Creatures need a water skeleton, or hydrostatic skeleton, as it provides structural support and maintains shape without the rigidity of a hard skeleton. This type of skeleton relies on fluid pressure within a body cavity, allowing for flexibility and movement, particularly in soft-bodied organisms like jellyfish and worms. It also plays a crucial role in locomotion and helps protect internal organs. Overall, a water skeleton is essential for survival in various aquatic environments.
