Complex interactions and conflicts between protected populations may challenge the recovery of whole ecosystems. Several factors indicate that white sharks may be currently limiting the recovery of California sea otters.
Protected white sharks (Carcharodon carcharias) and pinnipeds have an established predator–prey relationship along the California coast.
The great hammerhead shark is categorized as “critically endangered” by the International Union for Conservation of Nature. That’s the designation just before “extinct in the wild.” The species is highly threatened with extinction.

As whale sharks assemble in coastal regions to spend substantial time in surface waters, experts theorised collisions with ships could be causing substantial whale shark deaths. Previously, there was no way of monitoring this threat.
Scientists from 50 international research institutions and universities tracked both whale shark and ship movements across the globe to pinpoint areas of risk and potential collisions. Satellite-tracked data from nearly 350 whale sharks was submitted to the Global Shark Movement Project, conducted by MBA researchers.
A neonate (newly hatched) ghost shark was found in the net during a trawling survey at about 1,200 metres below sea level. The survey had been conducted by NIWA to estimate the population of blue grenadier (hoki fish) at the Chatham Rise, off New Zealand’s South Island.
Florida International University (FIU) marine scientist Yannis Papastamatiou, Ph.D. candidate Sarah Luongo, and a collaborative team of researchers wanted to uncover some of the mysteries of the white sharks (Carcharodon carcharias) that gather seasonally around Guadalupe Island, Mexico.
So, your dive goal is to get up close and personal with several different species of shark—in one day of diving. Well, then I suggest you fly to Jupiter.
Small, antibody-like proteins known as VNARs (Variable New Antigen Receptors) are derived from the immune systems of sharks, and appear to be extremely potent in preventing Covid-19, as well as its variants, and related coronaviruses from infecting human cells.
The ban does not apply to people with permits issued by the state Department of Land and Natural Resources (DLNR), shark fishing for public safety, sharks captured for self-defence, or sharks taken outside of state marine waters with required documentation.
According to Act 51, the conditions of non-commercial permits for the take of sharks “shall include native Hawaiian cultural protocol, size and species restrictions, and a prohibition on species listed as endangered or threatened.”
