Darwin’s bark spider (Caerostris darwini) is an orb-weaver spider that produces one of the largest known orb webs, web size ranged from 900–28,000 cm2, with anchor lines spanning up to 25 metres (82 ft). The spider was discovered in Madagascar in the Andasibe-Mantadia National Park in 2009. The species was named in honour of the naturalist Charles Darwin, with the description being prepared precisely 150 years after the publication of The Origin of Species, on 24 November 2009.

Its silk is the toughest biological material ever studied, over ten times tougher than a similarly-sized piece of Kevlar. The average toughness of the fibres is 350 MJ/m3, and some are up to 520 MJ/m3, making the silk twice as tough as any other spider silk known. The web of Darwin’s bark spider is remarkable in that it is not only the longest spanning web ever observed, but is among the largest orb webs ever seen, at an area of up to 2.8 square metres (30 sq ft). Nephila komaci, discovered in 2009, and some other Nephila species also make webs that can exceed 1 m (3 ft 3 in) across.

According to professor Ingi Agnarsson, director of the Museum of Zoology at the University of Puerto Rico, the spider’s web occupies a unique biological niche: "They build their web with the orb suspended directly above a river or the water body of a lake, a habitat that no other spider can use". This position allows the spiders to catch prey flying over the water, with webs observed containing up to 32 mayflies at a time. The strong silk and large web are thought to have coevolved at the same time, as the spider adapted to the habitat. Scientists are currently researching how the spider is able to weave such a large web over water along with being able to anchor drag lines on either side of a river.

Like other spiders of the genus, Darwin’s bark spider displays extreme sexual dimorphism, with large females (18 cm) and small males (6 cm).
The spider was described along with a previously undescribed species of fly, which appeared to have a kleptoparasitic relationship with it. The flies often feed on the spider’s catches before the spider wraps them. Occasionally, spiders have been observed to chase away the flies when they land on something that the spider is eating.

   In the Russian zoos mum of a chimpanzee has for some reason refused the cub. The employee of a zoo took the kid to itself home to bring up it. But who would know, that the enormous dog of breed a mastiff becomes the present mum for a marmoset.

   At Tokyo’s Tsukiji fish market held the first in this year’s auction, which was set a new record – for bluefin tuna carcass weight of 269 kg buyer laid 736.000 dollars. Holder of such a valuable tuna became the owner of the Tokyo sushi restaurant chain. He expressed the hope that his purchase at least to some extent help to resume buying spree in Japan, experienced in the past year, the hardest natural disasters.

   In Japan it is known as "Kuro Maguro" (black tuna), and sushi connoisseurs call it "black diamond".

Two babies in the mother koala found in a marsupium, who died after,  her car knocked down.

The driver was not taken aback and did not go any further, and took the wounded animal and took him to the veterinarian.

Doctors saved and brought up two young koalas.

Quebec Society for the Protection of Animals (SPA) had to clean up a stray dog that was extremely dirty. The hair of the animal was so long that the dog seemed to double its size.
