Diving with Sharks – an Interview with Brian Skerry

Brian and his crew dove off the coast of Rhode Island in July. The pictures here were taken during that dive. Brian gave us some of his impressions from that dive, and from diving with sharks in general.

 

Robin: How common is it for you to come across sharks when you’re diving in New England?

Brian: I would say it’s extremely rare to find them on a regular dive. When we are looking for sharks, we go to the places where we’ve looked at ocean currents, water temperature, topography, and it’s our best hypothesis as to where they might be.

Robin: Have you ever had any shark encounters in New England that gave you pause?

Brian: Not as a rule, no. I’ve been diving with sharks in New England for over 25 years. I have to say that, for the most part, they’ve always been very polite. I’ve not had many dicey encounters. Certain species give you more pause than others. For example, I love diving with makos, but they have a very different behavior than other sharks. They come in appearing to be more agitated. They’re much more hyper and jacked up. They test things with their mouths. So it’s not uncommon to have one come over and bite your camera or something else you’re holding. Makos are a serious predator in the ocean – they can get very large. I’ve really only been in the water with small to mid-size ones, if a big one came along I would get out.

Robin: Do you find makos often?

Brian: Historically, no, but in recent years I’ve been working with a friend of mine, Joe Romeiro, who is very good at finding them – so the success rate has increased. We’re going to different places and putting in the effort.

Probably 80% of the times we look for them we find them. But sometimes they don’t stick around.

Robin: The blue sharks in your pictures seem interested in you.

Brian: Blue sharks are very curious. Like any other animal or people, they have personalities. Some are shy and timid. Others start off that way but build up some curiosity. Blue sharks are, of course, apex predators. They can get pretty large – up to 12 feet and pretty beefy – but my experiences with them have been just wonderful. Blue sharks are probably my favorite in many respects. They are pelagic animals, and they cover great distances each year, but they are very elegant. They look like an aircraft. Long slender fuselage-like body, long wing-like pectoral fins, deep blue beautiful color.

Robin: Is it common for the blue sharks to be hanging out at the surface like they are in these pictures?

Brian: The water below us was a couple hundred feet deep, and they were on the surface when we were there, but they feed in the entire range of depth. They can be down deep feeding on squid but also come up to the surface. I have been out at sea and seen them up on the surface, and have seen them when I was decompressing after dives on the Andrea Doria.

They’re a very elegant, usually relaxed kind of shark. I’ve had nothing but great encounters with them.

Robin: Let’s talk about the shark with the hook and the one with the plastic. Is this a common sight when you dive?

Brian: It’s very common to see this. More common than not these days. At least 90% of the blue sharks we see these days have some kind of evidence of fishing activities. It’s very difficult to find a clean animal. The day I made those pictures there were five sharks and only one was clean.

The plastic hoop on this blue shark is from a bait box. Fishermen have cardboard boxes of bait with these plastic hoop straps on them on their boats. As the bait thaws the box gets mushy and the strap falls off. Then it gets thrown overboard and can get wrapped around an animal.

We want to try to help them but it’s hard to catch them. Sometimes it’s possible to physically catch the shark with a big net when the shark comes close to the boat, and bring it on deck and hold it down to snip off a hook or leader.

Robin: Have your feelings about sharks changed over your diving career?

Brian: Oh yeah, absolutely. I think when I first started 35 years ago I was always very interested in sharks, but it was more of a fascination. I just wanted to see one and get close to it. In subsequent years my admiration for them has only grown, simply because I realize just how perfect they are. They have remained unchanged for 300-400 million years, because they haven’t needed to change. I’ve grown a lot more aware of shark conservation issues because100 million sharks are being killed every year and the health of ocean is tied to having healthy populations of these apex predators. Now I try to make pictures that celebrate these magnificent creatures and shine a new light on them. But I also make pictures that show the animal that is being killed at alarming rates.

I continue to respect and admire them, but also want to show people the problems.

Robin: Have you noticed a change in the attitudes of other people?

Brian: I have noticed people’s attitudes changing over time. When I first started diving in the 70s, among scuba divers, sharks were demonized. Nobody wanted to see a shark – it was the worst thing you could imagine. Today divers go on dive trips to see sharks. They pay lots of money to travel places in the world where they can see sharks.

I still think there’s a big part of the population that has a lot of misinformation about sharks – monsters to be afraid of. But I think it’s beginning to change a little bit. As good information about sharks permeates popular culture things may start to change.

Are you ready for some sharks?

We are excited to bring you some amazing new pictures from Brian Skerry this week. Brian has been diving all summer off the coast of Massachusetts and Rhode Island so we can show you some of our biggest fish. This week we will not only be showing you these pictures but also bringing you an exclusive interview with Brian about his shark diving experiences, and his thoughts on shark conservation. There will be tons of shark stories, shark pictures, and shark love this week. So come back tomorrow and meet some of your saltwater neighbors!

Atlantic Wolffish – Cool as Sharks, Hotter than Shark Week

Categories: Creature Features

Some people are enraptured by the fearsome predatory nature of sharks. The image of the omnipotent king of the seas, roaming the deep and preying on any hapless creature small or large, holds a permanent niche in the American psyche. Sharks are cool, there is no doubt. Just look at the media celebration known as Shark Week, which happens every summer. Don’t worry, we get shark fever too, and Brian Skerry has some incredible new shark photos, which we’ll be debuting soon.

 

However, let’s not allow the annual shark-mania to block out the real glamour of other denizens of the deep, which reside at Cashes Ledge and in other spots across the Gulf of Maine. My favorite creature is the Atlantic wolffish, also known as the sea wolf. (This animal is so cool they named a whole class of attack submarines after it and the sports teams at a New England college.) If there is an animal that illustrates both the wonderful diversity of New England’s ocean and the need for protecting habitat for ocean wildlife, it is the Atlantic wolffish. If there is a special place in New England’s ocean worthy of providing better and more permanent protection it is Cashes Ledge.

 

We’ve talked about these toothy fish before, but they merit lots of discussion given how important they are to our Gulf of Maine ecosystem and how much they need our protection. Atlantic wolffish population numbers have taken a perilous decline since the early 1980s. The threats from commercial fishing practices – especially bottom trawling gear –has not only decimated wolffish populations but destroyed the type of rocky underwater habitat which they depend upon. For a species that absolutely needs rocky outcrops and small cave-like structures, the impacts to their habitat are particularly harmful.

 

By 2006, Atlantic Wolffish populations across the Gulf of Maine had declined to a point where serious action was needed. Then the Conservation Law Foundation and Dr. Erica Fuller prepared and filed a petition to protect the wolffish under the Endangered Species Act in 2008. The petition received enough attention for this “gruesome fish” that the National Marine Fisheries Service eventually placed a complete restriction on harvest and possession of Atlantic wolffish across the North Atlantic. This falls short of the full protection warranted under the ESA, but since the wolffish can be successfully caught and released, this temporary fishing regulation gives the wolffish population enough limited protection to recover while further studies are done.

 

The rocky slopes of Cashes Ledge provide excellent habitat for the wolffish, and Cashes Ledge is an even more important area since the destructive bottom trawling gear has been banned year-round there since 2002 through fishery management regulations put into place by the New England Fishery Management Council.

A Tale of Two Cod

The almighty cod – the most legendary fish in our New England waters. Atlantic cod is greyish-green, and a renowned dweller of the Gulf of Maine. It is a staple of our traditional cuisine and a historic driver of our economy. You‘ve seen an Atlantic cod, right? But have you ever seen a red Atlantic cod?

How the red cod got its color is a mysterious tale, and one that even dedicated Gulf of Maine fish researchers don’t fully understand yet. Red cod live throughout the North Atlantic, in discrete populations. The red cod you see in these photos, pictured along with the traditionally colored “olive cod,” live on Cashes Ledge, about 80 miles off the coast of Gloucester, Massachusetts. They are the same species of fish, but they don’t fraternize much. The red cod and olive cod seem to be on different reproductive schedules. They also eat different things and have different ranges. Olive cod like to wander around the North Atlantic, but red cod tend to hang out in one place – “shallow, kelpy habitats,” according to Graham Sherwood, Research Scientist at the Gulf of Maine Research Institute in Portland, Maine. Shallow and kelpy is just where Brian Skerry found these red cod – in fact, in about 40 feet of water. Well, it was shallow for cod, anyway.

Why are they red? The food red cod eat, things like crabs, lobsters, and worms, are high in carotenoids – naturally-occurring chemicals which give the fish the ability to turn red. Not all cod that eat these things turn red, though – deeper dwelling olive cod remain traditionally cod-colored even on a high-carotenoid diet. Sherwood speculates that there might be an adaptive advantage to the red coloring for shallow-living cod. Perhaps the shallow water cod need better U/V protection. Or, more likely, it makes it easier to hide in all that red kelp.

There haven’t been any studies yet to indicate whether or not red cod are genetically distinct from olive cod. It’s possible that a red cod and an olive cod could come from the same parents, but be different in appearance and behavior due to having hatched in different habitats. One deeper and darker, one shallower and kelpier. Possible, but unlikely, says Sherwood. He thinks that, while they are the same species of fish, they may be genetically different enough to look and behave distinctly from each other. Maybe different populations of cod began spawning at different times, to take advantage of optimal environmental conditions, and over time they differentiated into the red and olive types. But, nobody knows for sure yet.

The color and habitat preference aren’t the only differences between the cod. Red cod are less streamlined than olive cod – no need to be shaped like a sports car if you’re just going to hang out in the garage. They also have shorter snouts than olive cod. Although, says Sherwood, if it weren’t for the color difference you would have a hard time telling them apart. Maybe because these fish tend to be homebodies, hanging out in remote places like Cashes Ledge, or in shallow inshore waters that are not targeted by fisheries, we’re less likely to run into them. Brian, a 35 year veteran of diving in the Gulf of Maine, says they are unlike anything he has ever seen.

The red cod are just one example of the amazing biological diversity that is found at Cashes Ledge. We can’t wait to show you more as our Ocean Odyssey continues!
