Ctenid

Ctenid is a family of comb-footed spiders, also known as ctenids, that are found throughout the world. These spiders are characterized by their comb-like rows of spines on their fourth pair of legs. This comb is used for various purposes, including sensing vibrations, capturing prey, and assisting in silk manipulation. Ctenids are typically nocturnal hunters, often found on vegetation or the ground. Their diets consist mainly of insects and other small arthropods.

The family Ctenidae is diverse, with many genera and species exhibiting a wide range of sizes, colors, and behaviors. Some ctenids are capable of fast movement, earning them the common name "wandering spiders" or "running spiders." They do not build webs to catch prey in the traditional sense, but rather actively hunt or wait in ambush. Their venom is generally not considered medically significant to humans, though some species may deliver a painful bite.

Reproduction in ctenids involves courtship rituals where males often use vibrations and tactile signals to attract females and avoid being mistaken for prey. Females lay their eggs in silken sacs, which they often carry with them or guard in a sheltered location. The young spiders are independent shortly after hatching. Ctenids play a role in controlling insect populations in their respective ecosystems.
