1Scientists say they have rediscovered in Africa a small creature related to the elephant that disappeared about 50 years ago.
2The mouse-sized animal, called the Somali sengi, is also known as an elephant-shrew.
3It is distantly related to elephants, aardvarks and manatees.
4Researchers say sightings of the Somali sengi species had not been reported for at least 50 years.
5But a search team led last year by international wildlife experts found that the animals were alive and well in the small East African country of Djibouti.
6The team recently reported its results in the publication PeerJ.
7Although the species was only known to live in Somalia,
8the researchers had received information that it might also be in Djibouti.
9Scientists thought the Somali sengi had disappeared in the 1970s.
10There are only 39 individual specimens held in natural history museums around the world.
11Those individuals were the only physical evidence that the animal had ever existed.
12The Global Wildlife Conservation group had included the Somali sengi on its "25 most wanted lost species" list.
13Houssein Rayaleh is with the Association Djibouti Nature.
14He helped lead the search operation.
15In Djibouti, he said they met local people who were able to identify the animal from pictures.
16Rayaleh said he too had seen sengis during his 21 years of doing fieldwork in the country.
17But he and other researchers could never make an official identification.
18"Without formal documentation, the species of the sengis in Djibouti was unknown," he told the French news agency AFP.
19The team set up more than 1,250 traps filled with peanut butter, oatmeal and yeast in 12 places.
20The researchers reported they caught a Somali sengi in the first trap they set.
21"It was amazing," said Steven Heritage, a researcher with Duke University's Lemur Center in Durham, North Carolina.
22"When we opened the first trap and saw the little tuft of hair on the tip of its tail, we just looked at one another and couldn't believe it."
23Heritage noted that a number of small mammal searches since the 1970s had failed to find the Somali sengi in Djibouti.
24"It was serendipitous that it happened so quickly for us," he said.
25For Rayaleh, the find was not all that surprising.
26"For us living in Djibouti, and by extension the Horn of Africa, we never considered the sengis to be 'lost,'" he said.
27"But this new research does bring the Somali sengi back into the scientific community, which we value."
28The team also included global elephant shrew expert Galen Rathburn, who had studied the creatures for many years.
29But Heritage said Rathburn had never before seen a live Somali sengi.
30"So when he opened the first trap and looked over at me, and he had seen the cute tufted furry tail of the animal, he looked at me and said 'I can't believe it, I've never seen one before,'" Heritage told AFP. Rathburn died of cancer shortly after the trip.
31The researchers collected 12 specimens of the animal.
32They said their study proves that the Somali sengi "is currently extant" and lives far beyond the boundaries of Somalia.
33The team is planning a new search to learn more about the species, which it believes could be living across Somalia, Djibouti and Ethiopia.
34The researchers are not able to estimate the size of the population, but they believe the animals are doing well.
35"All the local people knew about this, so it could not be rare in any way," Heritage said.
36Finding a large, living population differs greatly from most organized rescue attempts involving endangered species, said Robin Moore of Global Wildlife Conservation.
37"Usually when we rediscover lost species, we find just one or two individuals," she said.
