Pycnogonida from Costa Rica collected by Scuba Diving

Franz Krapp, Carlos Víquez


The knowledge of the pycnogonid fauna of Costa Rica is poor. This is the first report on Pycnogonida collected by scuba diving from both oceans of Costa Rica. Nine species from the Caribbean side and one from the Pacific coast are reported. We add eight species to the Caribbean fauna and one to the Pacific fauna of Costa Rica. No species new to science were encountered.
