Ecology
Reef-associated. Tropical

Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Variable number and placement of tubular and pointed spines on the chelifores and legs. No lateral process tubercles or spines; anterolateral corners of the cephalic segment lack any form of small tubercles.
Most pycnogonids are carnivores feeding on soft-bodied organisms such as hydroids, soft corals, anemones, bryozoans, small polychaetes and sponges. Some consume algae, microorganisms or detritus (Ref. 833).
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.
