Jumping the shark: New study reviews the breaching behavior of sharks and rays

September 19, 2024September 20, 2024 David Shiffman

One of the most iconic images of shark behavior is a great white shark hitting its prey so hard from below that the whole shark flies out of the water. This behavior, called “breaching,” has been documented in many species, and is useful for a variety of ecological functions, not just hunting. I spoke to … Read More “Jumping the shark: New study reviews the breaching behavior of sharks and rays” »

It’s a special Friday morning edition of Thursday Afternoon Dredging because I was traveling! Cuttings (short and sweet): Follow Nova the White Shark, a great white shark tagged in Canada by OCEARCH, on twitter! The day after Nova was tagged, I spent a day with the OCEARCH team- check out this Facebook live interview. … Read More “Angry Canadian Crabs and Extinct Australian Sea Stars: Thursday Afternoon Dredging, September 27(8)th 2018” »

Have you heard the good news about shark populations? Shark population increases are cause for #OceanOptimism

February 28, 2018February 28, 2018 David Shiffman

Conservation, Science

Did you know that some shark populations have declined due to overfishing? Did you know that some once-declined shark populations have recovered? If you’re like my twitter followers, it’s likely that you’ve heard the bad news, but have not heard the good news.

Why does this matter?
It’s important to share bad news so that people know there’s a problem, and that we need to act to solve that problem. However, it’s also important to share good news so that people know that a problem is solvable! This idea was behind the birth of the #OceanOptimism online outreach campaign.

Go shark diving with OpenROV Trident and maybe get a bit too close an personal with a great white shark.

Yes, that is the esophagus of a great white shark, in the wild. No, you should not attempt to replicate this experience.

#IAmSeaGrant. Despite being one of the most bipartisan research programs in the United States, with a huge return on investment for coastal communities and businesses, Sea Grant is under attack from the current administration. Deep Sea News has been collecting stories from marine researchers who’ve benefited from Sea Grant programs: Ben Wetherill, Nyssa Silbiger, and Christy Bowles.

Bioshock Oceanographic: How deep is Rapture?

February 11, 2015February 17, 2015 Andrew Thaler 5 Comments

Popular Culture, Science

“To build a city at the bottom of the sea! Insanity. But where else could we be free from the clutching hand of the Parasites? Where else could we build an economy that they would not try to control, a society that they would not try to destroy? It was not impossible to build Rapture at the bottom of the sea. It was impossible to build it anywhere else.”

Andrew Ryan, Bioshock

Rapture, a city beneath the sea, the crowning achievement of Randian industrialist Andrew Ryan. This atmospheric world of technological wonder and urban decay serves as the setting for one of the greatest video games of all time, Bioshock. The player, finding themselves stranded at sea in a fiery plane crash, makes their way towards a lonely lighthouse, descends into the sunken, desolate city, and unlocks the mysteries surrounding the creation and destruction of a most unusual city.

Though many questions are answered as the player journeys into the heart of Rapture, collecting audio diaries of its residents along the way, one question still eludes: How deep is Rapture and where, exactly, is it?

What Jaws Teaches Us About Scientists and the Future of Shark Bite Politics

Dr. Christopher Neff is a Lecturer in Public Policy in the Department of Government at the University of Sydney. He completed the first PhD on the “Politics of Shark Attacks” and has been published in Marine Policy, Coastal Management and the Journal of Homosexuality.

Jaws is a great horror movie. Personally, it’s one of my favorites. Politically, it kills me. While it has certainly inspired generations of marine biologists, researchers and social scientists (like me) since its release in 1975, it has also served as the most powerful vehicle to advance public fear of sharks in modern history. These two different implications become problematic because while sharks make for great movies, movies make for lousy public policy. When tragic shark bite incidents occur, there is a classic Jaws-esque analogy just waiting to be made. And sometimes the media circus turns into policy.

I recently wrote an article called “The Jaws Effect” for the Australian Journal of Political Science comparing policymaking in Western Australia and the movie Jaws. While, we see some of these comparisons in real-time the reason it is important to study this formally is because these moments can tell us about the tensions between politicians and scientists that lead to myth-based policies.

Agents of seal: stealthy seals use subsurface structures to sneak by sharks

Predators are highly influential in ecosystems because of the many top-down effects they can have. The most obvious and direct way predators influence an ecosystem is by eating and reducing the number of prey animals in the system, but another equally important way is the indirect influence they have on the behaviour of prey animals.

If you have avoided parking on a risky-looking street, taken a different route between classes to avoid a bully, or abandoned a forest hike because of snapping twigs in the distance, you have been indirectly affected by perceived ‘predators’. In the wild, prey animals will also change their behaviour when they perceive that predators are around, and these altered behaviours often influence other species, ultimately shaping the ecosystem.

Animal movement is often shaped by natural barriers; a fish can’t leave the river it swims in, a tortoise is going to struggle to climb a cliff face, and a pangolin can’t swim across the sea. These barriers come quite naturally to the animals, yet researchers have often struggled to account for these constraints in movement analysis, particularly when it comes to estimating home range (or ‘Utilization Distributions’, UDs). Unfortunately, the few solutions that have attempted to account for barriers are often incredibly complicated without providing much improvement overall, so previous studies have been forced to simply ‘clip out’ the parts of the estimate that extend over these inconceivable areas (i.e. Heupel et al. 2004; Hammerschlag et al. 2012; Jewell et al. 2012).
