Water spiders survive by carrying an oxygen bubble connected to their body. Adult water spiders range in size from 8 to 15mm and are typically grey to dark brown in color. Their abdomens and legs are covered in a dense covering of fine hairs that act as a sponge, trapping air bubbles in the water and lending them a glittering silver look. These spiders weave underwater web structures that are densely packed with tiny air bubbles, allowing them to remain under for up to 24 hours without needing to resurface.

Water spider habitat

Numerous spider species inhabit areas in or near water, but the water spider, sometimes known as the diving bell spider, lives its entire existence underwater. Due to the bubble of air linked to their bodies, these spiders are incredibly well suited and can survive underwater.

The adaptation of the Water Spider is due to the fierce competition on land and from terrestrial predators. They construct underwater web constructs packed with tiny air bubbles that enable them to remain below for more than 24 hours before needing to resurface.

Water spiders, despite their diminutive size, bite humans. The fangs and venomous jaws of water spiders are used to immobilize their victims. Their bite is said to be unpleasant but not dangerous to humans. In terms of treating any spider bite for which no antivenin is available, there is little that can be done about the toxin. Spider bites are essentially hypodermic injections of toxins, and the toxin does not spurt back out the way a flu vaccine does. Except for some tarantula bites, the fangs are so little that not even a drop of blood comes out, and nothing from the outside will pass down the puncture incision to the toxin.

Thus, the best first aid measure is to cleanse the bite area with cold water. To be on the safe side, soap and water will remove any greasy substance that may be protecting microorganisms in or around the bite site, and it would not hurt to apply some iodine.

Additionally, Water Spider bites result in localized irritation, a minor fever, and vomiting. These will vanish within a few days. Water spider bites are quite rare. You can only be bitten if you are attempting to catch them bare-handed or if they feel threatened or terrified; they rarely bite humans otherwise. The deadly teeth are capable of piercing through human skin. Although the bite is poisonous to fish, all bites to people have been minor. While water spiders are not hazardous, their bites are effective in keeping their victims away. Their existence is dependent on the venom in their bite, which has varying effects on different prey. Apart from that, their physical camouflage aids in their concealment.

Conclusion

Water spiders are capable of biting; however, they are not particularly harmful. They are poisonous and have fangs, but their risk is limited to discomfort and a few other minor symptoms, nothing serious. The fangs are capable of piercing human skin, which is extremely painful. Additionally, the bite results in inflammation and fever in the affected area.
