Peering out into False Bay, you see a small island teeming with life. This is Seal Island, a place of wild beauty and dramatic encounters. Seal Island is named for its massive Cape fur seal population. Over 60,000 seals call this rocky outcrop home.
Seal Island is more than just a seal sanctuary. It’s a stage for nature’s most thrilling performances. The island is located 5.7 kilometers off the northern beaches of False Bay near Cape Town. This island is a prime location to observe the great white shark. They come here to hunt the Cape fur seals.
Imagine the scene. It’s winter. The waters are cold. Great white sharks patrol the waters around Seal Island. They search for a lone seal separated from the group. Suddenly a shark launches itself from the depths. It explodes out of the water. A seal is caught in its jaws. This is breaching. Seal Island is famous for this behavior. Tourists come from all over the world to witness it.
The island itself is not hospitable to humans. It’s a 5-acre land mass. Seal Island consists of Cape granite. It rises only 4 to 6 meters above the high tide mark. The island is long and narrow about 800 by 50 meters. There is no vegetation or soil.
Human presence has left its mark. During World War II, a radar mast was constructed on Seal Island. It was used by a crew living in prefabricated huts. The tower succumbed to corrosion. It was blown over in a winter storm in 1970. Rusty twisted metal is all that remains. Ruins of huts from the sealing and guano-collection era are still visible. Some rock inscriptions made by sealers in the 1930s can still be seen.
Seals weren’t always protected here. In the mid-1800s, Cape Fur Seals were almost extinct. They disappeared from most of the island colonies of southern Africa. Guano mining harmed the seal population. The Fernandez Guano Operation collected guano from Seal Island until WWII.
Fortunately, things changed. In 1893, the government gave seals their first legal protection. Commercial hunting continued until 1990. The seal population steadily increased after the war. Today, Seal Island supports the largest breeding colony of Cape Fur Seals in the Western Cape. Between 12,000 and 18,000 seal pups are born each year.
Seal Island is also home to various bird species. 24 bird species can be found here. The island provides shelter for 80 pairs of African penguins.
But there’s been a shift in the ocean’s balance. Orca predations have put pressure on the white shark and cow shark populations. It seems the white sharks are reluctant to return to Seal Island False Bay.
Despite these changes, Seal Island remains a place of wonder. It shows the constant struggle for survival. It highlights the delicate balance of nature. Seal Island continues to fascinate scientists, tourists, and nature enthusiasts alike.
