Worm in a wedding dress

With the recent sighting of a whale shark, and turtles everywhere it’s easy to forget the little things that we see on our dive sites, and for some people the little things are the most exciting, because you have to work to find them! So today I would like to talk a little about Nudibranch, or often known as “Sea Slugs”. Nudibranchs can be seen all over the dive sites around Koh Tao due to the warm seas and the shallow depth of some of our dive sites, all you need to do is look a little harder to find them. They can vary in adult size from 20 to 600 millimetres, and are most often noted for their brilliant colours and striking forms. There are over 3000 known species of nudibranch worldwide but it is likely there are many more still yet to be discovered. All known species of nudibranch are carnivorous, feeding mainly on sponges however some species eat other species and their eggs, and some have been seen to eat their own species making them cannibals. So next time you go for a fun dive, look a little bit closer and you may end up seeing some of the most weird and colourful creatures that SCUBA diving has to offer.
