Find out which websites have the least men, if more men or women lie while online dating, and if you’re less likely to marry while you online date. Krause breezily exposes why online dating is so frustrating for so many women, from the weight online dating men prefer anorexic , to the age most men prefer ten years younger , to whether relationships that start online break up more often than those that start offline.

50 First Dates: Sharks and Jellyfish and (a Very Intense) Hike, Oh My!

In the freezing waters of the Arctic a toothed leviathan — the Greenland shark – claims an impressive feat. It now holds the record for longest documented lifespan of any vertebrate. Little is known about Greenland sharks, and even shark specialists see them as creatures of mystery.

Age and growth of sharks: do vertebral band pairs record age?

Cronulla have been dealt a massive blow on the eve of their clash with Brisbane, with centres Josh Dugan and Jesse Ramien both ruled out with hamstring injuries. The pair both failed to prove their fitness in the final captain’s run on Thursday, leaving the Sharks without their key men on both edges. Jackson Ferris will now debut in one of the vacant centre positions, with Siosifa Talakai coming in on the other. It comes after the Sharks already lost Chad Townsend for a month with a calf strain, adding to their challenges in attack.

In a historic scientific find last century, scientists discovered several entire shark skeleton imprints dating back to the mid-Devonian Era, persevered in the.

Whale sharks Rhincodon typus are the largest living fish in the world, averaging about 32 feet 10 meters long and weighing tens of thousands of pounds each. Despite their massive profiles and impressive ranges whale sharks inhabit all tropical waters on Earth and are thought to migrate enormous distances during mating season , the animals are endangered and have proven very hard to study in the wild. Scientists still don’t know some very basic facts about whale sharks — for example, how they mate or how long they live.

Now, marine biologists are much closer to answering that second question thanks to an unusual biological clock — radioactive carbon left over from Cold War-era nukes. In a study published today April 6 in the journal Frontiers in Marine Science , researchers dated carbon — a naturally-occurring type of radioactive carbon that was released into the sky en masse during nuclear weapons tests in the s and s — embedded in the vertebrae of two whale sharks who died long ago in fishing nets in Taiwan and Pakistan.

Much like trees, whale shark vertebrae produce growth rings that increase in number throughout the shark’s lifespan; however, until now, scientists had no idea how often those rings actually form, and so have been unable to use them to confirm a given shark’s age. Related: Attempted whale shark mating caught on camera for the first time in history. Enter carbon a type of carbon that occurs naturally all over the world, but became extra-prevalent in the air and ocean after several industrialized nations conducted hundreds of atmospheric nuclear bomb tests last century.

Because carbon decays at a steady rate, the study authors were able to look at the subtle differences in the ratio of carbon to other isotopes, or forms, of carbon in each shark’s vertebral growth rings, and therefore figure out exactly how much time had past between the formation of one ring and the next.

Girl Talk: Beware of sharks in the dating pool

Dating after 30 can be a scary venture. What was once a dating pool full of great fish that were easy to catch, now seems like a vast, empty ocean. When you cast out your line, the only thing biting your bait seems to be sharks or crappies. I often get letters from people who are reentering the dating world and are shocked at what is swimming in the water.

Now, researchers using radiocarbon dating have identified the remains of a whale shark that lived 50 years, the most ever for that species, says.

Sharks on high alert for resurgent Broncos

Despite their notoriety and role as apex predators, the longevity of large pelagic sharks such as the porbeagle Lamna nasus and shortfin mako Isurus oxyrinchus is unknown. Vertebral growth bands provide an accurate indicator of age in young porbeagle, but age validation has never been reported for any large shark species past the age of sexual maturity. Here, we report the first application of bomb radiocarbon as an age validation method for long-lived sharks based on date-specific incorporation of radiocarbon into vertebral growth bands.

Our results indicate that porbeagle vertebrae recorded and preserved a bomb radiocarbon pulse in growth bands formed during the s. Through comparison of radiocarbon assays in young, known-age porbeagle collected in the s with the corresponding growth bands in old porbeagle collected later, we confirm the validity of porbeagle vertebral growth band counts as accurate annual age indicators to an age of at least 26 years.

The dogfish sharks’ habitat is wide ranging, with species found in marine estuarine Dating from the Jurassic period (– mya) the ground sharks are.

Lumpish, with stunted pectoral fins that they use for ponderously slow swimming in cold and dark Arctic waters, they have blunt snouts and gaping mouths that give them an unfortunate, dull-witted appearance. Many live with worm-like parasites that dangle repulsively from their corneas. They belong, appropriately enough, to the family Squalidae , and appear as willing to gorge on fresh halibut as on rotting polar-bear carcasses.

Once widely hunted for their liver oil, today they are considered bycatch. For some fishermen, a biologist recently told me, netting a Greenland shark is about as welcome as stepping in dog poop. And yet the species has an undeniable magnetism. Its life history is a black box, one that researchers have spent decades trying in vain to peer inside. Where do Greenland sharks mate? What is their global range and population structure?

And, most enticing of all, how long do they live? Verifying this, however, proved nearly impossible. To determine age in other sharks, biologists count the growth rings on their fin spines and vertebrae. But Greenland sharks have no hard tissues in their bodies; even their vertebrae are soft. The longevity question seemed unanswerable.

Greenland shark , Somniosus microcephalus , member of the sleeper shark family Somniosidae order Squaliformes, which also includes the dogfish family, Squalidae that is the longest-living vertebrate known. The species is primarily found in the cold-water environments of the Arctic Ocean and North Atlantic, from Baffin Bay eastward to the Barents Sea , but its range also extends southward to the North Sea and the waters adjacent to the Eastern Seaboard of the United States.

Bulky, with a rounded snout, small fins relative to body size, and gray to brown coloration, Greenland sharks are similar to spiny dogfish Squalus acanthias , except that they lack a spine in front of the second dorsal fin and usually the one on the first dorsal fin. The Greenland shark is one of the largest cartilaginous fishes.

Porbeagle (Lamna nasus) and shortfin mako (Isurus oxyrinchus) sharks have been reported to grow at very differ- ent rates and achieve very different longevities .

Watch the trailer. Title: The One with the Sharks 17 Oct By commending her slick flirting, Ross accidentally makes Phoebe realize that she’s never had a serious long-term relationship, so she breaks down in tears and gets obsessive about her present date, Mike Hannigan. Ross talks to Mike, inadvertently making him wary. For once, Joey is picked up by a girl, Hayley, who thinks he’s inexperienced at dating, but at her oddly familiar apartment he feels sure he’s dated her already.

Joey is shocked she could have forgotten about ‘always memorable’ sex with him, until he notices her roommate Poppy. Monica flies to Tulsa to surprise Chandler, but outside his hotel room hears him excited, apparently about sharks. Dating expert Rachel assures her that men have have the weirdest turn-ons, so she treats her man to a shark nature documentary. Written by KGF Vissers. It is odd that an episode based on Chandler’s supposed arousal of sharks is not better than what it is and it mostly comes down to the underwhelming screenplay here.

Aside from the final dialogue exchange between Chandler and Monica lines like “Let me be a part of this” that capture the absurdity of the premise , this is a really nothing story. Joey’s story with the girl is serviceable without really offering any sort of comedic or dramatic peak. The problem with his character at this point in the show is that he is neither particularly funny bar certain rare exceptions nor a dramatically interesting character and so this storyline, as harmless and tolerable a viewing as it is, does not excel.
