Melibe australis - another colour variant

March 2, 2003
From: Bill Rudman

Here is another colour variant of Melibe australis.

Photo: Arrawarra, northern New South Wales, Australia under rocks at extreme low tide, 3 November 1982. 23mm long alive. AM C136167. Photos: Bill Rudman.

This is a translucent brown specimen with opaque white spots. The ramifications of the digestive gland are visible in the bottom half of cerata. The stalked cerata have theh chracteristic 'top'-like shape, with papillae restricted to the dorsal side. The cerata are easily autotomised. A large dorsal blood vessel can be seen in living animals running down the dorsal midline with branches to all the dorsal gills.
Best wishes,
