Sign in to save

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.

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 three 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. They typically have a humped opisthosoma, which is notoriously more humped than the carapace. Their rear eyes tend to curve, more so in some species than others. Most uloborid spiders have eight eyes, but the genus Miagrammopes has only four.
