Hypselodoris apolegma - feeding record [2]

March 19, 2007
From: Richard Swann


Hi again Bill

These shots were taken around half a kilometer from the one's in the previous message [#19709 ] taken a couple of months later. I feel that the sponge has almost entirely been consumed however I really don't know very much about sponges so I may be way off here. As you can see the slugs seem to be the same colour form as my previous message, again i look forward to hearing your thoughts.

Locality: Mabul island, , 24 meters. eggs at 19 meters, Sabah, Borneo, Celebes Sea, December 2006, Fringing reef slope. Photographer: Richard Swann.

I have also attached another shot of egg laying in this form but if it is of no interest please just disregard it.

Best regards
Richard

Dear Richard,

Thanks for some more valuable information. The sponge is a species of the dysideid, Euryspongia, probably the same species as in your previous message. Many sponges have different growth forms. This looks very like a spnge being eaten by H. bullocki in an earlier message of Gary Cobb's [11160]. The egg ribbon looks very like others reported for this species.

Best wishes,
Bill Rudman
