Fish-scale gecko escapes predators’ grip by shedding scales and skin

Researchers have discovered a new type of gecko, an evasive little lizard that can escape predators’ grip by shedding its scales as well as skin.

The new species, dubbed Geckolepis megalepis, has the biggest scales of any fish-scale gecko, some of which measure nearly 8 per cent of its total body length. A team of researchers, led by Mark D. Scherz of Ludwig Maximilian University of Munich, discovered it northern Madagascar’s limestone karst.

Viscoelastic Tongue Helps Frogs to Catch Prey Easily: Research

Viscoelastic Tongue Helps Frogs to Catch Prey Easily: Research

Frogs use a viscoelastic tongue and non-Newtonian saliva to catch prey, as per a new research paper from researchers at Georgia Institute of Technology has informed. The research paper has been published in Journal of The Royal Society Interface. Frogs use their whip-like tongue and it hits the prey with a strong force. The tongue is very soft and a unique reversible saliva offers the stickiness to this action, which helps frogs to trap their prey. The swift action and stickiness doesn’t give a chance to the prey to escape. Before the prey knows it, it is already in mouth of the frog.

Frogs use sticky spit to catch prey

Frogs turn to sticky spit to catch prey

Frog’s sticky spit is one of the catchiest spits on the planet, and it is tailor-made to grab bugs, according to a new research on frog saliva.

Led by Alexis Noel, a PhD student at the Georgia Institute of Technology, a team of researchers used high-speed photography as well as an instrument known as Rheometer to analyze saliva collected form 15 frogs under prey-capturing conditions.

Explaining how he collected frog saliva, Noel said he got fifteen frogs, and scraped their tongues for hours. He called it a “pretty disgusting” experience.

Scientists solve Killer Whales menopause mystery

Scientists solve killer whales’ menopause mystery

Benefits of grandmothering may have played a major role in the success of older female orcas (killer whales) but the costs of being outcompeted by their daughters apparently play a role in the emergence of their menopause, a new study suggested.

According to the study, published in the journal Current Biology, younger females are more likely to mate and reproduce than their older counterparts. They found that this trend puts off mother orcas from reproduction, which in turn make them more focused on raising their younger members of their families instead.

Among mammals, only humans, killer whales and short-finned pilot whales experience menopause.

Biologists discover ruby sea dragon in the wild

Marine biologists had been of the view that only two types of sea dragons existed, the leafy and weedy, until they discovered a third type in 2015. The third type of the enchanting fish, the ruby sea dragon, was first found among museum specimens; and now biologists have spotted a ruby sea dragon swimming in the wild too.

Spotted for the first time in the wild, the ruby sea dragon has deep red color and appears like a stretched-out sea horse and hump like a camel. It can curl its tail.

Endangered vaquita porpoise conservation efforts will receive help from US Navy trained Dolphins

The U.S. Navy trained dolphins will help in efforts to save endangered vaquita porpoise. As per the latest data available, there are nearly three dozen endangered vaquita porpoise and the species faces high risk of extinction. Many international organizations have also been helping Mexican authorities in saving endangered vaquita porpoise. The U.S. Navy trained dolphins will be deployed in the Gulf of California. The U.S. Navy has been training dolphins and sea lions since 1960s in sniffing out mines and in navigation when lose in the open sea.
