Large Nudibranch of at least 30 cm in size. Mostly grey brown in colour with appendages all over and large cerata. They have a strange 'mouth', I think called oral-hood, which they can stretch on the sandy bottom to filter feed. Check-out the video of them feeding here : https://www.facebook.com/askkang/videos/...
Sandy bottom and rubble bottom where they are very well camouflaged when not moving.
