Rising demands for shark products has increased pressure on shark fisheries, but little monitoring or management occurs of most fisheries. [7] Major declines in shark stocks have been recorded over the past few decades; some species had declined over 90% and population declines of 70% were not unusual by 1998. [ 8 ]
Shortfin mako sharks consumed 4.3% to 14.5% of the available bluefish between Cape Hatteras and Georges Bank. [22] Shortfin mako sharks over 3 m (9.8 ft) have interior teeth considerably wider and flatter than smaller mako, which enables them to prey effectively upon dolphins, swordfish, and other sharks.

The longfin mako shark (Isurus paucus) is a species of mackerel shark in the family Lamnidae, with a probable worldwide distribution in temperate and tropical waters. An uncommon species, it is typically lumped together under the name "mako" with its better-known relative, the shortfin mako shark (I. oxyrinchus). The longfin mako is a pelagic ...
As of December 2019, the International Union for Conservation of Nature (IUCN) listed 223 critically endangered avian species, including 19 which are tagged as possibly extinct or possibly extinct in the wild. [1] [2] 2% of all evaluated avian species are listed as critically endangered. No subpopulations of birds have been evaluated by the IUCN.
Researchers expect a smaller shark to fall prey to bigger sharks, but one measuring 8 feet was pretty unexpected, he said. The fact that this happened is a testament to how little is known about ...
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In December 2019, the International Union for Conservation of Nature (IUCN) listed 460 endangered avian species. [1] Of all evaluated avian species, 4% are listed as endangered. No subpopulations of birds have been evaluated by the IUCN.
In some cases — bull sharks, mako sharks and baby sand tiger sharks, ... Porbeagles, which have historically been overfished, are considered endangered in certain parts of the world. Given they ...
Some scientists have argued that proposing to kill sharks to stop depredation is missing the point, noting that overfishing of shark’s prey species can cause them to bite fish already on someone ...
