Scientists use food puzzles to show how otters learn from each other

Otters are ready to learn from each other – however nonetheless want to resolve some puzzles on their very own, scientists have discovered.

The semi-aquatic mammals are recognized to be very social and clever creatures, however a examine by the University of Exeter has given new perception into their mind.

Researchers gave otters “puzzle boxes”, a few of which contained acquainted food, whereas others held unfamiliar pure prey – shore crab and blue mussels, that are protected by exhausting outer shells.

For the acquainted food – meatballs, a favorite with the Asian short-clawed otters within the examine – the scientists had 5 several types of bins, and the strategy to extract the food modified in each model, for instance pulling a tab or opening a flap.

The unfamiliar food introduced further issues as a result of the otters didn’t know if the crab and mussels have been protected to eat and had no expertise of getting them out of their shells.

In order to resolve whether or not food was protected and fascinating to eat, the otters, which reside at Newquay zoo and the Tamar Otter and Wildlife Centre, watched intently as their companions inspected what was within the bins and copied if the other otters sampled the treats.

However, they spent extra time attempting to work out how to take away the meat from the shells on their very own and relied much less on the actions of their companions. Of the 20 otters within the examine, 11 managed to extract the meat from all three sorts of pure prey.

“Much of the research into the extractive foraging and learning capabilities of otters has focused on artificial food puzzles,” mentioned the lead creator, Alex Saliveros, of the Centre for Ecology and Conservation on Exeter’s Penryn campus in Cornwall.

“Here, we were interested in investigating such skills in the context of unfamiliar natural prey, as well as in relation to artificial food puzzles.”

Before the check, the group studied the otters’ social teams, that means they knew how nicely they knew each other. They then measured social studying by seeing whether or not shut associates discovered shortly from each other.

Other animals make use of social studying to resolve what’s protected to eat; rats, for instance, want novel food sorts that they’ve smelled on the breath of other rats.

Scientists hope that understanding how otters address unfamiliar foraged food of their pure setting can assist them practice the animals to survive within the wild, if captive-bred otters are to be launched to assist with conservation programmes.

“The captive otters in this study initially struggled with natural prey, but they showed they can learn how to extract the food,” mentioned Saliveros. “Our findings suggest that if you give one otter pre-release training, it can pass some of that information on to others.”
