Hydrostatic Skeleton of an Anemone One requirement of a hydrostatic skeleton is a fluid-filled compartment that can be closed to the outside. What part of an anemone fulfills the requirement for this compartment?[1] What characteristic does the fluid within the compartment need to possess so that its volume doesn’t change when pressure is applied?[2] A hydrostatic skeleton is very useful for an anemone. They live in crevices of rocks and can become long and skinny to extend out of the crevice to feed, but if danger approaches, they can shorten and shrink down into the crevice. When danger passes, they return to long and skinny. The contraction of what set of muscles allows them to change from short and fat to long and skinny (as shown in the diagram below)? Circular or Longitudinal [3] If unable to see the image, use this link.
