Zer jaten du?

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.

jakin beharrekoa

Datuak

It hunts at night and builds a new small silk nest every day, in under 10 minutes.1

It can spread to new trees and shrubs by releasing a long silk thread that the wind carries, or by ballooning through the air on a silk line.1

It does not spin a web to catch prey. It hunts actively instead.1

Females mate only once and produce their first egg mass about 14 days after mating.1

Mito-hauslea

Mitoa: Cheiracanthium bites cause necrosis, the death of skin and tissue.

Egia: Bites cause only localised swelling.1
