North Myrtle Seashore vacationer Lillian Carter captured this excellent video of a dolphin enjoying offshore of our coast.
The video was uploaded to Fb on January sixteenth.
It is not uncommon for dolphins to be seen off the coast of the Grand Strand in January and February.
Based on Biosphere on-line:
Bottlenose dolphins of the USA migrate up and down the Atlantic coast, heading north within the spring, and south once more within the autumn. The seasons are an element, it appears, however how precisely do the dolphins know when to make their migratory transfer?
New findings from the College of Georgia counsel that bottlenose dolphins (Tursiops truncatus) use water temperature as their cue to show round and start the lengthy journey within the different course. These water temperatures are affected by situations centered round North Myrtle Seashore climate for these enjoying offshore.
Over 1000 dolphins have been recognized and their each transfer was tracked. They have been recognised by their dorsal fins, as every one is totally distinctive in form and so they additionally develop attribute scratches and notches over time. Identical to a human fingerprint, these options permit identification of particular person dolphins, so every dolphin may very well be tracked all through their migrations.
The researchers discovered that dolphins tended to start migration when water temperatures dropped, shifting south to hotter waters. It’s nonetheless unclear whether or not the transfer south is just for heat, or whether or not it is because of different components, resembling elevated numbers of prey.
The quantity of salt within the water additionally affected whether or not dolphins hung round – the dolphins have been at their lowest abundance when salinity was excessive.
