In honor of Discovery’s Shark Week, The Beacon will be celebrating the wonders of sharks through Friday. With over 350 shark species, the class Chondrichthyes is full of biodiversity, from sawfish to manta rays and famous great white sharks.
This week, we’re asking our readers to weigh in your favorite shark species. You have until Thursday, August 14 at 11:59 p.m. to pick one of the shark species below (take a look beneath the poll for a glimpse of each species), and whichever shark gets the most votes will be featured on The Beacon on Friday with a full species bio.
From our obsession with shark-themed movies like “Jaws,” to our desire to collect shark teeth at the beach, there's no denying that humans have a fascination with these cartilaginous fish.
But, just how well do you know these creatures? Even if you consider yourself pretty knowledgeable about these species, there’s always something new to learn. Take a look below at ten cool shark facts that may make you look at these ancient creatures in a different light.
Ocean News: Sharks Seized from Poachers in the Gulf of Mexico, Elusive Jellyfish Makes Rare Appearance, and More
- It turns out that sharks may be confusing surfers for birds, according to a study that examined a previous deadly shark attack. That study found that the motions made by kite surfers puts them at particular risk. Discovery News
When you’re out swimming or surfing at the beach, have you ever wondered which ocean animals surrounding you have teeth? It turns out that sharks aren’t the only marine animals with teeth—a tool in some marine animals may be more widespread than you thought.
From hundreds of sharp, razor-blade-like teeth in great white sharks to the singular long, spiraled tooth on narwhales, teeth come in all shapes in sizes in marine ecosystems. This diversity is for good reason—some use their teeth to shred and slice prey, while others use their teeth more as a harpoon.
Many marine species face endless obstacles: Overfishing, pollution, and habitat destruction are large threats, as well as climate change and its associated negative impacts. Factors ranging from their habitat, food source, predator defense, migration routes, and breeding grounds are already changing from warming seas, and these impacts are so widespread that it’s caught fisheries managers’ attention.
Ocean News: Scientists Sound Alarm Over Shark Cull Program, Fabien Cousteau Returns from Underwater Mission, and More
- An international group of 301 scientists submitted a letter to Western Australia's Environmental Protection Authority expressing concern over the controversial shark cull program, saying it could effect the ecology of the oceans. The program caught 172 sharks during its trial period this past spring. The Guardian
Sharks are often portrayed as the monsters of the deep or the villains in horror movies, famous for their menacing teeth and killer attack instincts. In real life, however, sharks have recently inspired scientists to make strides toward improving treatments for Alzheimer’s disease and multiple sclerosis.
Each year, millions of sharks are slaughtered for their fins to meet the demand for shark fin soup. Over the past few years, several U.S. states passed laws against the trade in shark fins to help shut down the market. In the recent issue of Oceana magazine, we reveal how a government agency is taking steps to undermine these bans.
You might not have heard, but sharks are in trouble from an unlikely source—our own federal government. The National Oceanic and Atmospheric Administration, the government agency tasked with managing our nation’s fisheries, is taking steps to undermine state laws that protect sharks.
Because you can’t keep pulling out the same stale old facts at your Shark Week parties, we're going to hook you up with some fresh new shark facts to astound and amaze your friends and family! When we told a few of these shark facts to the basking shark in the photo below, his jaw dropped:
1. The basking shark uses its enormous mouth to filter plankton out of up to 395,000 gallons (1.5 million liters) of seawater through the huge gills that almost encircle its head
2. The curiously named cookiecutter shark is a parasite that bites circular chunks out of its prey. Holding onto its victim by suction, it twists itself around, using its razor-sharp lower teeth to bite out a cookie-shaped piece of flesh. As if that wasn’t freaky enough, the nocturnal cookiecutter shark lures its victims with glowing green bioluminescent lights on its belly.
