Volunteers work to herd Atlantic white-sided dolphins found Friday in Wellfleet, Massachusetts, into deeper water
More than 100 dolphins have become stranded in the shallow waters around Cape Cod on Friday in what an animal welfare group is calling βthe largest single mass stranding eventβ in the organizationβs 25-year history.
A group of Atlantic white-sided dolphins were found Friday in Wellfleet, Massachusetts, about 100 miles south-east of Boston, in an area called the Gut β or Great Island at the Herring River β which experts have said is the site of frequent strandings, due in part to its hook-like shape and extreme tidal fluctuations.

Swimmer off Fernandina beach was rescued by Nassau county marine unit after distress call from boat on Friday
A shark attack off Floridaβs Atlantic coast left a man with a βsevere bite to his right armβ on Friday, authorities say, leaving him in critical condition from blood loss.
The Nassau county sheriffβs office marine unit, which was patrolling off the coast of Fernandina beach near the Florida-Georgia border, said it had received a distress call from a boat on Friday and had applied a tourniquet to stop the bleeding.

From its sprawling HQ in Tennessee, Mars is courting the next generation of high-spending pet owners
Prom Week has arrived in Tennessee, and the class of 2024 is lined up in suits and crowns, posing for pictures by the red carpet. Who says four legs and a tail should stop you from going to the ball?
Itβs just another day in doggy daycare. As well as a graduation ceremony, canines at this facility in Franklin, Tennessee, on the outskirts of Nashville, were recently treated to bark-uterie β customized charcuterie boards β and challenged by Sports Week, for which they were dressed up with sweatbands.

The humble hagfish is an ugly, gray, eel-like creature best known for its ability to unleash a cloud of sticky slime onto unsuspecting predators, clogging the gills and suffocating said predators. That's why it's affectionately known as a "snot snake." Hagfish also love to burrow into the deep-sea sediment, but scientists have been unable to observe precisely how they do so because the murky sediment obscures the view. Researchers at Chapman University built a special tank with transparent gelatin to overcome this challenge and get a complete picture of the burrowing behavior, according to a new paper published in the Journal of Experimental Biology.
βFor a long time weβve known that hagfish can burrow into soft sediments, but we had no idea how they do it," said co-author Douglas Fudge, a marine biologist who heads a lab at Chapman devoted to the study of hagfish. "By figuring out how to get hagfish to voluntarily burrow into transparent gelatin, we were able to get the first ever look at this process.β
As previously reported, scientists have been studying hagfish slime for years because it's such an unusual material. It's not like mucus, which dries out and hardens over time. Hagfish slime stays slimy, giving it the consistency of half-solidified gelatin. That's due to long, thread-like fibers in the slime, in addition to the proteins and sugars that make up mucin, the other major component. Those fibers coil up into "skeins" that resemble balls of yarn. When the hagfish lets loose with a shot of slime, the skeins uncoil and combine with the salt water, blowing up more than 10,000 times its original size.
