Diet: Carnivorous. Often found in association with the bryozoan
Orthoscuticella ventricosa. Eat by inserting their proboscis
into their prey (also anemones and hydroids).
- Comments:
- Pycnogonids look like spiders and have four, five or six pairs of
legs, generally ending in claws. The body is very small, with long,
slender legs. This class contains more than 1000 species, however most
are less than 10 mm and therefore are rarely seen.
