Field Notes

Description:

Formerly referred to as Chromodoris coi. Found singly or in pairs, they feed on hydroids, coral, sponges and sea anemones.

Habitat:

Coral and rocky reefs among sand and rubble areas, throughout the Pacific seas.

Notes:

I've seen this nudibranch at various depths, from as shallow as 15 meters to as deep as 30 meters. It's delightful to watch them when they're flaring their mantles.

[Update] Added a video of this nudibranch, which I took on 1 April 2012.

In keeping with new scientific data, this nudibranch has been reclassified from Chromodoris coi to Goniobranchus coi.

Thanks, Emma! I was able to make use of a video lamp...but I still think I have a ways to go towards creating professional-level videos. :)

I just use a Canon S95 without strobe as well. Wishing I can upgrade soon hehe. Will definitely let you know if a Davao trip will be in the works. Going to Apo Reef this January though and want to explore other areas outside of Batangas. Oh yeah the habagat can be a drag. Went to Bohol last July and the seas were quite rough. :-)

Thanks, Eric. As you might have noticed, I'm a big nudi lover, so I'm trying to gather as many photographs of them as I can. I use a Nikon P7000 with a Fantasea housing -- just your basic setup as these things tend to be quite expensive (I don't even have a strobe yet). Best time to dive Davao would be in the summer, but since the weather here's pretty much the same year-round, even December is a good time for diving. I guess I should say that July-August, however, is the least favorable season for diving. This is due to the habagat monsoon. Do let me know if you decide to come over!

Love your Nudi collection. What camera do you use? Also when is the best time to dive in Davao? :-)
