Larva: Actinotrocha pallida Schneider, 1862
Last update: February 9, 2003
Extended specimens up to about 140 mm, diameter 0.3 to 1 mm.
Sexual reproduction: hermaphroditic, ova freely discharged in the sea-water; males with large, glandular lophophoral organs.
Phoronis pallida is embedded vertically in soft sediments, generally sand to muddy sand. Santagata (2002) cites a commensalim within the burrow of the thalassinid shrimp Upogebia pugettensis in False Bay (Washington, USA).
