Orcas (or killer whales) are large, powerful aquatic apex predators. There have been incidents where orcas were perceived to attack humans in the wild, but such attacks are less common than those by captive orcas. [1] In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. [2]
The incidents are terrifying for swimmers and surfers alike, but how they can be stopped remains unclear — although scientists think they might have one possible answer. For sharks looking up ...
Port and Starboard are a pair of adult male orcas notable for preying on great white sharks off the coast of South Africa. [1] The duo are identified as having rare and distinct collapsed dorsal fins and they are named for the nautical terms, as Port's fin collapses left and Starboard's collapses right. [2]
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
When they spot sharks or unusual sea life activity, they can warn swimmers to stay on the beach. The tracking program began in 2017 but has taken on new urgency following a rash of shark attacks ...
Offshore orcas feed on sharks and larger fish in deeper water still, rarely, if ever, coming close to the shore. The researchers collected examples and evidence of killer whales traveling even ...
At the time, orcas were not only viewed as costly competition with fishermen for salmon, but as dangerous and threatening to humans as well, and were viewed negatively across the region. In response to these complaints, a machine gun was installed at Seymour Narrows with the intent of killing any orca that passed by.
In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
