New to Nature No 23: Chromodoris socorroensis

Chromodoris socorroensis is a beautiful, translucent white to pinkish-coloured sea slug with large, salmon-red markings outlined by opaque white. Discovered under rocks in the Revillagigedo Islands off Mexico's Pacific coast, these molluscs are no longer than 10mm. Like the more than 3,000 known species of nudibranchs, this soft-bodied species sheds its shell after its larval stage and its delicate form belies its behaviour as a fierce predator of other marine invertebrates. Nudibranchs are noted for their amazing variety of often brilliant colours. International Institute for Species Exploration, Arizona State University
