A beluga whale stranded in France's River Seine died on Wednesday after a failed rescue mission.
The 800-kilogram cetacean was found stuck in shallow waters north-west of Paris, EuroNews reported.
Veterinarians successfully lifted the 4m-long mammal from the French waterway using a hammock and placed it into a refrigerated truck.
Authorities had planned to keep the whale in the pool for two or three days of treatment before towing it out to sea.
But the dangerously thin white whale began to have breathing difficulties during the rescue attempt, and experts decided to euthanise it, said veterinarian Florence Ollivet-Courtois.
Wildlife website Latest Sightings published incredible footage of an impala that escaped 16 African wild dogs by diving into a dam. It then sidestepped a pod of grumpy hippos.
The footage was captured by ranger Daniel Hitchings, who guided guests at the Thornybush Game Reserve in the Greater Kruger.
They were watching the wild dogs finish off a kill.
The site, which shares wildlife videos from around Africa, also shared the moment a pride of lions came claw-to-claw with a feisty four-inch crab.
The crustacean had unusually come out of its burrow in daylight and was trying to cross a river at the MalaMala Game Reserve in South Africa.
But in a stroke of bad luck, the scuttling crab was spotted by the Kambula pride of lions and lionesses and it sparked their curiosity.
