In the Gulf of Alaska, spiny dogfish are the most prominent shark species in the NMFS biennial trawl surveys and annual longline survey. Yeah, yeah, the great white shark gets all the attention. In their native range, redear sunfish prefer warm, large lakes and reservoirs and bayous with vegetated shallow areas and clear water. Because no others had ever been found by scientists, Alec Moore, regional vice chair of the International Union for Conservation of Nature (IUCN) Shark Specialist Group’s Indian Ocean group, says that “some suspected it might be extinct or not a valid species.” In 2008, during a Shark Conservation Society research expedition to Kuwait’s sharq fish market (the name is a coincidence, it means east in Arabic), Moore says that “amongst the many species of whaler shark was one which looked very similar, but different, to a couple of other species.” Later analysis revealed that although this specimen was more than 3,000 kilometers from where Hein caught his, this was a smoothtooth blacktip, the first new individual seen by scientists in over a century.

Destructive fishing activities, pollution and coastal developments can have serious impacts on marine habitats upon which sharks depend. Climate change impacts on the marine ecosystem can also be a cause of concern for sharks, particularly in terms of how population distributions and habitats for sharks, as well as their prey, may be affected , e.g. Fish endocrinology read here When they hunt or attempt to create or tuck into hiding places, they may knock aquarium decor loose and dig under rocks and corals.
