Basking shark (Cetorhinus maximus) Second largest species of shark in the world, but this shark is a filter feeder and not a predator. It can be mistaken for the great white owing to similar coloring, but has gill slits that slash almost around its whole head and has a front dorsal fin that is more triangular than the raked shape [ 12 ] found ...
Ubiquitin carboxyl-terminal hydrolase 2 is an enzyme that in humans is encoded by the USP2 gene. [ 5 ] [ 6 ] Ubiquitin (MIM 191339), a highly conserved protein involved in the regulation of intracellular protein breakdown, cell cycle regulation, and stress response, is released from degraded proteins by disassembly of the polyubiquitin chains.
Researchers have discovered evidence pointing to the first known case of a porbeagle shark — which can grow up to 12 feet long and 500 pounds — being killed by a large shark predator.
A mysterious shark that may count as the world’s largest predatory fish appears to be in decline off the U.S., prompting a rush to gather as much information as possible about the secretive ...
Porbeagle shark was eaten by a warm-blooded predator, team says. Sulikowski said the team put two different tags on their subject sharks. The first tag, called a finmount tag, is located on the ...
Hemiscyllium sharks of the family Hemiscylliidae are also known as walking sharks [1] and Epaulette sharks.These small, nocturnal, benthic dwelling swimmers have evolved to be able to 'walk', or use their fins to propel themselves over rocks, into pools, or into small crevices in their habitats.
As Cretoxyrhina inhabited oligotrophic and pelagic waters where predators such as large mosasaurs like Tylosaurus and macropredatory fish like Xiphactinus were common, it is likely that it also was an r-selected shark, where many infants are produced to offset high infant mortality rates.
Shocked researchers are trying to figure out what kind of apex predator took out an 8-foot-shark as it wandered through the oceans — and they think it might have been another, bigger shark.
