Following on from message 1 here are the photos of Doriopsilla miniata being eaten. In the Trio Island photos [upper and lower right] I saw the Gymnodoris attack the prey from the back. It extended something like a tube to suck the underneath of the prey. It seemed very powerful and even raised up the prey. But they struggled too long time I could not see the end. But in the Steep Island example [lower left] I discovered them just as the Gymnodoris attacked so I had enough time to witness that the victim was swallowed completely after 1.5 hrs
UPPER & LOWER RIGHT: Proboscis being inserted into body of the prey beneath the mantle near the gills. Trio Island, Hong Kong, April 2001. [Gymnodoris 4.5 cm long].
LOWER LEFT: Showing final stage of ingestion, body a wrinkled sac from which the viscera have been removed. Steep Island, Hong Kong. 8m depth. March, 2001 [Gymnodoris 5.5cm long].
