Commonly confused with the shortfin mako, the porbeagle shark (Lamna nasus) are fast sharks, with an ability to thermoregulate through their rete mirable. This means that they can retain their speed through heat, even in some of the coldest waters! It’s understandable, since they’re found in some pretty chilly places like Newfoundland.
The fast swimmers take advantage of their speed and consume pelagic schooling fish, other sharks, squid, and even ground fish! But whenever you go after fish like that, there are consequences.. Fishermen often catch these unlucky sharks as bycatch. Not just bycatch, but the second most common bycatch in Norway! They’re also fished commercially for their meat, fins, oil and fishmeal.. Oh, and recreationally on occasion, as if there wasn’t enough trouble for them.
Thankfully they’re a hardy species; Leaving them only vulnerable according to the IUCN.. Although three subspecies are considered endangered, two of which are critical.
