South Carolina Bull Shark

Another shark video is making the viral rounds on the Internet. But rather than be one that invokes sadness or anger for depicting some poor trophy prize hung by its tail or a sea of shark fins drying in the sun, this short video from South Carolina illustrates a unique quality of what is considered to be one of the more aggressive sharks. Along South Carolina's North Myrtle Beach is House Creek which is fed by tens of smaller creeks and streams and ultimately spills out to the sea. This transition from fresh to saltwater makes for brackish water that some ocean fish are able to tolerate. One such animal is the bull shark. If you have not yet seen the video, a young woman, Sarah Brame, accompanied by her fiance and stepfather, was fishing off the dock at Cherry Grove Inlet, a small body of water connected to House Creek by a small feeder stream. As she was reeling in her first fish, a local variety called drum, a 5-6 foot bull shark suddenly lunged, breaking the surface and taking her catch in one swift flurry of splashing water and hungry shark. Quite a remarkable piece of video (see below).  What makes the video all the more remarkable is its illustration of the bull shark's ability to withstand brackish to near fresh water, which allows it to move up streams and rivers and get into places where you least expect to find...

South Africa’s great white sharks are changing locations – they need to be monitored for beach safety and conservation

South Africa is renowned for having one of the world’s biggest populations of great white sharks (Carcharodon carcharias). Substantial declines have been observed, however, in places where the sharks normally gather on the coast of the Western Cape province. Sharks congregate at these locations to feed, interact socially, or rest.In Cape Town, skilled “shark spotters” documented a peak of over 300 great white shark sightings across eight beaches in 2011, but have recorded no sightings since 2019. These declines have sparked concerns about the overall conservation status of the species. Conserving great white sharks is vital because they have a pivotal role in marine ecosystems. As top predators, they help maintain the health and balance of marine food webs. Their presence influences the behaviour of other marine animals, affecting the entire ecosystem’s structure and stability. Marine biologists like us needed to know whether the decline in shark numbers in the Western Cape indicated changes in the whole South African population or whether the sharks had moved to a different location. To investigate this problem, we undertook an extensive study using data collected by scientists, tour operators and shore anglers. We examined the trends over time in abundance and shifts in distribution across the sharks’ South African range....
