Photographer records remarkable nudibranch behavior

Brad Pryde captured an image of mating nudibranchs whilst diving in Tulamben, Bali in November 2010. He entered the image into the Ocean Art Photo competition 2010 in the compact camera behavior category where it received third prize and as a result of which it was viewed by Dr. Richard Willan, Curator of Molluscs at the Museum and Art Gallery of the Northern Territory, Australia. He determined that the image shows reciprocal mating between two different species, the first time that this has been recorded. For the record, the two molluscs are a Risbecia tryoni (above) and a Risbecia pulchella(below.) He concluded that:

“So certainly, these species have never heard of sex as a species-isolating mechanism!”

Daily Mail reports on manta and mobula fishing. Photo

Daily Mail reports on manta and mobula fishing.

The UK Daily Mail has published an article about the fishing of manta and mobula rays. The paper states that Chinese practitioners believe the consumption of the ray’s gills helps reduce toxins in the blood by purifying and cooling it, reducing body temperature and aiding blood circulation, and that they boost the body’s immune system. One kilogram of gill rakers from a mature Indonesian manta sells for up to $200 in the dried seafood markets of China.

The rays are pulled from the ocean, either with fine gill nets or spears, and slaughtered to meet this growing demand and it is reported that in some fishing villages in Indonesia alone, fishermen are catching more than 2,000 mantas each year. Due to slow maturation and reproductive cycles, this level of harvesting is likely to be unsustainable, the paper reports.

New MPA announced for Cocos Islands Photo

New MPA announced for Cocos Islands

National Geographic is reporting that Costa Rica has just announced the creation of a large new marine protected area (MPA) around Cocos Island National Park. This new 9,640-square-kilometer MPA, called the Seamounts Marine Management Area, encompasses a group of deep seamounts located 35 miles south of Cocos, plus other important waters for shark and tuna nearby.

Purse seining for tuna is now outlawed in this area, but long-lining for tuna in some of its waters will still be allowed, which may still have a significant impact on the shark population. (Image © Conservation International/ photo by Sterling Zumbrunn.)
