This week’s jellyfish photo comes from the National Geographic 2012 Photo Contest. The photo was taken by Geo Cloete in Cape Town, South Africa. This is a great photo from a region where not much is known of the local jellyfish populations. The caption misidentifies the jellyfish in the middle supposedly being eaten by the sea nettles (The two sea nettles are a very cool species, Chrysaora fulgida). The jellyfish in the middle is not a crystal jellyfish, a hydrozoan, but in fact a specimen of Drymonema sp., a scyphozoan. It is difficult to tell but it appears the Drymonema or ‘pink meanie’ has actually grabbed the two sea nettles and has begun digesting their oral arms. In other parts of the world Drymonema is a voracious moon jelly predator and appears to have similar feeding habits as another jelly, Phacellophora, which is capable of taking down sea nettles as well. This is a great example of predation that goes on between jellies in pelagic waters but illustrates why we need to study this region more. Many of the jellies off the South African coast are poorly understood and need to be reviewed, for more information on jellyfish from South Africa check out the SA Jellywatch page.
