•The larvae can smell the mucous in a predatory fish’s mouth and will tear themselves in half to increase the chance that one of them will survive.
•The larvae will also select heavy sand grains and store them in their stomach so they act like a weight belt, in some areas they eat heavy magnetite grains and so are magnetic.
•They are covered in spines on their underside that propel them through the sand
•On the spines they have cilia (little tentacles) that gather food.
•Bonnet shells and starfish are their enemies
•They are social animals
•They have an extra long tube foot which comes out of the sand and releases sperm and eggs into the current.
