Here are some more of Jan Kocian's photos to accompany his message [#14867] about Melibe leonina being washed into the 'jaws' of two sea anemones.

Locality: Whidbey Island, Puget Sound, Washington, USA. Pacific Ocean.
Depth: 15 feet. Length: 2 inches. 24 September 2005. old wharf. Photographer: Jan Kocian

A. Ventral view up into oral hood, showing sensory papillae lining the inside edge of the opening and the whitish opening of the true mouth.

B. Side view showing ramifying network of digestive gland ducts in both both wall and cerata.

C. Dorsal view of head. The orange mass in the 'neck' region is the ring of nerve ganglia which can be called the slugs' brain. The two thin white threads running forward from the brain are large nerves connecting to the rhinophores.
