Arthropods are Animals belonging to the Phylum Arthropoda (from Greek ἄρθρον arthron, " Joint " Arachnids are a class ( Arachnida) of joint-legged Invertebrate Animals in the subphylum Chelicerata. Spiders are Predatory Invertebrate Animals that have two body segments, eight legs no chewing mouth parts and no wings The Araneomorphae are a Suborder of Spiders They are distinguished by having Chelicerae (fangs that point diagonally forward and cross in a pinching action |
The Entelegynae are a subgroup of araneomorph spiders. The Araneomorphae are a Suborder of Spiders They are distinguished by having Chelicerae (fangs that point diagonally forward and cross in a pinching action Almost all members of this group, unlike most members of Haplogynae, have eight eyes, and females have a genital plate. The Haplogynae are a series of araneomorph spiders Unlike the Entelegynae, they lack hardened (sclerotized female genitalia ( Epigynes
However, there are some blind spiders with no or reduced eyes, and six-eyed spiders do occur, for example in the genus Lygromma (Prodidomidae, Gnaphosoidea). As with other animals there are some species of cave-dwelling spiders that have lost their ability to see Lygromma is a spider genus of Central and South America. There are species with eight six (eg The Prodidomidae are a Spider family with about 300 species in 31 genera
This clade contains both cribellate and ecribellate spiders. A cribellum is a kind of comb-like device in certain Spiders used to separate fibers of Silk drawn from its Spinnerets into many extremely fine fibers giving
