Grenland: Pronađen morski pas star 512 godina

U vodama oko Grenlanda pronađen je morski pas koji bi mogao biti star između 272 i 512 godina. To znači da je došao na svijet u 16 stoljeću.

Ovaj morski pas je vjerovatno najstariji živi kralježnjakna planeti. Pripada vrsti grenlandskih morskih pasa koji su poznati po dugom životnom vijeku, a starost im se određuje dužinom.

In exactly 1 hr and 7 minutes a satellite tag will pop-off from this Greenland shark female, it will float to the surface and establish contact with an Argos satellite. It will then transmit information on position as well as occupied temperatures the past 3 months. By tomorrow morning I will hopefully have the data which just can make it into my PhD before ending in four weeks. All of this (except handing in PhD in four weeks) will however only happen IF 1) the shark is not under sea ice (which would inhibit satellite transmission), 2) the sea is not too rough where the shark is which could lead to that the tag cap can’t be exposed properly in the air or 3) that the shark has not been deeper than 2,000 m which would have crushed the tag and destroyd it…. it also requires that there is no annoying animal eating the tag before we get the data which happened to us on a previous deployment.

Naime, morski psi ove vrste godišnje rastu po jedan centimetar. Dob životinje objavljena je u časopisuScience, a ovo je najstariji primjerak od 28 morskih pasa koje su naučnici proučavali.
