Sipunculidae
Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; depth range 1 - 370 m (Ref. 1840). Tropical
Pacific Ocean separates the two subspecies. Sipunculus phalloides phalloides: Caribbean from the West Indies, Barbados and Brazil; Eastern Pacific, from Costa Rica and Galapagos Islands; and, eastern Atlantic, off Ivory Coast. Sipunculus phalloides inclusus: Indonesia and southern Japan. Mostly tropical.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Sipunculus phalloides phalloides: large worm, has 35-41 longitudinal muscle bands (LMBs) and do not subdivide in glans region. Unattached nephridia. Nephridiopores are open between 4 and 8 LMBs. Spindle muscle, weakly developed. Ventral retractors originate from 1 or 2 LMBs and extend over 2-6 bands while dorsal start on 12-16 LMBs and spread over 2-6 bands. Sipunculus phalloides inclusus/i>: There is more fusion or splitting of LMBs from anterior to posterior (Ref. 1840).
Sipunculus phalloides phalloides: inhabits intertidal, shallow water species in the Caribbean, Eastern Pacific and Atlantic. Sipunculus phalloides inclusus/i>: Inhabits 1-370 m (Ref. 1840).
