs that can bend at the joints.

(2) The front two legs of the crab are usually called claws and are not used for locomotion. The claws are also called pincers, and can be big in some crabs. Swimming crabs use the hind legs as paddles to move when in water.

(3) Male crabs usually have blue colored claws, while female crabs have red colored. The distinct red color makes them look like they have applied red nail polish!
