Diving with potato bass

Potato bass are probably the most curious fish of all. While scuba diving on reefs on the east coast of South Africa and Mozambique you are almost guaranteed a close encounter with this massive fish, which commonly grow up to 1.5m in length – making them one of the largest of all the coral reef predators in the region.

Also known as potato groupers, they are generally harmless and quite friendly towards scuba divers. Many times you will find yourself literally face to face with one of them. They tend to approach divers and hang around the group, enjoying all the attention. As an underwater photographer you cannot ask for a more amenable subject as they will provide you with all the angles and poses you need for a full shoot.

The situation may however get slightly nerve-wracking when you stop paying attention to them as potato bass can get jealous and start bothering you by trying to nibble on any loose pieces of equipment hanging from your dive gear! Groupers don’t have big sharp-edged teeth but do have rows of small needle-like teeth so anything that comes into their enormous mouth does not get out, so caution is advised. While this is an extreme situation in most cases you will find them amazing companions, that may stay with you during the whole dive, providing great photos and broad smiles all around after the dive.

I am an underwater videographer and wildlife media producer. I have spent the past 5 years on the east coast of South Africa and Mozambique staying at the most popular dive locations like Sodwana Bay, Aliwal Shoal, Tofo, Guinjata, Ponta d'Ouro. Aside from filming the underwater world I am a professional underwater guide and tour leader. Creatures of the Sea – Flashcards | Indian Ocean – is a concept project of mine to popularise knowledge about marine life species in a contemporary, fast-paced online media environment. Every episode is about a different specie of marine life and you will find everything from ferocious sharks, mellow turtles, friendly dolphins to colourful nudibranchs (sea slugs) and perfectly camouflaged fish and crabs. Watch all the episodes of Creatures of the Sea series on the Bart Videography Facebook page or can find all my video work on my website.
