Rare Animals - The Japanese River Otter

japanese-river-otterThe Japanese River Otter, a member of the weasel family, reaches approximately 70 centimeters (28 inches) in length. The creature once widely inhabited midstream and downstream regions along rivers throughout Japan. However, its number has drastically diminished due to excessive pelt hunting.

The last official sighting of the Japanese River Otter was in the southern part of Kochi Prefecture in 1979, and since that time, no sighting of the otter has ever been confirmed. An official search to ensure its survival has recently gone under way. Continue Reading »

Endangered Species - The Golden Eagle

golden-eagleThe Golden Eagle (Aquila chrysaetos) is one of the best known birds of prey in the world. It is about 90 cm in length, has a wingspan of 220 cm and a weight of 5 kilos. Like all eagles, it belongs to the family Accipitridae.

Once the Golden Eagle lived in all temperate Europe, North Asia, North America, North Africa and Japan. In most areas this bird now is a mountain-dweller, but in former centuries it was also distributed in the plains and the forests. Continue Reading »

400-million Year Old Chemical from Dead Crustaceans

cockroach-chemicalChemical from dead insects, crustaceans dates back over 400 million years

A new study of cockroaches and other creatures finds the smell of death goes way back.

Insects and other animals are known to use a range of chemical odors to communicate. The death smell, released by cells of a deceased creature, is thought to serve as a warning of possible disease or that a predator might be nearby, the researchers explain. Continue Reading »

Weird Creatures: Alligator snapping turtle

alligator-snapping-turtleThe prehistoric-looking alligator snapping turtle is the largest freshwater turtle in North America and among the largest in the world. With its spiked shell, beak-like jaws, and thick, scaled tail, this species is often referred to as the “dinosaur of the turtle world.”
Found almost exclusively in the rivers, canals, and lakes of the southeastern United States, alligator snappers can live to be 50 to 100 years old. Males average 26 inches (66 centimeters) in shell length and weigh about 175 pounds (79.4 kilograms), although they have been known to exceed 220 pounds (100 kilograms). The much smaller females top out at around 50 pounds (22.7 kilograms). Continue Reading »

Animals and Their Roles in Indian Mythology

indian-mythology-animalsAncient Indians had recognized the animals’ right to co-exist with man and therefore they were loved, nurtured and even worshipped. In order to impress upon the commoners about their importance, the animals were given the status of gods and goddesses. They declared that Almighty incarnates in different animal forms. The kings and the emperors opted different animals in their emblems. Many festivals were/are observed in honor of several animals. In order to inculcate love for animals among children, animals were made heroes in stories. The rulers gave them prime position in art and architecture. Unfortunately, today we are neither adopting ancient Indians’ compassionate attitude, nor scientific approach of the westerners towards these animals and hence we are heading towards a catastrophe.

Weird Creatures: Betic midwife toad

betic-midwife-toadThe Betic midwife toad is found in a number of isolated and fragmented populations around the mountains of southeastern Spain, occurring at altitudes of up to 2,140 metres above sea level. Females lay a string of eggs that the male wraps around his hind legs, carries until they are ready to hatch, and finally deposits in a pool of water where the tadpoles remain for up to a year. It is threatened by loss of suitable breeding habitat through excessive water withdrawal, droughts and the modernisation of agricultural practices leading to the abandonment of cattle troughs, which used to provide good breeding habitat.

Weird Creatures: Chinese Giant salamander (Andrias davidianus)

andrias-davidianusThe Chinese giant salamander is the largest salamander in the world, and is fully aquatic, with many adaptations for this lifestyle. It grows up to 1.8 metres in length, though most individuals found today are considerably smaller.
The skin is dark brown, black or greenish in colour and irregularly blotched. It is also rough, wrinkled and porous which facilitates respiration through the skin as this large amphibian lacks gills. Continue Reading »

They also have thin legs, with long fingers and webbed toes. They have horizontal pupils in their eyes and they are mainly nocturnal. Continue Reading »

Earliest Animal Life Leaves Steroid Marks

animals-steroid-marksMolecular fossils push back earliest appearance of animal life
Gordon D. Love started out hunting for oil and ended up striking paleobiology gold. Together with an international team of scientists, he has unearthed chemical calling cards that constitute the oldest fossil evidence for animals.
The earliest animals were soft-bodied creatures such as marine sponges, which don’t leave skeletons for researchers to find. However, a class of modern sponges with ancient ancestors contains a distinct chemical signature, a series of 30-carbon biomarkers that arise when steroids in sponge cell membranes break down over time. Love, a geoscientist at the University of California, Riverside, found those hardy biomarkers, which are called 24-isopropylcholestanes, in rock that dates back 635 million years, trumping the next oldest evidence for animal life by tens of millions of years (Nature 2009, 457, 718).

Weird Creatures: Ghost frogs

ghost-frogWith colors and patterns that almost perfectly match the forest floor where they live, the ghost frogs live up to their name and, when they are very still, seem to vanish into the background. The Cape ghost frog, also known as Purcell’s ghost frog, has a brown back and head that are covered with black blotches—almost as if someone had shaken out a wet paintbrush and splattered black paint on the frog. When in its habitat where the green mosses and plants and dark clumps of dirt and pebbles form a patterned blanket on the ground, the frog blends in well enough almost to disappear. People and predators can walk within a few feet of this frog and never notice it. Continue Reading »
