A cage dive with California’s great white sharks

Flashback (Sept. 2002)—A cold chill ran down my spine as I descended into the cold waters of the Pacific.

I may have told myself otherwise, but it had nothing to do with the 56-degree water temperature.

It was all about what lived in the water.

I was in the Farallon Islands, located off the coast of San Francisco, Ca. home of some of the largest great white sharks on the planet.

Specimens there range from 14 to 18 feet long with the occasional 20-footer making an appearance. Although in the safety of a well-crafted steel cage, I felt a sober sense of mortality while gazing into the surrounding sea.

Yes, I was frightened, but also more excited than ever.

After all, this was a dream birthed in childhood and it was now happening in real time.

Before the dive when we reached the islands after a very rough ride across the Pacific, I asked the captain if he needed any help chumming.

“Chumming?” he asked.

“Yes, putting fish oil or blood into the water to attract sharks. I do it all the time shark fishing in the Gulf of Mexico,” I replied.

“We can’t chum here. It’s illegal to chum here in the Farallons. We might start attracting sharks to people,” he said.

A bit dumbfounded, I asked, “Isn’t that the point?”

I then went into a min-lecture of how Jacques Cousteau always had a horse carcass or a huge tuna hanging overboard and that since we paid to see great whites, some chum or at least some bait would be helpful.

“Oh, we have bait. It’s in the long box at the back of the boat,” the captain said.

I quickly walked over and flung the long box open.

“There’s no bait here,” I quipped.

“There’s just a big yellow and red surfboard.”

“That’s the bait. We’re going to pull it behind the boat and the sharks will see it and think it’s a seal,” he said.

Interesting.

The first 30 minutes in the cage did nothing to change my skepticism. Other than the surfboard getting hung up on the cage while they were pulling it like a topwater plug, nothing happened so we moved and had a bite to eat while cruising over to another spot on the island.

Just as a lack sleep turned into drowsiness, the water behind the boat exploded with great fury.

A 15-foot great white grabbed the surfboard and jumped completely out of the water. It spit out the board, then circled and bumped it again. Then another shark from below rocketed out of the water and slammed the board.

I was awake now!

“That’s the coolest thing I have ever seen!,” I exclaimed.

Someone else appropriately said, “We’re going to need a bigger boat.”

The captain motioned for the cage to go in the water and I realized a childhood dream was coming true. The four other people who paid for the expedition opted to stay out of the cage

“Maybe they’re the smart ones,” I thought to myself while descending into cool water.

At one point while submerged, a small school of squid swam up to the cage and swam for a few minutes. Then suddenly they bolted out of the area.

I could have sworn I heard the “Jaws” theme playing as a huge dark shadow moved through the silt below the cage, obscured but obvious that it was something living and very large. When I returned the surface, the captain decided to troll with the surf board some more so the cage was lifted and board deployed.

Within a few seconds, an 18-foot 2,500-pound monster breached the surface and destroyed the surfboard. This shark had some hang time and for a moment we locked eyes.

In “Jaws”,  Capt. Quint talks about whites having dark eyes “like a dolls eyes.”

I agree.

The monster shark and I seemed to make eye contact, if only for a brief second. I could see no conscience or thought, just an instinctive drive to do what sharks do. I was in awe.

The great white shark is nature at its purest and best, no matter how ugly or cruel it might seem to us.

Living in a world where we buy our meat from a market and live in air-conditioned homes, we humans sometimes lose touch with what true survival is all about.

The great white shark embodies that better than any living creature I can think of. More profoundly, it gives us a sense of humility.

Even though mankind has conquered everything from polio to space travel, there are still things to which we are vulnerable; sometimes, we are not at the top of the food chain.

NMFS Sea Turtle Facility

Yesterday our journey through the “Wild Gulf”-our summer long quest to raise awareness to wildlife of the Gulf of Mexico paid a visit to the National Marine Fisheries Service (NMFS) sea turtle facility at Galveston, TX.

Since 1978, the National Marine Fisheries Service (NMFS) has been participating in an international Sea Turtle recovery program. Currently the NMFS Galveston Sea Turtle Facility is participating in a variety of projects including injured and sick turtle rehabilitation, satellite tracking of wild turtles and numerous studies involving Turtle Excluder Devices (TEDs).

We will post more on sea turtles later this month but for now here are some photos from yesterday.

Loggerheads are the most abundant sea turtles in the Gulf of Mexico but that doesn’t mean their populations are healthy. They are down to around three percent of estimated historic levels.

Erin and Abby learned what to do if they find a sea turtle stranded on a beach and were impressed with the amount of effort that goes into conserving these endangered marine reptiles.

Deadly jellyfish found in Texas-Gulf waters!

One of the most dangerous of all sea creatures is the box jellyfish.

They are famously abundant in Australian waters where fatalities are reported on an annual basis.

They are also present in the Gulf of Mexico.

In the Gulf, we have the four-handed box jellyfish, a species I was made aware of by Texas Parks & Wildlife Department (TPWD) biologist Jerry Mambretti in 2014.

“Our gulf sampling crew caught four-handed box jellyfish, Chiropsalmus quadrumanus, a member of the class Cubozoa, in 3 separate trawl samples about 2 miles off McFaddin NWR beach,” Mambretti said at the time.

“Box jellyfish are known for the extremely potent venom produced by some species, including this species, which is normally found in the west Atlantic Ocean, the Gulf of Mexico, and the Pacific Ocean. Their sting is very venomous and dangerous to humans, especially children.”

A study by William Guest noted the species has been known to be abundant in the Matagorda Bay system in the 1950s and their presence has a lot to do with salinity levels..

“The development of a large population coincided with drought conditions and high bay salinities along the Texas Gulf coast. When bay salinities dropped considerably in 1957 the jellyfish disappeared. The jellyfish were found to be living on or near the bottom at all times and preferred areas of soft mud.”

TPWD recommends for most jellyfish stings to splash the area with salt water.

“Then apply a paste of unseasoned meat tenderizer. Don’t press the skin. The pain should go away within an hour. Regular vinegar or a solution of one part bleach to 10 parts water also work to alleviate pain.”

If you think you have been stung by a box jellyfish however seek medical attention immediately. Encounters are rare but the potential for serious problems exist if you do happen to bump into one of these tiny creatures.
