Pycnogonids in their natural environment, near possible food sources. a Callipallene margarita and its surroundings mainly built-up by red algae, Clavularia octocorals, and organic debris; Southern Chilean fjords, photo: Kaitlin McConnell. Pycnogonid indicated by arrow. b Female (right) and male (left) Achelia langi under a stone in wave dominated upper infralitoral near a Polycirrus polychaete; note male carrying fertilized eggs; Northern Adriatic, photo: Roland Melzer. c and d Pallenopsis yepayekae; C on a plumulariid hydrozoan. The pycnogonid may be feeding on the polyps, but this cannot be certainly determined. Southern Chilean fjords, photo: Roland Meyer. D On red algae, well camouflaged by a “roof-garden”.
