Water covers 71% of the worlds surface, and 97% of that water is in the oceans. Oceans, while appearing infinitely large, are not an infinite resource. Oceans provide many important services and functions, most of which people may be unaware of, such as: nutrient recycling, primary production, provide shelter to many marine species, provide food […]

Anglers and visitors to the underwater world in our beautiful Plettenberg Bay may be familiar with a fish called blacktail Diplodus capensis, though perhaps the name dassie or Cape white seabream is more familiar. This is an oval-shaped fish which is primarily silver in colour with a black patch at the base of the tail. […]

Black Marlins are found in tropical and subtropical Indian and Pacific Ocean, preferring to stay […]
There are over 25,000 identified species of fish on the earth, but it is believed that there might still be over 15,000 fish species that have not yet been identified. There are more species of fish then all the species of amphibians (frogs), reptiles, birds and mammals combined.
“Picture of the day” We had a pod of ±2000 common dolphins in the bay this morning. We also had Brydes whales feeding in the bay. These dolphins are associated with diving seabirds (particularly Cape Gannets), Penguins and Brydes whales – all feeding on the same small pelagic fish (pilchard, herring, squid etc.)
“Picture of the day” On our 09h30 boat trip this morning we encountered 2 African Black Footed Penguins, previously known as the Jack Ass Penguins. They eat fish such as anchovies, pilchards, horse mackerel and round herrings, and to a lesser extent squid and crustacean such as krill.
“Picture of the day” Dolphins will work together as groups to contain fish in as tight a ball as possible. This cooperation ensures that every member gets their fair share. They have a built in radar that enables them to communicate, locate and stun fish.
