Photos of the South African fur seal (Arctocephalus pusillus) on Geyser rock/South Africa and of playing seals in the surf and under water
On the rocky island called Geyser Rock, in the immediate vicinity of Dyer Island, lives a seal colony of approximately 60,000 animals. As long as the South African Fur Seals (Arctocephalus pusillus) stay ashore and in the
shallow water in the immediate vicinity of the island there is no danger
for them. But if they start for their fishing hauls on the open sea – they dive 40 to 50 metres deep and are able to stay under water for up to five minutes – while swimming out and at their return, they have to cross a dangerous area which is tough for them. White Sharks lurk here. Seals are especially valuable for them. The danger is not over until the seals are back ashore. The high concentration of Great White Sharks is due to the seal colony.
Approximately 60 Hawaiian Monk Seals (Monachus schauinslandi) live on the Midway Atoll. These animals – they live in the north-west of the atoll on remote and uninhabitated islands – are only found here, and in no other place in the world. The seals reach a length of two metres and a weight of between 200 and 300 kilograms. They feed on
reef fish,octopusses and lobsters,which they find in the shallow water. But they are also able to hunt for their food in the open sea.
The Monk Seals are extremely sensible against human influence of any kind and are
threatened by extinction. There are three species of Monk Seals:
- Hawaiian Monk Seal (Monachus schauinslandi, estimated population approx. 1,000 animals)
- Caribbean Monk Seal (Monachus tropicalis, presumably extinct)
- Mediterranean Monk Seal (Monachus monachus, estimated population approx. 300 to 400 animals).
