|Description||Amphipholis squamata is a small inconspicuous brittle star, with a circular disc and spindly arms. It is grey/bluish-white in colour. The disc has a diameter ranging between 3-5 mm, with its dorsal surface covered in small scales. The arms are up to 20 mm in length (approximately 4 x the length of the disc) and consist of numerous marginal plates each with 3 or 4 conical arm spines. The mouth shields are small rhomboids, with very broad mouth papillae.|
|Additional information||This species is a deposit feeder collecting particles within its tube feet, and a suspension feeder via trapping detritus in mucus. It is hermaphroditic and the eggs are brooded and hatched as juveniles.|
