Dolabella auricularia from Sth Korea

July 18, 2005
From: Dong Bum Koh

Dear Bill,
Here are some photos of Dolabella auricularia (Lightfoot, 1786) for the Forum.

Locality: Hwa Soon, Jeju Island, Sth Korea Depth: 4 m. Length: 50 mm. 12 Dec. 2004. Sandy bottom with Rock Wall. Photographer: Youn Byung Ro

The uppermost photo is a anterior view & the lowermost photo is a closeup of posterior view of the animal. We can see the central hole (= exhalent siphon) in center of the lower photo. Compare this animal with my prior message (#7352: size about270 mm), its size, color, shape... are different.

After take some live photos, I sampled it and dissected the animal and extracted the hidden shell as shown in the middle photos.

Best regards,
Dong Bum Koh

Dear Koh,
Thanks for these photos which show the shape and position of the shell very well. This species is quite varaible in colour and as your show, is very well camouflaged in its normal environment. I can't say I have seen one with yellow-tipped papillae before.
Best wishes,
Bill Rudman
