Pirapatinga pacu fish are giants of the Amazon river that will typically grow to more than seven times the size of the average goldfish! These fish are herbivores with an amazing sense of smell, allowing them to track trees with ripening fruit for miles across the Amazon river ready for the food to drop.
Meet the 'Skywalker' hoolock gibbon, a new species discovered in the rainforests of China.
A team of scientists, led by Fan Peng-Fei from Sun Yat-sen University and including ZSL's Dr Samuel Turvey, used the force (and a comprehensive scientific study of gibbon genetics) to determine that the Skywalker is in fact a completely distinct species of gibbon.
It was named Skywalker because the Chinese characters of its scientific name mean "Heaven's movement" and the primates spend their time high in the rainforest canopy, but also because the team are big fans of the Star Wars films.
We're LIVE with our cetacean strandings expert Rob Deaville ahead of our CSI of The Sea porpoise post-mortem event tonight
Our cetacean strandings expert will be on Facebook LIVE at 2pm today ahead of tonight's unique scientific event, CSI of The Sea.
Tune in for this fantastic opportunity to learn about the Cetacean Strandings Investigation Programme- UK strandings and ask our expert, Rob Deaville, questions about investigating the whales, porpoises and dolphins found stranded every year across UK coastlines before the live post-mortem at 6.30pm!
The first week back of the New Year can be tough. We hope you're having a wonderful, lazy Sunday like this Asiatic lion!
In the wake of the destruction of Typhoon Haiyan, ZSL has been helping rehabilitate mangroves in the Philippines.
Mangrove forests are among the planet’s most biodiverse ecosystems. They are a vital lifeline for marine species and the local communities who rely on them. Find out about our part in this fantastic win for the natural world:
Bactrian camels are amazing animals that can survive in some incredibly harsh conditions but in the wild there are less than 1000 left.
These fantastic creatures can withstand extreme temperatures, can go water-less for weeks at a time and are the only land mammals capable of drinking salt water!
In spite of these marvellous abilities they're Critically Endangered, largely due to loss of habitat and available food. ZSL is working to protect the last remaining populations in Mongolia's Gobi Desert.
Families of wild red foxes have been mysteriously vanishing from a nature reserve in Russia. Looking to unravel the mystery, ZSL’s resident wildlife vet Misha Goncharuk is investigating the disappearances. Find out how:
The destructive power of hurricanes is infamous yet did you know that these tropical storms can actually benefit some young seabirds?
Scientists tracking Round Island petrel seabirds, including ZSL’s Malcolm Nicoll, have discovered that some juvenile birds survive longer where hurricanes appear. One of the theories behind it is that storms force up nutrient rich waters and with them more food.
