A family of killer whales has again become stranded in a silted estuary in Russia's far east just hours after researchers helped the two adults and two calves into deeper water, the emergency ministry said on Thursday.
Russian researchers and volunteers spent all of Wednesday dousing the killer whales with water after they beached in the estuary on the Kamchatka Peninsula and when the tide rose managed to get the orcas to deeper water.
But on Thursday, the family was again stranded, Reuters reported.
"This morning they swam away from the shallow water towards the open sea," the emergency ministry said.
"Sadly, the animals could not find the narrow exit from the estuary and at low tide they found themselves in shallow water again."
One of the orcas was shown by Izvestia lying in shallow water on its side and was distressed.
The newspaper cited an unidentified source as saying the family group might be refusing to swim into the ocean because one of the group was injured and so was unable to go into deeper waters.
Orcas, or killer whales, belong to the sub-order of toothed whales but are also the largest member of the dolphin family, according to Whale and Dolphin Conservation.

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.

Scientists also discovered a spiny mouse, a squirrel, eight types of fish, three amphibians and 10 types of butterflies, Trond Larsen, head of Conservation International's Rapid Assessment Program, told Reuters this week.

He added that another 48 species found by investigators were potentially new, but needed further study.

The new species were found in Alto Mayo, a protected area with several ecosystems, Indigenous territories and villages.

"Discovering so many new species of mammals and vertebrates is really incredible, especially in such a human-influenced landscape as Alto Mayo," Larsen said.

The expedition between June and July 2022 was made up of 13 scientists plus local technicians and members of Indigenous groups.

"It was really fantastic to work so closely with the Awajun people. They have extensive traditional knowledge about the forests, animals and plants they live side-by-side with," Larsen said.

Among the new species, Larsen highlighted the spiny mouse that has stiff fur, the amphibious mouse, and a dwarf squirrel that measures 14 cm (5.5 in).

"(The squirrel) fits so easily in the palm of your hand. Adorable and beautiful chestnut-brown color, very fast," Larsen said. "It jumps quickly and hides in the trees."

Another favorite discovery was the blob-headed fish, a type of armored catfish, he said.

A total of 2,046 species were recorded during the 38-day expedition using camera traps, bioacoustic sensors and DNA sampling. Among them, 49 were classified as threatened, including the yellow-tailed woolly monkey and the tree monkey.

Larsen said the discoveries reinforced the need to protect the area.

"Unless steps are taken now to safeguard these sites and help restore parts of the landscape ... there's a strong chance they won't persist in the long term," Larsen said.
