Question

how hydrostatic skeleton facilitates locomotion in soft bodied animalss ​

Answer 1

$\huge{\green{\bold{\underline{\underline{\overline{\overline{\pink{Answer}}}}}}}}$

• Most cnidarians, flatworms, nematodes and annelids have a hydrostatic skeleton that consists of fluid held under pressure in a closed body compartment. These animals can control their body form and movement by using muscles to change the shape of the fluid filled compartments.

A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called the coelom. The organs of the coelom are supported by the aqueous fluid, which also resists external compression. This compartment is under hydrostatic pressure because of the fluid and supports the other organs of the organism
