Strange Animals - The Kiwi Bird

kiwi-strange-birdThe Kiwi bird, of the order Apterygiformes-Ratitae, occurs only in New Zealand. Although primarily a bird of New Zealand’s native forests, kiwis also live in scrub and native grasslands. Because the kiwi is a semi-nocturnal, secretive bird, few New Zealanders have seen their national bird in the wild.
The kiwi is the sole survivor of an ancient order of birds including the now extinct moas. A flightless bird about the size of a domestic fowl, the kiwi has coarse, bristly, hair-like feathers. Females are larger than males.
Kiwis grow to about the size of a chicken and weigh between three and nine pounds. They have no tail and tiny two inch wings which for all practical purposes, are useless. Despite its awkward appearance, a kiwi can actually outrun a human and have managed to survive because of their alertness and their sharp, three-toed feet, which enable them to kick and slash an enemy.

Strange Animals - Bumblebee Bats

bumblebee-batBumblebee Bats are the world’s smallest bat, in fact they are the world’s smallest mammal. They are between 29 and 33 mm (1.1 - 1.3 inches) in length, they have no tail, they have a wingspan of approximately 170 mm (6.7 inches) and they weigh 2 g (0.07 oz).
They have reddish/brown or grey upper parts with their underside being pale in colour. They have dark coloured relatively wide wings with long tips that enables them to hover.
Their nose is pig-like, they have small eyes and relatively large ears. They have a large web of skin between their hind legs, known as the uropatagium, that gives them assistance when in flight.
They are most active at dusk when they fly around teak trees and clumps of bamboo capturing insects.

Strange Animals - Olm

olm-strange-animalThe olm (Proteus anguinus) is a species of blind amphibians endemic to the the deep underground caves of the Dinaric karst of southeastern Europe. The unusual appearance of the olm is the result of extensive adaptations to its habitat. Olms inhabit deep underground lakes and pools, where they spend their entire lives in almost complete darkness. As a result, the skin of these animals is devoid of pigment, making it resemble human flesh. The local name of the creature is “Čovečja Ribica,” which means “Human Fish”.
The snake-like olm was mentioned by Charles Darwin in his seminal work On the Origin of Species as an example of the reduction of structure through disuse. The eyes of the olm are severely underdeveloped, an adaptation to its dark surrounding. Larval olms retain normal eyes for the first four months of life before the organs start to regress. By the time the species reaches its adult stage, the visual system has almost completely atrophied.

Strange Animals - Lesbian Leapin’ Lizards

leapin-lizardsReaders of science journals know a good deal about bisexual aphids, “homosexual” gulls, and “transvestite” fish, species in which the male adopts the coloration and movements of the female to trick other males. Some researchers argue that every expression of human sexuality has some sort of analogue in the animal world. But even jaded followers of animal sex studies will have to admit that a Harvard team has now discovered something really new: “lesbian” lizards that copulate like males.
So far biologists have identified 27 kinds of parthenogenetic lizards—all-female species that lay eggs to produce exact genetic copies of the mother. On field trips in Arizona and Colorado, a team of researchers headed by Psychobiologist David Crews found that four of these species engage in mock male-female sex.

Strange Animals - Angler Fish

anglerfish-weird-fishAn anglerfish is a fish in the order Lophiiformes. This order encompasses a wide range of fish in an assortment of families, but all of them share some very distinctive traits which have made them quite famous. Unfortunately for the anglerfish, one of these traits is extreme ugliness; anglerfish are among the most bizarre looking organisms in the sea which can be seen by the naked eye, and an encounter with one is not easily forgotten.
The common name “anglerfish” comes from a unique biological adaptation exhibited by members of this order. Anglerfish have developed extremely long dorsal fins, with the part of the fin near the head being entirely separated. The section of the fin dangles in front of the face of the anglerfish, sort of like a long fishing rod. To complete the image, the fin terminates in a fleshy bulb of “bait” which is meant to intrigue other fish. In deep sea dwelling anglerfish, the bait exhibits bioluminescence, essentially creating a neon sign to attract prey.

Strange Animals - Solenodon

solenodon-strange-animalsAt first glance the Solenodon is an unremarkable fellow. He looks like a big Shrew, with an enormous head, a great big nose, a bit of a clumsy demeanour, all in all a bit of a shambles… consequently he is often stopped by Japanese tourists in the mistaken belief that he is British Royalty. Asides from his rather unfortunate manner he really is the most magnificent beast. You see it is his downright dimness that sets him apart from the other Mammals, perhaps not that unrelenting dunce the Slow Loris, but we’ll get to him too.
The Solenodon is one of the rarest creatures on the planet. At one point many different species of Solenodon roamed across North America, now there are only two species left; the Haitian paradoxus and the Cuban cubanus. They really are incredibly scarce as they have been decimated by the arrival of man, and more significantly cats, dogs and the introduced mongoose.

Competition for the Strongest Animal on the Planet

archegozetes-longisetosusThe term “strongest animal” can be misleading, but most often it refers to how much an animal can lift relative to its own weight. Let’s see the world’s strongest animals in terms of different standards :
Until recently (2007), it was thought that the Rhinoceros beetle was the world’s strongest animal by this standard, capable of lifting 850 times its own weight. This is comparable to a 68 kg human lifting a 67 ton . Some of the largest Rhinoceros beetles weigh 120 grams, making them capable of carrying about 100 kg (220 lb). This means that a strong Rhinoceros beetle would be capable of carrying a heavy man.

The Oldest Animals on the Planet

clam-oldest-animalJonathan the tortoise and Mischief the cat may have hit the headlines for their longevity, but there are plenty of other creatures giving them a run for their money in the age stakes.
Rabbit: Fourteen-year-old George, from Tewksbury, Massachusetts in the US, was recognised as the oldest rabbit in the world by the Guinness Book of World Records earlier this year.
The average life expectancy of a rabbit is six to eight years, making George an estimated 160 years old in human terms. His owners met at college and fed their pet Doritos.

Primitive Shark was Filmed in Japan

primitive-shark-japanThe Awashima Marine Park in Shizuoka, south of Tokyo, was alerted by a fisherman at a nearby port on Sunday that he had spotted an odd-looking eel-like creature with a mouthful of needle-sharp teeth.
Marine park staff caught the 1.6 metre (5 ft) long creature, which they identified as a female frilled shark, sometimes referred to as a “living fossil” because it is a primitive species that has changed little since prehistoric times.
The shark appeared to be in poor condition when park staff moved it to a seawater pool where they filmed it swimming and opening its jaws.
