arachnid

The scorpion, a Heterometrus spinifer, is completely edible, despite the arachnid being deadly if alive.

The arachnid are followed by the myriapoda (centipedes, etc.), and these by the insecti or true insects.

His comparison of the Arachnid appendages with those of insects and Crustacea is very curious.

Patten considers the Pteraspids as derived from primitive arachnid or spider-like forms having a bony carapace as Limulus has.

The characteristics of the median eyes must then be especially sought for in the arachnid group.

He simply, therefore, substituted Arachnid for Annelid in the old theory.
