In last December, Portuguese scientists learned that fishermen and boaters noticed a dead sunfish in the central North Atlantic. When researchers saw the carcass near Faial Island in the Azores, they nearly couldn’t believe it.

Scientists say the bump-head sunfish (Mola alexandrini) is the biggest bony fish ever found. The fish weighed 6,050 pounds, 882 pounds more than the previous record-holder, a 5,070 pound sunfish off the coast of Japan in 1996.

A new publication in the Journal of Fish Biology provides more facts about the enormous sunfish found in the Azores last year.

The oldest human fossils ever discovered on the European continent are 1.4-million-year-old facial bones, which could change the course of human prehistory, according to the researchers involved in the historic discovery.

Speaking to Anadolu Agency, Aurora Martin, the archaeologist and general coordinator of the Museum of Human Evolution in Burgos, said: “We do not yet know to which first human species the fragments found belonged”.

The bones, found at the end of June at the caves of the Sierra de Atapuerca excavation site near Burgos, constitute “a breakthrough that will help rewrite the history of human evolution,” she added.

Amazing Planet: Elephants can hear with their feet and understand different languages

Elephants can pick up low frequency vibrations with their feet

Elephants are skilled communicators with memories that could give humans a run for their money. But culling and habitat loss is making it harder for them to pass on this expertise.

They’re known as gentle giants. Elephants, found across Africa and Asia, are the largest mammals on land. And their massive bodies — from their sensitive feet to their complicated brains — are perfectly attuned to these regions’ savannas and forests.

Tigers in the Sundarbans are in imminent danger of being hungry due to the rising spotted deer poaching.

The big cats, well-known as the Royal Bengal Tiger in the southern mangrove forest of the country hunt spotted deer, monkey, and wild boar.

According to a review study by the Implementation, Monitoring and Evaluation Department on the Bengal Tiger Conservation Activity project, spotted deer is the staple diet of the tiger.

No country for elephants

Mostafa Yousuf
As if it wasn’t hard enough for elephants to survive in this country, in a tragic development, it was discovered that they are not just dying by electrocution. Shooting down the animals straight up has become seemingly rampant to protect encroached forest lands.
In Cox’s Bazar, 18 elephants were shot down in the span of three years, from 2019 to 2021. The Daily Star found this grim picture after piecing together the three years’ data. During this time, nine elephants were

Snakes help monitor Fukushima Fallout

Researchers have equipped snakes with tracking devices and dosimeters to measure the radiation levels in the vicinity of the Fukushima Dai-ichi nuclear power plant in Japan, in which there were three core meltdowns in March 2011 – one of the largest anthropogenic releases of radioactive contamination in history.
Radiation leaks forced tens of thousands of people to flee the area. Many have returned in the 10 years since but

Paleontologist from Senckenberg Research Institute, Weimar, Germany, recently unearthed the remains of a cheetah which might just have been the bloodiest killers of the ancient times wandering at one of the oldest known habitat of human beings. It is well known that the only remaining species of cheetah, Acinonyx jubatus, is the fasted animal on Earth with the capability of running up to 70 mile-per-hour. But the

Unique pig-nosed turtle is over-harvested in New Guinea

Numbers of pig-nosed turtles have declined steeply over the past 30 years, researchers have discovered.
The unique reptile has become an international conservation icon, due to it having no close relatives and being considered the turtle most adapted to life underwater in freshwater ponds and rivers.
Yet demand for its eggs and meat in Papua New Guinea, one of the turtle’s main

‘Ants can identify their worst enemy’

A study of the ant species Temnothorax longispinosus has revealed that it can spot its worst enemy and react with appropriate aggression.
The ant colonies are often invaded by slavemaker ants, which steal their pupae. So when the ants spot a slavemaker, they attempt to kill it by biting and stinging.
But the insects do not waste their energy on less threatening intruders

Birds eavesdrop on predator chipmunks

Ground-nesting birds eavesdrop on chipmunks in order to protect their nests, according to scientists.
Ovenbirds and veeries live alongside egg-eating chipmunks in the Hudson Valley, New York, US.
Researchers have found that when simulated chipmunk calls are played, the birds nest up to 20 metres further away.
The study is the first to show that birds heed the chatter of non-avian species

Wildlife in jeopardy

Hunger, death on offer as forests vanish fast
The number of phone calls we receive every day is amazing. People call to say fishing cats have been killed or captured. Jungle cat kittens found. Vultures lying sick. And of course, tigers have been killed.
If we put together all these pieces of information, we get a terrifying bigger picture of what has been happening to our wildlife.
One thing is quite clear now. Our forests, or for that matter whatever is left, can no longer give food and shelter to wildlife. The animals are coming out of the little green cover that is left

Amur tigers in population crisis

The effective population of the critically endangered Amur tiger is now fewer than 14 animals, say scientists.
Approximately 500 Amur tigers actually survive in the wild, but the effective population is a measure of the genetic diversity of the world’s largest cat.
Very low diversity means any vulnerability to disease or rare genetic disorders is likely to be passed on to the next generation.
The findings are

Tiger numbers could triple if large-scale landscapes protected: study

Asia’s tiger reserves could support more than 10,000 wild tigers – three times the current number – if they are managed as large-scale landscapes that allow for connectivity between core breeding sites, a new paper from some of the world’s leading conservation scientists finds.
The study, co-authored by WWF scientists, is the first assessment of the political commitment made by all 13 tiger range countries at November’s historic tiger summit to double the tiger
