The world's rarest spider species faces the risk of extinction

This spider species was discovered only twice in Plymouth's old limestone quarry - a British city. However, due to the population development policy here, this rare spider species is in danger of disappearing completely from the world.

They have a habit of deep in the cracks and crevices of limestone, only active at night, of medium size. Due to the discreet habitat, conservationists warned that Nothophantes needed immediate protection.

The name of this spider comes from the Latin origin of only one animal with a horrible, hairy body.

Nothophantes horridus could be pushed into extinction due to housing construction plans on an old limestone quarry in Plymouth.

Nothophantes horridus is an extremely rare species, the first nocturnal spider recorded in 1989, and the second in 1995. Since then there has been no new discovery about this spider.

The final reserve was built to build 57 homes in Plymouth city

Managing the plan at Buglife named Alice Sarr, 33, said: Because this is a very rare spider species, they don't understand why they chose Plymouth as their home.

She said it could be more adaptable to the mild climate on the southern coast. It is possible that they do not have access to other places or their current living places have met the favorable conditions to survive.

Up to 2,000 people signed the letter urging planners to stop construction projects at Plymouth.
