The Fluke Shot by LisaSkelton
photos by paul nicklen for national geogrphic, who notes: "i have been traveling to northern baffin island for more than twelve years to try and get one underwater picture of a male narwhal. narwhals are very shy. they have a sensitive nature and excellent echolocation. you can see hundreds passing by the ice edge, but when you slip into the water, you may never see one.
"late one afternoon, i had been in the -1.7°C water for a couple of hours, and i was freezing so badly that my legs and arms were cramping up. i couldn’t feel my lips around my snorkel, so i just stared into the black 2,000-foot abyss trying not to think about how cold i was.
"then, out of the corner of my eye, i noticed something bright traveling through the murky water. i turned my head, and there they were: several male narwhals, swimming in beautiful formation. i put my frozen finger on the shutter and, as i was about to take the picture, the narwhal closest to me let out a stream of bubbles. i snapped the picture in what was the most incredible moment of the assignment." .
Scientists have speculated that the male tusks are either a sensory organ, a device for battling other males or an elaborate reproductive signal. New evidence shows they are the whale version of deer antlers and peacock feathers.
The researchers discovered a positive correlation between the size of male narwhal’s tusks, which are really just long teeth, and the mass of their testicles. The relationship of tusk length with testicle size only applies to mature males, not juveniles. The researchers propose the tusks have a critical role in mating.
Larger males, with proportionately larger tusks, would intimidate smaller males and are more likely to be successful in a contest for mates.
Captive female narwhal have been observed becoming excited by the presence of a tusk-shaped object such as a pole or broom handle in their pool, butting the object, and jockeying for position close to it.
Soooooo, I got my TMNT Revoltechs in today… and this was the first thing that came to mind when posing.
never too old to ‘play’ around with action figures
C’mon Leo don’t look so shocked, that’s what dreams come true are made of <3
SO GOOD I want them aaah D: D:
Omg I wish they weren’t so expensive!! Woah! I have the action figures from the CGI TMNT movie, but they weren’t $60 a piece! I wish the toys in the store weren’t stupid looking. :/
Add dolphins to the list of magnetosensitive animals. Dolphins are indeed sensitive to magnetic stimuli, as they behave differently when swimming near magnetized objects.
Magnetoreception implies the ability to perceive a magnetic field. It is supposed to play an important role in how some land and aquatic species orientate and navigate themselves. Some observations of the migration routes of free-ranging cetaceans, such as whales, dolphins and porpoises, and their stranding sites suggested that they may also be sensitive to geomagnetic fields.
Researchers watched the animals’ spontaneous reaction to a barrel containing a strongly magnetized block or a demagnetized one. Except from this characteristic, the blocks were identical in form and density.
The analyses revealed that the dolphins approached the barrel much faster when it contained a strongly magnetized block than when it contained a similar not magnetized one. However, the dolphins did not interact with both types of barrels differently. They may therefore have been more intrigued than physically drawn to the barrel with the magnetized block.
I’m up way too late. ‘consentacles’ dohohoho
Always be sure to drink and tentacle responsibly.
Omg the bottle of Kraken!! X3
Swimming with Wild Belugas in the Churchill River
how can you capture this? how can you kill this?
The #belugas here at Georgia Aquarium are an admired favorite of our guests, young and old, and inspire the message of #conservation to each person who sees them. But what about their wild counterparts? We encourage you to learn more about the history of our Beluga Conservation Project and our steadfast commitment to conserving and protecting this magnificent species globally in our latest blog post from David Kimmel, Georgia Aquarium President and Chief Operating Officer:http://goo.gl/Ys99lW
I want to squish my forehead to a beluga melon like this!! I want to do it so bad!
