Coras (spider)

Coras is a genus of funnel-web spiders in the family Agelenidae. These spiders are found primarily in North America.

Description:

Coras spiders are generally medium to large in size, with a brown or grayish-brown coloration. They possess long spinnerets, characteristic of funnel-web spiders. Their body shape is elongated and slender. Distinguishing features can vary between species within the genus, requiring careful examination for accurate identification.

Habitat and Distribution:

Coras spiders build funnel-shaped webs, typically in dark, secluded locations such as under rocks, logs, or in crevices. They are commonly found in wooded areas and around human dwellings. Their distribution is mainly confined to North America, although specific species may have more restricted ranges.

Behavior:

Coras spiders are ambush predators, waiting within their funnel web for prey to stumble across it. When an insect or other small creature lands on the web, the spider quickly emerges to capture it. They are generally not considered aggressive towards humans.

Taxonomy:

Coras belongs to the family Agelenidae, which encompasses a wide variety of funnel-web spiders. The genus includes numerous species, with taxonomic classifications subject to ongoing research and potential revisions.
