Dendronotus iris feeding behaviour

May 19, 2006
From: Phil Garner

Concerning message #16629:

Very few of the D.iris seem to attach their eggs in the sand. Most are atached to the tube anemones themselves. As far as stinging, the nudis climb up the stalk, arch their back and bite the tentacles of the anemone, which retracts into its home. The nudi then crawls out, usually with a tentacle or two in its mouth for a tasty meal. I have seen other nudibranchs, including Cuthona divae laying eggs next to their food source.

Locality: Rancho Palos Verdes, 45-70 feet, California, USA, Eastern Pacific, 02 April 2006, Edge of a rocky reef on or near Pachycerianthus fimbriatus. Length: 1 inch to 10 inches. Photographer: Phil Garner.
