Physical Description and Identification

Adults

Size: Most species are large where females are around 1.0 in (2.54 cm) with a leg span around 3.1 in (1.2 cm)

Color: Each species has different colors, but the common thing is the body color is related to their habitat. Who live in rocky surfaces mostly have brown and grey shades almost camouflaging against the surrounding. Those who live on vegetations have pale stripes throughout the body.

Other Characteristic Features: Their foremost legs have claws that help them move around. Their body is covered with velvety hair.

Fishing Spider Size

Eggs

Female spiders make egg sacs and each one of them has 200-250 eggs. The sacs are then carried by females until the eggs are hatched. Just before the hatching is about to start, the females make a silk web and the sacs are safely deposited on the web.

Spiderlings

After emerging, spiderlings are known to stay 3-7 days on the web and then disperse either by walking or ballooning.

The Web

Spiders of this genus do not build webs for capturing preys.

Are Fishing Spiders Venomous

Fishing spiders can inject venom when they bite, but that is not harmful to human beings as long as individuals are not allergic to spider bites.

Did You Know

  • Although post-mating, all male fishing spiders are eaten by their female counterparts, some do get eaten beforehand as well. Either female spiders fail to recognize them as mates and mistake them for snacks or this could be a way of aggressively rejecting the mating proposal from the male spider. It also depends on female spiders, as they decide which one is more important for them at that point, food or mating.
  • The genus name is a Greek word meaning deceitful.
  • They can figure out if any preys are around them by the vibration on the water surface.
  • Female fishing spiders have extremely good visions.
