Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Uloboridae
Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body. Description They are medium to large spiders, with tree claws, which lack venomous glands. They build a spiral web using cribellate silk, which is quite fuzzy. They are usually dull in color, and are able to camouflage well into their surroundings. Usually having a humped opisthosoma, which is notoriously more humped than the carapace. Their rear eyes curving, in some species stronger than others. Hunting The hunting method of these spiders is quite unique among all animals in the kingdom. These spiders do not use an adhesive on their orb webs, but rather the very fine cribellate fibers on each strand of silk tend to ensnare prey. Since newly hatched uloborids lack the cribellum needed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
