Spider That Eats Other Spiders Cannibalism in the animal kingdom is usually a function of aggression or desperation. Other animals eat their genus mates in times of stress or hunger — rats are omnivores and will not hesitate to eat each other if regular foods are lacking. In the insect world, fleas will cannibalize each other in lieu of a fresh blood source.

5 Of The Most Obscure Predators On The Planet | Care2 Causes

Tweet by Todd Smith By definition, an Apex predator is any adult animal that has no natural predator within its ecosystem. That includes a long list of razor-clawed carnivores and creepy crawlies.

But which critter is really the deadliest of them all? Here are the 10 that make my short list for the baddest of the bad boys from around the world.

Polar Bear On the Arctic icecap every creature fears the polar bear and with good reason. These mighty nomads are the largest land carnivores on earth a position shared with the Kodiak brown bears of southern Alaska and anything on the ice, and sometimes just below it, is food.

Ursus maritimus is a master of stealth dressed in snow camo. Polar bears have been known to stake out blowholes in the ice for hours, waiting for seals to come up for a gulp of air.

When unsuspecting seals surface, one swipe of the paw is all it takes to put seal tartar on the menu. Over 4 feet at the shoulder. When standing on hind legs, large males can reach more than 10 feet. Two-inch claws, brutish strength, may have the best sense of smell in the entire animal kingdom.

Hearing is at least the equal of humans.

Anything on the ice is fair game. They are excellent swimmers—able to reach swimming speeds of just over 6 miles per hour. By contrast, the average human swimmer can only swim about 2 miles per hour.

Sharks The ocean is literally swimming with deadly candidates, from poisonous puffer fish and lethal jellyfish, to toxic sea snakes.

Yes, Carcharodon carcharias has all the requisites for being at the top of the food chain in his environment. About serrated teeth, skin like 4 sandpaper, deadly sense of smell capable of detecting even tiny amounts of blood in water up to 3 miles away.

Oddities found in the stomachs of sharks over the years have included a box of nails, shoes, chairs, the back half of a horse, bottles of wine and even a torpedo.

Accounts vary widely on death tolls per annum, but numbers range from to 2, deaths every year. And those are only the deaths that are reported. No doubt many more head down to the local river to wash clothes or fetch water and simply disappear. Their Australian cousins, Crocodylus porosus, may actually be even worse culprits.

They are very aggressive and are saltwater cruisers, making them death incarnate on practically every estuary north of Brisbane. Up to 1, pounds Size: Up to 20 feet in length. Tons of teeth, ultra-stealthy, extremely quick at close range. Pea-brained but always looking for an easy meal.

Can eat up to half its weight at a single feeding. Interestingly, though, in the natural world, it is the female lioness that does most of the killing. Ultra cunning, keen senses of sight, smell and hearing.

Lethargic on a full stomach, but when the pride goes out for a midnight snack, watch out. Like the velociraptors in Jurrasic Park, lionesses like to hunt in pairs. Ask most African locals what animal they fear most, and old laughing boy is usually right near the top.

Crocuta crocuta is persistent and, like the coyotenever very far from humans or an easy meal. Hyenas like to prey on the aged and infirm. When elderly tribesmen disappear in the bush, these guys are usually responsible for the ax work.

They are also capable of running 40 miles per hour. Ultra cunning, keen senses of sight, smell and hearing Creepy characteristic: Though they generally shy away from man, hyenas are not against adding people to the menu. Hyenas have been reported sneaking into camps and biting the faces off sleeping victims.

Wolves In their eco-system, few can rival the sheer killing power of these amazing predators.The Portia Spider, a Stealthy Predator Essay Spider silk is the number one thing that distinguishes spiders from the rest of the animal kingdom.

Spiders have these special glands that secrete the silk proteins, which are then dissolved in a water-based solution.
