Spiders Are Becoming More Aggressive For A Very Worrisome Reason

Spiders Are Becoming More Aggressive For A Very Worrisome Reason

According to a recent study, spiders are becoming increasingly more aggressive... and it's all because of us. More after the jump.

There are several consequences of climate change, but now there is one more. In fact, according to a recent study, climate change could be making spiders more aggressive in response to the changing weather conditions.

Why?

Tropical storms are increasingly violent because of global warming. According to scientists, only the most aggressive spiders can survive in these environments, and these individuals would then transmit this aggressive gene to future generations.

Two smaller eyes bracket two large eyes that rest in the center of their rectangular heads. Those two main eyes are what function like telescopes. Their eyes are basically just immobile lenses, and a long tube extends down from those eyes. This tube is filled with a liquid of some kind that we don't totally understand, but it causes light to bend, essentially functioning as a second lens. The eyes themselves collect and focus light while this liquid spreads it out. This process allows the spiders to see a massive amount of of detail, despite their tiny size. Additionally, the spiders' retinas can swivel on their own, allowing the spider to look around without moving its head.

How could a spider that looks like this do us harm? Well, we could be forcing its hand...

Which spiders does this include?

This study refers to Anelosimus studiosus, a species of spider that lives in North and South America. This species is often affected by storms that can be quite violent. They live in colonies in their three-dimensional webs which can hold up to 100 females. Some spiders are more aggressive than others, but they tend to influence their colony’s overall behaviour.

Aggressive spiders

An aggressive spider will be quicker to defend itself, but also quicker to attack. You can recognise these aggressive specimens since spiders usually only attack classic prey such as small insects, but aggressive spiders might return to their own colony and practice cannibalism as well. This behaviour is becoming more and more common during violent storms caused by climate change.

According to the study, female spiders might also not have the time to take care of their babies, forcing them to develop increased survival skills.
