A battle-scarred nice white shark has been caught on video after an unimaginable 1,100-mile journey – a discovery that scientists say has “major implications” for the research of the notorious species.
The younger male is roofed in chew marks – probably the work of one other shark – and was seen off the coast of Mozambique.
Identified from its facial scars and a tag, the lethal predator was captured on movie utilizing a particular baited distant underwater video digicam (BRUV).
The large fish was matched to a shark sighting off Struisbaai, South Africa, in May 2022 – which means this younger nice white had gone on a 1,100-mile voyage this yr.
The analysis was led by the Wildlife Conservation Society (WCS) and the Instituto Oceanografico de Mozambique (InOM), who’re conducting surveys to evaluate shark and ray populations off the coast of southern Africa.
Rhett Bennett, half on the BRUV survey venture in Mozambique mentioned: “This single observation is of great value to shark science and conservation, as it confirms a transboundary movement, on the scale of thousands of kilometres, of a threatened shark species, which has major implications for the management of this species.
“The particular person ID match additionally highlights one more worth of BRUVs, and particularly video information, as helpful analysis instruments for shark and ray science.”
Mr Bennett informed Newsweek that the marks on the shark’s face had been probably brought on by a tussle with one other shark.
Great white sharks can develop to greater than six metres lengthy and dwell for 70 years or extra – and swim at speeds of 16mph.
While the species is accountable for extra recorded bites on people than every other shark, specialists don’t imagine they aim people.
Instead many scientists imagine that mistaken identification is commonly an element, notably in areas of low visibility.

The findings of the BRUV digicam surveys will assist to tell fisheries and useful resource managers in South Africa and Mozambique concerning the migratory capability of white sharks, and the necessity for multilateral or no less than bilateral administration measures for this and different threatened shark and ray species which might be transferring between the waters of those nations.
Alison Towner, a part of the white shark tagging research in South Africa mentioned: “This important ID match and confirmation of transboundary movement has come at a time that the Southern African white shark population is facing the additional threat of orca predation on top of other anthropogenic threats such as shark nets.
“It’s an amazing instance of collaboration between completely different analysis platforms.”
