Video: free-swimming great hammerhead shark tagged off Bimini

YouTube user GrantJohnsonMD has posted a video of a free-swimming great hammerhead (Sphyrna mokarran) being tagged off of Bimini, Bahamas. The shark is described as a 12′ female and was tagged with a with a NMFS dart tag, which will help with research purposes to better understand the species, which is listed as “endangered” on the IUCN redlist.

The video description points out that the shark was tagged while free-swimming (as opposed to a catch and release tagging) in order to reduce stress on the animal. As can be seen in the video, the shark does not seem to be fazed by the tagging process. She remains in the area after being tagged and continues to show interest in the hang bait.
