Spiders are egg-laying animals; females lay clutches of eggs in a weblike sac. These sacs can house thousands of eggs, and the female spider may simply lay and abandon her eggs, or she may stick around to protect them until they're hatched. Specific reproductive processes may vary by species, but in general, male spiders deposit a sperm web into a female spider's abdominal reproductive organ.Know More
The reproductive process can be potentially dangerous for male spiders. Generally, female spiders are larger than their male counterparts, and they may decide to eat a prospective suitor rather than mate with him. In an attempt to avoid this grisly fate, male spiders may perform a mating dance or some other ritual to appear more appealing as a mate.
Though female spiders do eventually lay their eggs for hatching, the eggs also spend time developing in the female spider's abdomen. After the eggs are laid, they can develop for a week to several months, depending on the spider species and the time of year. Some spider species, such as the Lycosidae, carry their egg sacs around, while others simply lay them on a web or nest. After being hatched, baby spiders will molt — or shed their skins — several times as they develop. Some spider species continue to molt as adults, while others only molt during adolescence.Learn more in Spiders
Spiders communicate by using different levels of vibrations, also called seismic communication, when courting, warning rivals or attempting to catch prey. Some spiders use only the legs to create the vibrations, while others will use a combination of the legs and the abdomen to communicate seismically.Full Answer >
All spiders are carnivorous, which means they eat a variety of insects and other spiders. Large spiders are able to eat small vertebrates like mice and small birds.Full Answer >
Spiders do not have ears, but they do have unique sensory organs that allow them to sense vibrations. According to AskNature.org, certain segments of the spider's legs have tiny hairs called trichobothria, which are incredibly sensitive to vibrations both close and far.Full Answer >
Spiders are arachnids, not insects, although together with insects, they form a group called arthropods, which are animals with hard external shells and jointed legs. The main difference between spiders and insects is body structure.Full Answer >
