These animals live in marine environments, close to rocky shores.
Diet and foraging method
Social organisation and mating system
Sea spiders reproduce externally following a brief "courtship", the male then looks after the eggs. Not much is known about the development of the larvae.

Sea spiders have a tiny body and many of their organs are too large to be housed here, so are actually located within their long legs!
