Chromodoris fidelis from Sri Lanka

From: Anouk Houben


Hi Bill,

These are two pictures of Chromodoris fidelis found in Sri Lanka. They differ a bit in colour and the second one seems to have a lot more ruffled edge. They are not commonly sighted here.

Locality: Second reef, Negombo, 15 m, Western Province, Sri Lanka, Indian ocean, 22 April 2007 and 05 December 2007, Silty reef. Length: 2.5 cm. Photographer: Anouk Houben.

Cheers,
Anouk

Dear Anouk,

It's interesting you should mention that C. fidelis is not so common in Sri Lanka as that is where the species was first found. It was named by Kelaart (1858) from specimens he collected at Trincomalee while stationed there as military surgeon to the British colonial troops.

AS you say, the animal in your lower photo looks to have a more ruffled mantle edge than usual. Overall it seems to be a bit bloated - as though the salinity was very low and it has taken in excess water - but that is just a guess.

Best wishes,
Bill Rudman
