FAQ
Frequently Asked Questions
No, it is a highly specialized scientific term used almost exclusively in arachnology (the study of spiders) and related biological fields.
No. Spiders are divided into two main groups: cribellate (possessing a cribellum) and ecribellate (lacking a cribellum). Most spider families are ecribellate.
The calamistrum is a comb-like row of bristles on the metatarsus of the fourth leg. Cribellate spiders use it to comb out and tease the fine silk threads produced by the cribellum to form the hackled band of their capture web.
It derives directly from Latin 'crībellum', a diminutive of 'crībrum', meaning 'sieve'. This perfectly describes its sieve-like structure and function.
