What is Body cavity in animals:

• Many living creatures have a coelom, which is a hollow, fluid-filled cavity that serves as a protective cushion for their internal organs.
• The coelom serves as a skeleton in some creatures, such as worms.
• Internal organs can also move and grow independently of the outside layer of the body wall thanks to the coelom.

Acoelomates:

• An acoelomate is a creature without a cavity in its body.
• Acoelomates lack a fluid-filled cavity between the body wall and the digestive tract, unlike coelomates (eucoelomates), which have a real body cavity.
