Greenland sharks may live to the age of 400 years: Research

Greenland sharks may live to the age of 400 years: researchers say

The Greenland shark, also known as Somniosus microcephalus, is the longest-living vertebrate on Earth as this huge marine creature can probably live for as many as 400 years, according to a new research published in the journal Science.

A group of marine biologists at Indiana University South Bend estimated that the Greenland shark could have a lifespan ranging from 272 years to nearly 400 years.

UK’s Chester Zoo Becomes the First World's Montserrat Tarantula Nursery

A hundred years have passed since the first time Montserrat tarantula (Cyrtopholis femoralis) was observed in the Caribbean island bearing the same name. A male specimen was collected then and it gave us all the information we have had so far regarding behavior or the breeding pattern of these tarantulas.

Spending life in cold northern waters could be reason behind Greenland sharks’ unusual longevity

Spending life in cold northern waters could be reason behind Greenland sharks’ unusual longevity

A journal Science-published research paper has unveiled that Greenland sharks can live longer than any other known animal with a backbone. Greenland sharks grow very slowly, less than a centimeter per year therefore they are considered to be quite ancient.

Julius Nielsen, at the University of Copenhagen in Denmark, said that they were having an idea that sharks might be quite old. But without a doubt it was a big surprise for them to know that it was the oldest vertebrate animal.

Channel Island foxes’ remarkable recovery could serve as model for partnership-driven conservation efforts

Channel Island foxes’ remarkable recovery could serve as model for partnership-driven conservation efforts

Wildlife conservation requires lot of effort, funding and political will as tough decisions have to be taken. Situation of the Channel Island foxes off the California coast that look no less than a plush toy was so grim 12 years back that no one would have ever thought that they would make a record-breaking recovery.

These foxes have been living on the islands for many thousands of years. But their population started to decline in the 19th century and reduced to such an extent that they were enlisted in the federally endangered species list.

Beekeeping as hobby on rise, but novices may be risking their hives with their decisions

Beekeeping as hobby on rise, but novices may be risking their hives with their decisions

When it comes to backyard beekeeping, you can read books, watch YouTube videos, but nothing would be as beneficial as to have hands-on experience. When you go through different situations involved in backyard beekeeping then only you realize that it is fascinating yet complicated task.

Experts have acknowledged and even welcomed the increasing national interest in beekeeping as a hobby. They also have a suggestion to make that people new to this hobby could put their hives in danger if they do not a check on bee mite population.

Chester Zoo reports Montserrat tarantula hatching in captivity

Chester Zoo reports Montserrat tarantula hatching in captivity

Chester Zoo in Cheshire has announced that a group of around 200 Montserrat tarantulas have successfully hatched at the place. With this, the zoo has become the first place in the world where the hatching has taken place in captivity.

These tarantulas belong to the Caribbean island of Montserrat, but not much is known about them. In 2013, a zoo keeper, who had seen these hairy brown spiders in the wild during his field trips, introduced a dozen of them in the Chester Zoo.

Greenland shark could have lived for up to 400 years: Research

Greenland shark could have lived for up to 400 years: Research

A new study has termed Greenland shark to be the longest-lived vertebrate by at least a century. Scientists said that Greenland sharks have a natural growth rate of less than half an inch per year.

The species is found in the ice-cold waters of the Arctic and North Atlantic and they prefer to prey on smaller fish, but do not mind feasting on anything that slides off the ice, including reindeer and polar beers.

Aggressive recovery efforts revive population of California Island fox

Aggressive recovery efforts revive population of California Island fox

US wildlife officials have announced that California Island Fox is no more endangered. Three out of four sub-species have been removed from the endangered list and the fourth one has been upgraded from endangered to threatened list.

Such a massive improvement is the result of great recovery efforts. Otherwise, 12 years back, the conditions were not in the favor of the Island foxes, a species around the size of a cat living in a group of islands off the Southern California coast.

Recovery efforts made to recover the California Island fox have driven results as the US wildlife officials have removed three subspecies on San Miguel, Santa Rosa and Santa Cruz islands from the endangered list.

Situation was very grim 12 years back when the California Island fox, around the size of a cat was lives in a group of islands off the Southern California coast, was facing survival threats. Factors like non-native predators and pesticides took a toll on their population owing to which the species was enlisted in the endangered list.

Female Greenland shark found to be around 400 years old

Female Greenland shark found to be around 400 years old

Using radiocarbon dating, researchers have come to know that Greenland sharks are now longest-living vertebrates known on earth. Age of 28 animals was determined through this technology and a female was found to be around 400 years old.

The research paper published in the journal Science said that these sharks grow at just 1 cm a year and reach sexual maturity at around the age of 150 years. Study’s lead researcher Julius Nielsen, a marine biologist from the University of Copenhagen said that they were very surprised to know that the sharks were that much old.
