Recently, other groups such as mollusks, echinoderms, and annelids have been found in these systems (Solis-Marin & Laguarda-Figueras, 2010; Frontana-Uribe & SolisWeiss, 2011; Rubio et al., 2015); however, pycnogonids have never been found.
Most pycnogonids are small, with leg spans of less than one centimeter, in some species just a few millimeters, but some deep-sea species have leg spans of up to 60 cm (Arnaud & Bamber, 1987).
Reports of pycnogonids from Mexico have been sporadic.
Les Pycnogonides de la croisiere 1951 du President Theodore Tissier.
Pycnogonids associated with the giant lion's paw scallop Nodipecten subnodosus (Sowerby) in Ojo de Liebre Bay, Guerrero Negro, Baja California Sur, Mexico.
We chose to compare differences between the dark epibiont group, bulk water, and control group because there was no apparent photosynthesis on the pycnogonid cuticle in the control group.
Observations on the physiology and integumentary structure of the Antarctic pycnogonid Decolopoda australis.
Fine structure of the "slit organs" of the pycnogonid Anoplodactylus petiolatus (Anoplodactylidae).
Epizoites on marine invertebrates: with particular reference to those associated with the pycnogonid Phoxichilidium tubulariae Lebour, the amphipod Caprella linearis (L.) and the decapod Corystes cassivelaunus (Pennant).
In this study, we examined how epibionts affect local oxygen supply to temperate species of pycnogonids (sea spiders).
