The Long-eared JERBOA



The Long-eared Jerboa, Euchoreutes naso, is a nocturnal mouse-like rodent with a long tail, long hind legs for jumping, and exceptionally large ears. It is distinct enough that authorities consider it to be the only member of both its genus, Euchoreutes, and subfamily, Euchoreutinae.

It has been reported in China and in ten localities in desert habitats of Trans Altai Govi Desert and the Gobi Desert in Mongolia.

A large part of the species is believed to occur in Mongolia within protected areas.

Very little is known about the species.

Globally, it is listed by IUCN as Endangered and within Mongolia it is listed as Vulnerable.

The cause of their threatened status is not well understood, but it has been suggested that it is due to habitat disturbance from mining activities, overgrazing and agriculture as well as possibly climate change.

The SHOEBILL aka the Whalehead

The Shoebill, Balaeniceps rex, also known as Whalehead, is a very large stork-like bird. It derives its name from its massive shoe-shaped bill.

The Shoebill is a very large bird. The adult is 115-150 cm (45-60 in) tall, 100-140 cm (40-55 in) long, 230-260 cm (91-125 in) across the wings and weighs 4 to 7 kg (8.8-15.5 lbs).The adult is mainly grey while the juveniles are browner. It lives in tropical east Africa in large swamps from Sudan to Zambia.

This species was only classified in the 19th century when some skins were brought to Europe. It was not until years later that live specimens reached the scientific community. However, the bird was known to both ancient Egyptians and Arabs. There are Egyptian images depicting the Shoebill, while the Arabs referred to the bird as abu markub, which means one with a shoe, a reference to the bird's distinctive bill.

The TONGUE EATING LOUSE

The Cymothoa exigua or the Tongue eating louse is a parasitic crustacean of the family Cymothoidae(Isopods). It tends to be 3 to 4 cm long. This parasite enters through the gills, and then attaches itself at the base of the spotted rose snapper's (Lutjanus guttatus) tongue.

It then proceeds to extract blood through the claws on its front three pairs of legs. As the parasite grows, less and less blood reaches the tongue, and eventually the organ wastes away from lack of blood. The parasite then replaces the fish's tongue by attaching its own body to the muscles of the tongue stub. The fish is able to use the parasite just like a normal tongue. It appears that the parasite does not cause any other damage to the host fish. Once C. exigua replaces the tongue, some feed on the host's blood and many others feed on fish mucus.

They do not eat scraps of the fish's food. This is the only known case of a parasite functionally replacing a host organ.

There are many species of Cymothoa, but only C. exigua is known to consume and replace its host's tongue.

In 2005, a fish parasitised by what could be Cymothoa exigua was discovered in the United Kingdom. As the parasite is normally found off the coast of California, this led to speculation that the parasite's range may be expanding. However, it is also possible that the isopod traveled from the Gulf of California in the snapper's mouth, and its appearance in the UK is an isolated incident. The animal in question will be put on display in the Horniman Museum.

Giant SNAKES

Ancestor of the giant snakes
The biggest snake yet discovered, Titanoboa cerrejones, slithers alongside one of its presumed prey, a primitive crocodile, 60 million years ago in an artist's conception.

At least 42 feet long (13 meters) and weighing 2,500 pounds (1,135 kilograms), the snake was "longer than a city bus ... and heavier than a car," said University of Toronto Mississauga biologist Jason Head, who announced the find.

4 June 2009 a Lisburn man Mike Warner (73) and his son Greg (44) have done, seeking evidence that this was the home of the Yacumama and actually capturing a picture of the creature. A leviathan of the jungle, which reports say reaches 40 metres in length and two metres in diameter, it dwarfs any snake known to science.

This anaconda is not green but dark brown and is known by the locals as the 'black boa' or 'Yacumama'.

"Yacumama is translated as Mother of the Water and reports of this giant snake abound throughout the Amazon basin and history."

After an exhausting 12 days in the jungle and a 30 hour trip back home the father and son team were finally able to examine their photo evidence in more detail, over 700 photos and five hours of video.
"The data is immense and will take months to fully appreciate but already it supports our theories of 'channels' created by these giants as they make their way through the dense jungle knocking down trees 90 feet tall, but more importantly we managed to catch one of these reclusive giants on camera as it made its way through one of its watery channels."

ALBINO Animals

Albinism (from Latin albus, "white" also called achromia, achromasia, or achromatosis) is a form of hypopigmentary congenital disorder, characterized by a partial or total lack of melanin pigment in the eyes, skin and hair, or more rarely in the eyes alone. Albinism results from inheritance of recessive alleles. The condition is known to affect mammals (including humans), fish, birds, reptiles and amphibians. While the most common term for an organism affected by albinism is "albino" (noun and adjective), the word is sometimes used in derogatory ways towards people; more neutral terms are "albinistic" (adjective) and "person with albinism" (noun). Additional clinical adjectives sometimes used to refer to animals are "albinoid" and "albinic".

It is not the same as leucism, where all integumental pigment is absent at least in patches but the eyes have their usual color.Leucistic animals are often mistaken as being albino creatures, such as white lions. Leucism is a condition similar to albinism, characterized by reduced pigmentation in general and can also affect distribution of pigment on the hair shaft, but unlike albinism, it’s caused by a reduction in all types of skin pigment, not just melanin. Chinchilla and other mutations can also cause white animals, such as some of the animals depicted here, including white peacocks, and white tigers, which are typically white rather than albino.
