There are a wide range of fish species along the coast outside Cape Town, as well as seaweed and invertebrates.
False Bay is occasionally host to visiting fish coming in from warmer regions. Even turtles have been spotted in the bay, brought in by the east coast current. You might be able to spot them when diving at East Shoal, or one of the other spots in the bay. This beautiful offshore rocky reef site in False Bay has a depth of about 25 meters, and is said to be made of Table Mountain sandstone. It is not the most frequently used diving spot, as it is a bit far from the nearest launch site. However, the marine life is amazing, with an astonishing density of echinoderms. Much of the reef is covered by a mat of brittle stars.
It is known that great white sharks feed at nearby
Seal Island. It is several kilometers away, and scuba divers have not reported sightings of these big fish at East Shoal. However, it could be wise not to hang around in mid water or on the surface for long. Decompression dives are not recommended here for this reason. If you do want to dive with sharks, there are many options for joining organized shark diving trips in South Africa.
