MANGROVE JELLYFISH: AN UPSIDE-DOWN UNDERWATER LIFE
The Mangrove Jellyfish Cassiopea, also called the ‘upside-down jellyfish’ for reasons I needn’t dwell on, is the only member of its particular jellyfish family. These creatures prefer warm waters, and typically live upside-down on the sea-bottom, which no doubt makes catching prey very simple. They can be found individually, though more likely in large groups, with individuals displaying different shades and colours.

The Mangrove Jellyfish has one of the milder stings of the numerous species, though human reactions to the sting will vary with the individual. A greater problem may come from swimming around or over a mass of these creatures. Their stinging cells are excreted in a transparent mucus which may invisibly cover the unwary swimmer. Apart from skin-irritation and a rash, the stings are apparently very itchy. My guess is that scratching can only make things worse (cf No-see-ums…). The first of the two videos below was taken recently by Sarah Bedard (to whom thanks) who “found a great tidal pool full of them at the end of Rock Point Road, Treasure Cay (Abaco)”. The second is short, but with some amazing footage of the Jellyfish in action.
