WASHINGTON: Scientists have identified the world’s smallest snake — a reptile about 4 inches (10 cm) long and as thin as spaghetti that was found lurking under a rock on the Caribbean island of Barbados.

The new species, named Leptotyphlops carlae, is smaller than any of the other 3,100 previously known snake species, according to Pennsylvania State University biologist Blair Hedges, who also had helped find the world’s smallest frog and lizard.

It is one of about 300 different species of threadsnake and is a dark brownish gray with two yellow stripes, Hedges said.

It was determined to be a newly identified species due to genetic differences from other snakes and its unique colour pattern and scales, he said.

The snake, which is not venomous, eats termites and termite larvae but little is known about its behaviour, including whether it is nocturnal, Hedges said. It was found in 2006 in a forest on the eastern side of Barbados.

“It was under a rock. We got two of them,” Hedges said in a phone interview. “It’s about as wide as a spaghetti noodle.”—Reuters
