Sharks Breakthrough: Innovations in Porbeagle Research

research_worker from Oregon State University , Arizona State University , and the Atlantic Shark Institute recently print a survey in the diary Frontiers in Marine Science , disclosure groundbreaking findings about the depredation of a pregnant porbeagle shark . The survey use dad - off satellite archival tag ( PSATs ) to proctor the motion of the shark , measurement depth and temperature data to path its behavior . The pregnant porbeagle , measurement 8 foot in length , was detect to have been prey upon by another warm - blood marauder , likely another shark . The research team detect evidence of depredation approximately 5 calendar_month after tag the shark in the mesopelagic Waters near Bermuda , supply the first - ever documentation of depredation on a porbeagle globally.

The survey also foreground the use of two different tag on the shark : a finmount tag attach to the shark 's five for accurate geolocation and a dad - off satellite archival tag for recording depth and temperature . The data roll_up from the tag bespeak a sudden addition in temperature within the shark , propose consumption by a warm - blood marauder . Another porbeagle shark , track for hundred of mile from New England to Bermuda , was also found to have been attack and sink to the ocean floor . The research_worker speculate that the marauder responsible for the attack was likely another lamnid shark , such as a mako or White shark , establish on their body temperature range between 25 and 27 degree Celsius.

The unexpected depredation event shed light on the complex interaction among large shark species , with the research_worker emphasizing the need for foster survey to understand the marauder - prey dynamics in the ocean . The findings underscore the express cognition about the ocean 's top marauder and the importance of continue research to unravel the mystery of Marine ecosystem . The survey 's lead writer , James Sulikowski , foreground the significance of the discovery in disclosure the vulnerability of large shark and the hierarchy of marauder in the Marine environment . This research open new avenue for exploration and underscore the ongoing pursuit to uncover the secret of the ocean 's vertex predators.
