Undeniably the shark movie to end all shark movies, the 1975 blockbuster, Jaws, not only smashed box office expectations, but forever changed the way we felt about going into the water – and how we think about sharks.
A team of marine scientists has confirmed that southern Africa’s most threatened endemic shark – the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) – has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles).
A new study shows that the gigantic Megalodon or megatooth shark, which lived nearly worldwide roughly 15-3.6 million years ago and reached at least 50 feet (15 meters) in length, gave birth to babies larger than most adult humans.
A new study shows that the body size of the iconic gigantic Megalodon or megatooth shark, about 50 feet (15 meters) in length, is indeed anomalously large compared to body sizes of its relatives.
Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape. The results illustrate how these sharks evolved into highly specialised, exclusively bottom-dwelling ambush predators and thus also contribute to a better understanding of their threat from environmental changes.
