Re: Feeding observations on Armina sp. 9

Dear Bill,

I don't know if you have looked at the description of Armina papillata Baba, 1933, but it seems to me that Armina sp. 9 is rather similar to that. I found specimens in Hong Kong that I identified with A. papillata though the colour of the dorsal surface was grey rather than black. However, the papillae on the head seem very similar. Other species with papillae are A. gracilis (Bergh, 1874), A. lugubris (Bergh, 1874), A. petersi (Bergh, 1866) and A. comta (Bergh, 1880). The number of papillae on the head differ in these species, and also the number of lateral lamellae (on the ventral surface of the mantle skirt).

I have discovered a very poor scan of the Armina papillata from Hong Kong. It was scanned from an old slide, so probably the poor quality is more the age of the slide than the scanner.

The specimen had been trawled during an international workshop.

Locality: Hong Kong. Depth: unknown. Hong Kong, South China Sea, Length: 60 mm. 17 April 1995. trawled. Photographer: Kathe Jensen
