Welcome to Animal | Vegetable | Mineral

I never cease to be awed by the splendor of the natural world, by the forces that shape the earth, and by the diversity and ingenuity of the life that populates it.

Animal | Vegetable | Mineral is a group where those who share this fascination can discuss the Earth and animal sciences of geology, volcanology, seismology, ecology, ethology, primatology, entymology—basically all the –ologies of the natural world.

This Shark Could Be Oldest Living Vertebrate At 512 

Danish scientists believe they've discovered the oldest living vertebrate: A Greenland shark lurking in the frigid North Atlantic and Arctic waters that could be 512 years old, according to the journal Science.
Greenland sharks grow at torpid pace of only about one centimeter per year. So when the scientists discovered a female shark measuring about 18 feet, it was clear the shark had witnessed a few centuries of history.

Little is known about the species. The sharks are known to prowl the Arctic and North Atlantic seas from Eastern Canada to Western Russia, but in 2013, a deep-sea research submarine spotted a 12-foot Greenland shark in the Gulf of Mexico. They have a short and rounded snout and small eyes, and their rough textured skin can be colored creamy-gray or blackish-brown. They are an apex predator with a diet consisting mostly of other fish.
Greenland sharks are known to be relatively abundant throughout the North Atlantic and Arctic, particularly from eastern Canada to western Russia. They occasionally are spotted by deep-sea robotic submarines at latitudes further south, such as in the Gulf of Mexico. They have been observed in depths down to 1.4 miles.

Handy skills

This octopus is more intelligent than all of us. Why? Because when a shark wanted to eat it, it HID FROM IT IN PLAIN SIGHT.
While humans would probably splash about in a mad panic, this eight-legged creature stayed perfectly still under shells it collected, then just swam off.

With the magniificant Woolly Mammoths thawed also comes more oppertunity to gather tusks  for illegal ivory trading (sarcasm, but not really) and explore the Arctic for more carbon.

Methane release from melting permafrost could trigger dangerous glo...ng

Wow, that's impressive! The size of the tusks compared to the men, is incredible!

Comment by Doone on December 3, 2017 at 7:28pm

he beautifully preserved head of the Yukagir woolly mammoth ‒ the most complete ever found. It is 22,500 years old. Discovered in Yakutia in 2002, as well as its head and tusks, the front legs and parts of its stomach and intestinal tract were recovered from the permafrost.

Evolutions speeds up in small island chains beyond the Galapagos.

Finding the Speed of Evolution in a Study of Bird Beaks.

When the ancestors of Darwin’s finches arrived on the Galápagos two million years ago, they gained access to a world of new morsels, untapped by other animals. In a relatively short period, 14 species of finches evolved, specializing in different diets through different beak shapes: short for crushing seeds, sharp for catching insects, long for probing cactus flowers and so on.

This rapid diversification in the presence of new opportunity is called adaptive radiation. Studies of small island bird and lizard populations describe a fast burst of evolution, followed by a slowdown. But broader research has failed to find this fast-then-slow pattern of evolution on a global scale.

An international team of researchers set out to investigate this seeming paradox through a particular trait: the shapes of birds’ bills. Analyzing more than 2,000 species of birds, the researchers suggest in a report published Wednesday in Nature that even though evolution does not slow down globally, the theory of adaptive radiation holds up.

In the case of birds, it is not that evolution slows over time, but rather it switches from generating major changes in beak shape to producing smaller iterations of the same basic shapes, said Gavin Thomas, a professor of animal and plant sciences at the University of Sheffield in Britain and an author of the paper.
