Short description Morphology

Length: Females, 0.4 cm; males smaller (Ref. 256); 3 mm body length; legs 15 mm long (Ref. 276). Body: Slender-cylindrical, with the lateral processes wide apart, each furnished with a dentiform projection at the tip. Cephalon: Frontal spines close together, the collar having sinus in the middle on the dorsal side. Chelifores and palps: absent. Abdomen: oblong-oval, truncate at the posterior end; armed with a short spine. Ocular tubercle: exactly in the middle of the cephalon, prominent, acuminate, the four eyes comparatively small, closer to the base of the tubercle. Proboscis: long and slender than the body, expanded in the middle. Ovigerous legs: male only, half the length of the body, with seven segments. Second segment: largest, the 5th segment larger than preceding or succeeding it, sharply curved; last segment triangular, with two short spines on the inner margin. Ambulatory legs: 3 times the length of the body, armed with scattered spines, unequal in length; 2nd coxal segment longer than taken together; femur twice as the coxal section and terminating outwards in a conical process, armed with two spines of different length. Tibia: 1 shorter. Tibia: as long as the femur. Tarsus: obliquely rounded. Propodus: four times longer than broad, terminating outwards in a sharp corner, inner margin furnished at the base with five spines, the two outmost placed side by side, terminal claw more than half the propodus. Auxiliary claws: less than half as the main claws. Body: translucent, with the intestine and its lateral expansions of a green color (Ref. 256). Proboscis: Detritus-gathering as a different source of food, lack chelifores, and capable of considerable movement at the region of the 'soft collar'; a number of bifid setae scattered on the surface and sometimes groups of tactile or chemosensory spines abundant around the mouths of this detritus-feeding forms. The mouth at the tip of the proboscis: triradiate structure; three lip-lobes and carry a number of setae (Ref. 12)

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Life cycle: release a number of eggs at each mating; represents the contents of a single femur (Ref. Ref. 12). Development site of larval associations: Obelia medusae and hydroids (Ref. 206).
