What is Sessility (zoology)?
'''Sessility''' comes from the word '''sessile'''. In [[biology]], it means to stay in one place on the ground. It is the opposite of [[motile]]. It is mostly used for [[ocean|marine]] and [[freshwater]] [[species]]. They often have [[larva]]e which are motile, float or swim, and adult forms which are stationary. Many sessile forms can move from place if they need to. These life forms choose a suitable place, and stay fixed as long as they can. They usually secrete some substance which holds them on.
