Sharks aren’t the top predator in marine world: videos show

Many people consider sharks as the most ferocious marine creature but a recently captured drone video showed that sharks aren't the top predator in the marine world after all.

During a whale-watching trip in Monterey Bay, photographer Slater Moore caught two adult killer whales feasting on two young sharks on camera. One of the two young sharks was still wriggling as the whales were tearing into their bodies.

Elusive 'ghost shark' filmed alive for first time

Elusive 'ghost shark' filmed alive for first time

The highly-elusive ‘ghost shark’ has been filmed alive for the first time by a team of American geologists. The pointy-nosed blue animal was filed by accident in 2009, but the footage was released recently on the National Geographic channel.

The ghost sharks, which are a relative of sharks and rays, are also known as chimaeras. They are deep-sea animals, and usually live around Australian and New Zealand.

But, American geologists filmed the animal alive prowling at depths of around 2 kilometers off the coast of California and Hawaii.

Lack of right wiring in primates’ brains prevents them from producing human-like speech

Lack of right wiring in primates’ brains prevents them from producing human-like speech

Monkeys have a vocal tract capable of producing human-like speech but they are unable to produce words because they lack the right wiring in their brains, according to a new study.

Researchers have long been intrigued by primates’ failure to talk like humans. On Friday, a group of researchers reported that their study suggested that monkeys have the required vocal tract but they don’t have the right wiring required to produce words.

Giraffes facing silent extinction: IUCN

Giraffes facing silent extinction: IUCN

Giraffes are apparently facing a silent extinction as the global population of the iconic animal has drastically declined in the past three decades, the International Union for the Conservation of Nature (IUCN) warned in its latest report.

According to the newly released IUCN report, the global population of giraffes slipped from around 155,000 in 1985 to fewer than 97,000 in 2015.

New bird study has implications for robots & drones: researchers say

New bird study has implications for robots & drones: researchers say

At the time of lift off, birds’ wings generate tiny, circular currents of air known as wingtip vortices. A new study allowed a group of researchers to visualize and examine these wingtip vortices, and they discovered that found that the actual way the air moves is different from what is commonly thought based on theoretical calculations.

Rare weasel species returns to Mount Rainier National Park

Rare weasel species returns to Mount Rainier National Park

A large crowd gathered at the Mount Rainier National Park in Washington State late last week to herald the return of a rare weasel species that had been missing in the area for the last seven decades.

A total of 10 Pacific fishers, which had been trapped in British Columbia, were set free at Mount Rainier National Park as part of wildlife officials’ efforts to reintroduce the native species to its historical range.

Australia’s Great Barrier Reef suffers its worst coral die-off

Australia’s Great Barrier Reef suffers its worst coral die-off

The Great Barrier Reef in Australia suffered its worst coral die-off this year as warmer seas killed more than two-thirds of a 700-kilometer (435 miles) stretch of coral within the last nine-month period, researchers announced on Monday.

The Australian Research Council’s Centre of Excellence for Coral Reef Studies said in its latest report that the reef’s northern region, off the coast of Queensland, Australia, suffered a loss of 67 per cent of its shallow-water corals during the last eight to nine months.

Coconut crab’s pinching force is equal to bite force of adult lion: research

Coconut crab’s pinching force is equal to bite force of adult lion: research

The pinching force of an adult coconut crab is almost equal to the deadly bite force of an adult lion, according to a study published in the journal PLOS ONE.

The so-called coconut crabs (Birgus latro), which inhabit islands in the Indian and southern Pacific oceans can grow up to 9 pounds in weight, with a leg-span of 3 feet. These large crabs can easily crack open the hard shells of coconuts.

Coconut crabs have the most powerful claws: study

Coconut crabs have the most powerful claws: study

The scary claws of the enormous coconut crab (Birgus latro) can pinch with a force greater than that of any other crustacean, a new study revealed.

Cracking open a coconut without using any tool is quite a difficult job, but a coconut crab that can grow up to a weight of around 9 pounds with a leg-span of 3 feet can easily crack open the fruit.
