Trapania reticulata from the Andaman Sea

November 23, 2009
From: Lawrence Neal


Concerning message #2396:

Dear Bill,

I think you may be interested to see these pictures of what I think is Trapania reticulata, from the Andaman Sea. This specimen was found crawling over algae- and sponge-covered rocks, just a few metres from the shore and in about 6 metres depth of water.

Locality: Tablamu, 6 metres, Phangnga, Thailand, Andaman Sea, east Indian Ocean, 14 November 2009, Rocky shoreline. Length: 23 mm. Photographer: Lawrence Neal.

It was crawling very quickly, similar to many types of Gymnodorid, and with its rather impressive sensory organs - large rhinophores and oral tentacles - I thought it might be a predator of sea slugs or other non-sessile organisms. I'm left wondering why this species needs to move so quickly and why so much sensory tackle?

This individual was also much bigger than any other specimen of Trapania I have ever seen (admittedly that's not many) at over 2 cm. It was actually fairly easy to see.

Thanks and all the best,

Lawrence

Dear Lawrence,

I am indeed interested in seeing another example of this rarely reported species. Your animal is remarkably big for a species of Trapania. Perhaps it's found something other than small kamptozoa to feed on?

Best wishes,
Bill Rudman

Trapania reticulata from Queensland

May 22, 2000
From: Stuart Hutchison

Dear Bill,
I can't find this one in any books either. I suspect it is a Notodoris of of some kind by the wings protecting the gills. This guy was about 8mm long in 30m next to the wreck of SS Yongala.

SS Yongala is about 40 nautical miles SE of Townsville, Queensland (on an open sandy bottom - inside the Great Barrier Reef).

Dear Stuart,
This is a very interesting find, as it is only the second record of this animal from anywhere. Your photo confirms the colour pattern of a brown reticulate pattern and yellow spots.

Have a look at some of the other species of Trapania (use the SEARCH button) to get an idea of their shape and variety.

Best wishes,
Bill Rudman.
