Flower Garden Banks – A Manta Ray Nursery

MANTA RAYS ARE FOUND IN OCEANS WORLDWIDE, BUT MANTA RAY JUVENILES ARE RARELY SEEN. Except, it develops, in the newly recognized manta ray nursery in the Gulf of Mexico’s Flower Garden Banks National Marine Sanctuary. When visiting manta specialist Josh Stewart told Flower Gardens staff he had spotted only the second juvenile he had ever seen, their response was: they see them all the time. Apparently, they assumed the smaller mantas were a different species

Haunting Video of a Stray Narwhal Adopted by Belugas

YOUNG WHALES ARE SOMETIMES KNOWN TO WANDER, but a lone, stray narwhal has apparently wandered into a pod of young beluga whales – and stayed. And  been accepted as one of the boys. The narwhal – identified by his iconic long tusk and gray-spotted body – has apparently been swimming with the white-bodies belugas in the St. Lawrence River for the past three years. The setting is far south of narwhals’ usual habitat in the

Whale Shark Size And Age: Long Live Whale Sharks!

APPARENTLY IT TAKES TIME TO GROW TO BE THE WORLD’S BIGGEST FISH. A new study of whale shark size and age has indicated that gargantuan fishes can live to the ripe old age of 130 years. Marine biologists at the U.K.-based Maldives Whale Shark Research Programme and Florida’s Nova Southeastern University analyzed a decade’s worth of repetitive, non-invasive underwater measurements of whale sharks in the Maldives to understand whale shark age and growth details.

The Shark Pup Hatching, from bioGraphic

HERE’S A REMARKABLE PHOTO OF A SHARK PUP HATCHING, published in the terrific science magazine bioGraphic. It’s a small spotted catshark (Scyliorhinus canicula), caught just after its emergence from its egg casing. That’s its name – small spotted catshark – but the little shark has other common names, including lesser spotted dogfish. Recreational diver are not so likely to see one.

Here’s to Eugenie Clark – and “Genie’s Dogfish!” 

A NEWLY IDENTIFIED SPECIES OF SHARK has been named “Genie’s Dogfish” in honor of renowned marine biologist Eugenie Clark, a.k.a. the “Shark Lady.” It may be just coincidence that the news about “Genie’s Dogfish” came out just when the cable networks have resumed telling us that it’s totally unsafe to be in any ocean with any shark. But it’s fitting. Dr. Clark, who died in 2015 at age 92, was a pioneer in shark research

Rats and Reefs: What Happens On Land Doesn’t Stay On Land

A NEWLY PUBLISHED STUDY ON THE LINK BETWEEN RATS AND REEFS has found a substantial link to the health of the coral reefs in the waters around the islands.  The reason: Seabird poop on land is good for a broad range of reef denizens underwater. And the rats kill off seabirds, whose guano provides nutrients that enhance the reef’s health. An international team of scientists studied the ecosystems of rat-infested and rat-free islands in the Chagos
