Question

Do worms have a hydrostatic skeleton?

Answer 1

Hydrostatic skeleton:

1. The hydrostatic skeleton of earthworms is divided into segments.
2. In all soft-bodied animals, the hydrostatic skeleton is a sort of skeletal structure.
3. A fluid-supported skeleton is known as a hydrostatic skeleton.
4. The hydrostatic skeleton of earthworms is segmented.
5. The coelomic fluid in each segment is largely isolated from the fluid in neighbouring segments by muscle septae, allowing segments to function as independent hydraulic units.
6. The circular fibres act to elongate and thin the worm radially, whilst the longitudinal fibres shorten it and produce radial expansion.
