Psammoactinia antarctica was an encrusting,
gastropod shells inhabited by hermit crabs of the genus
Paguristes.
The Psammoactinia colony began with a
gastropod shell. The colony then grew past the aperture of the shell and formed a tube that conformed to the hermit crab
’s shape and growing pattern.
