Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Chelifiore: well developed, gathers food and use mouth to carry (Ref. 12). Tiny species with neck only half length of cephalic segment. Chelifore fingers equal to or slightly longer than palm, with teeth. Oviger fifth segment long in male, with laterodistal apophysis or knob bearing setae; strigilis with row of tiny fan-shaped denticulate spines, without terminal claw. Legs very slender, with few setae; cement gland openings not evident; propodus with 4 or 5 heel spines; main claw short, well curved; auxiliaries 0.6 length of main claw (Ref. 2115, p. 61).
It is an epibenthic species found on reefs (Ref. 95730), from coastal to upper slope (Ref. 19). Found to exclusively feed on hydroids, starves if no hydroids are present (Ref. 121217).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Pycnogonida are gonochoric and sexually dimorphic. During copulation, male usually suspends itself beneath the female. Fertilization occurs as the eggs leave the female's ovigers. Males brood the egg masses until they hatch. Life cycle: Eggs hatch into protonymphon larva then to adults.
