FIGURE 1 in Sponges from Clipperton Island, East Pacific
FIGURE 1. Map of Clipperton Island (10°17–18'N 109°11–13'W), indicating approximate positions of diving stations where collections of sponges were made. Asterisks indicate positions of the Clipperton 1994 Expedition localities (material shared between CASIZ and ZMA), dots indicate positions of the Jean-Louis Etienne Clipperton Expédition 2004/5 (material kept in MNHN). For details of the collecting positions of individual samples of the various sponges cf. the descriptions under each species heading. Positions of the two samples obtained by the 1939 the motor cruiser Velero III visit to Clipperton are not indicated as they are unclear ('rocks to south of landing place'). Inset showing position (arrow) of Clipperton Island in the East Pacific.
