More on flourescence

Dear Bill,

Continuing with the flourescence [message #20387 ], here is a link that some people might find interesting:
http://www.nightsea.com/history.htm

It is true that there is very little information on why some nudibranchs have it and some not, but I believe it to be a very useful complementary tool that helps finding species that are otherwise hard to find.

Here is a photo I thought you might enjoy of Glossodoris sedna. Note the flourescence of the Porites coral [upper left of top photo]. The red surrounding the animal is algae which in daylight is brown.

Locality: Socorro Island, Revillagigedo Archipielago, 65 feet, Colima, Mexico, Tropical eastern Pacific, 12 April 2007, Rocky subtidal. Length: 32 mm. Photographer: Ali Hermosillo.

Cheers!
Alicia
