Marine Big 5 Daily Blog 15 May

Whale Watching near Cape Town, South Africa Welcome to Gansbaai, home of the Marine Big 5.
Trip Summary 15 May 2026:
Another busy day here at Marine Dynamics has come to an end. Throughout the day we had the chance to encounter some Bronze whaler sharks around the local Shark cage diving vessels, including our own, Slashfin, anchored within the Shallows. The critically endangered African Penguins were seen by some out at sea, and the playful Cape fur seals of Geyser Rock were cooling themselves down in the chilly waters of Shark Alley. Roaming the deeper waters, unfortunately is has been rather quite apart from some sunfish sightings as well as sightings of Shy Albatross. Today two of the endangered Indian Ocean humpback dolphins have also made an appearance in coastal waters!

What species did we see today?
African Penguin African Penguin
As one of only 17 penguin species left in the world (and the only one on the african continent), the african penguin often breed in offshore colonies, such as Dyer Island.
Cape fur seal Cape fur seal
With a local population of 60,000, it's no wonder our guests capture so many photographs of these wonderfully playful marine mammals.
Bronze Whaler Shark Bronze Whaler Shark
The Bronze whaler (also known as Copper sharks) here in Kleinbaai are very curious and interactive. These sharks eat mostly fish, with sardines being one of their favourites.
Indian Ocean Humpback Dolphin Indian Ocean Humpback Dolphin
Humpback dolphins are an endangered species, with small populations living very close to shore, typically in water less than 25m deep and an average home range of 120km. Their proximity to land makes these animals particularly vulnerable to human influence.
