Great Whites of the Gulf

The eyes.

Coal black.

Intense.

Ominous.

There is something powerful about the eyes of a great white shark.

In the 1975 blockbuster “Jaws”, obsessed shark hunter Capt. Quint describes them as “lifeless eyes…black eyes…like a doll’s eyes”.

As an 18 footer turned its eye to look at me while on a cage diving expedition to the Farallon Islands I quickly disagreed with Quint. Black they were but lifeless the sharks’ eyes were not.

They were filled with purpose. To kill. To eat. To survive.

Long believed extinct in the Gulf of Mexico or at least an extremely rare visitor, it seems there are survivors.

In 2014, “Katharine” and “Betsy”, two young great whites were verified in Gulf waters.

Both of these sharks were fitted with SPOT transmitters by research/conservation group OCEARCH. These tags communicate with satellites and when the information from those tags if fed back to OCEARCH, it allows the public to view their movements at OCEARCH.org.

When, Katharine, all 2300 pounds of her, staked out the stretch of coastline off of Panama City Beach, Fla., people paid attention. More than four million logged onto the OCEARCH website, crashing the server the week and causing a media firestorm.

“Those two sharks, Katharine in particular, drew an enormous amount of attention to great white sharks in a very positive way and the interactive nature of the site, gave people a way to see great white movements take place in a way never before possible,” said OCEARCH founder Chris Fischer.

“We are solving the life history puzzle of ‘Jaws’ out of the Cape Cod area for the first time in history and it has been interesting to see unfold.”

Cape Cod is one thing but the Gulf of Mexico? That’s the domain of bull sharks and black tips, not great whites. Right?

Wrong.

Great white populations are on the rise due to 20 plus years of gill nets being banned along the Atlantic and Gulf Coasts. These nets caught and killed many juvenile great whites that are born on the East Coast and migrate into the Gulf to feed.

The shallow, nearshore areas along the eastern seaboard and portions of the Gulf Coast, especially Florida are “nursery” areas where the younger sharks spend their time. Both Katharine and Betsy were tagged off of Cape Cod in August 2013 and covered thousands of miles of water before entering the Gulf.

In 2005 I wrote an article called “Jaws in the Gulf” for Tide magazine recalling historical references and at the time a recent sighting. The article was a bit controversial as great whites in the Gulf seemed too magnificent to believe.

Now it has been vindicated. But that’s not the point. Seeking out the mysterious is a big part of what we do.

The point is the most iconic shark in the planet is proven to inhabit the Gulf and could be on the rise. Fishermen and conservationists need to know so these great predators can be protected.

NOAA has some extremely interesting older data on great whites in the Gulf of Mexico. Their earliest recorded white shark was off the coast of Sarasota, Fla on a set line in the winter of 1937. Another specimen was caught in the same area in 1943.

In February 1965, a female was captured in a net intended for bottlenose dolphins at Mullet Key near St. Petersburg. In addition, National Marine Fisheries Service officials reported 35 great whites as bycatch in the Japanese longline fishery in the Gulf from 1979 through 1982.

Those sharks died but last year the first great white ever known to be caught from the surf was taken by an angler in Panama City Beach, Fla.

Instead of killing it, he fitted it with a tag, photographed and released it.

Knowing about great whites, their rarity and conservation problems is crucial so great whites meet happy endings when encountered by anglers-the user group most likely to see them.

It might seem counterintuitive to save something that can and occasionally does eat humans. But the fact is we need things like great white sharks to keep us humble, to remind us, we are vulnerable and to keep us in a sense of wonder.

That was the state I was in gazing out onto the Gulf of Mexico while fishing the 61st St. Pier in Galveston, TX with my Dad at age 12.

“It’s a shame we don’t have a lot of great whites off our coast,” I told him.

“Maybe we do. We just haven’ found them yet,” Dad replied.

Dad is gone now and I sure would like to tell him, they have been found. Great whites dwell the Gulf of Mexico and you never know. There might have been one cruising the surf just beyond that pier on that night so long ago.

It is entirely possible.

Manta Ray found just off TX beach (Video)

Last week readers Andy Allen and Reggie Begelton captured this video of a large manta ray swimming a mile west of the Sabine Jetties, just off the beach at Sea Rim State Park out of Sabine Pass, TX.

Manta rays are present in the Gulf of Mexico but sightings are rare and sightings with a mile of the beach are virtually unheard of in Texas.

According to Wikipedia, swimming behavior in mantas differs across habitats: when travelling over deep water, they swim at a constant rate in a straight line, while further inshore they usually bask or swim idly around. Mantas may travel alone or in groups of up to 50. They may associate with other fish species as well as sea birds and marine mammals. Mantas sometimes breach, leaping partially or entirely out of the water. Individuals in a group may make aerial jumps one after the other. These leaps come in three forms: forward leaps where the fish lands head first, similar jumps with a tail first re-entry or somersault. The reason for breaching is not known; possible explanations include mating rituals, birthing, communication, or the removal of parasites and remora.

“Manta rays have broad heads, triangular pectoral fins, and horn-shaped cephalic fins located on either side of their mouths. They have horizontally flattened bodies with eyes on the sides of their heads behind the cephalic fins, and gill slits on their ventral surfaces. Their tails lack skeletal support and are shorter than their disc-like bodies.  The dorsal fins are small and at the base of the tail.”

“The largest mantas can reach 1,350 kg (2,980 lb). In both species the width is approximately 2.2 times the length of the body; M. birostris reaches at least 7 m (23 ft) in width while M. alfredi reaches about 5.5 m (18 ft). Dorsally, mantas are typically black or dark in color with pale markings on their “shoulders”. Ventrally, they are usually white or pale with distinctive dark markings by which individual mantas can be recognized. All-black color morphs are known to exist. The skin is covered in mucus which protects it from infection.”
