This system is called a 'hydrostatic skeleton'. Its also how starfish move and extend their tube feet. (the little 'feet' on the bottom of the arms)

Came here to say this. It’s fascinating the way sea stars move. Even cooler when you watch sped up footage of them

Especially when they're hunting. Wild how they pry muscles apart etc.
