Polar bear vs grizzly.


Overall, I think that the animals themselves are fascinating enough to have to resort to fighting among themselves to attract attention.



But when I saw the video I was surprised. The polar bear is an apex predator and is billed as the largest land predator. They can weigh 1550 lb and measure 8,5 fts long. With these measures, I always thought that the polar bear could make any other predator on. But ... apparently yes. His cousin the grizzly famosisísimo. The latter is shorter (8,2 fts) and weighs slightly less (up to 1450 lb) than the polar bear. Although the Grizzly is more fierce, strong and brave. Otherwise, watch the video.

Dumbo Octopus

They are in the depths of the ocean where we find this so strange and funny animalete. This is an octopus (really a kind of octopus) who lives between 3,000 and 5,000 meters deep and is called the Dumbo Octopus (Grimpoteuthis) because their fins resemble the ears of an elephant.

Where this little cephalopod lives of 20 cm long, is less sunlight and that explains why it is white or very light shades.

Living in the abyssal zone, we know very little about the Dumbo Octopus, except to eat down to the depths. And the way you eat, a unique feature of this octopus. Compared with others, Dumbo swallows its prey whole and not going pecking as do other octopuses. Among their prey can find some small crustaceans and marine worms.

You can flush the transparent layer of their skin at will. The Dumbo octopus largest ever recorded was 1.8 meters long and weighed about 6 kg but as we said, the normal size for different species is believed to be smaller.
