Contrary to what you may think, spiders aren’t insects. They belong to the class of invertebrates known as arachnids. Apart from spiders, mites, ticks and scorpions are animals that belong to this class. Most of them are predatory in nature, and also venomous. One their most obvious differentiating features from insects is the fact that they have 8 legs. Insects only have six. There are an estimated 35,000 to 40,000 species of spiders around the world,better to contact your local pest control Vancouver
Here are a few more fascinating and crazy facts about spiders:
- Spiders don’t have jaws. So to eat, they inject a chemical into their prey that turns their insides into mush. This is what gets sucked in by spiders for their nourishment.
- Inside a spider’s body, spider silk is liquid in form. But when it is exposed to air, it becomes the silky thread we see. These spider threads are secreted by glands located at the tip of their abdomens. Spiders produce more than one type of silk, depending on their purpose as a signal line, a bush web, a sticky silk line to trap prey, or as an aerial web.
- Spiders recycle the webs they spin. They eat the webs to recover some of the proteins they use up in the production process. This silk-producing process is one of the most resource intensive activities a spider undertakes.
- Many types of spiders can walk on water and even stay submerged for lengths of time. Their hairy bodies trap oxygen molecules, which the spiders use to breathe underwater. A National Geographic article reports that some spiders can even survive for several hours underwater by going into a self-induced coma.
- A few years ago, semi-aquatic spiders were discovered attacking and eating fish. Even fish 5 times their size! However, these types of spiders normally have insects as their main diet. But because spiders are predatory, they attack anything that is a potential meal. This behavior has been observed around the world.
- Some species of female spiders have been observed to eat their partners, even during the act. This gave scientists the idea to name this class of spiders widow spiders, as in the black widow. In addition, male spiders do not have penises. Their sexual appendages are located in their face.
- Spider silk is stronger than steel. It’s theorized that if one were able to produce spider silk rope with the thickness of a pencil, this would be strong enough to stop a flying plane cold. Inside a spider’s body, spider silk is liquid in form. But when it is exposed to air, it becomes the silky thread we see.
- The average life of spiders is 1-3 years. Large spiders such as tarantulas have been known to live for decades. Adventurous individuals who care for tarantulas report that these arachnids are “calm and gorgeous” creatures. Getting bitten by a tarantula is not a life threatening event, but will cause pain, redness, and even swelling in the bite area.
- Spiders are blue-blooded creatures. Mammalian blood is red because it binds with hemoglobin (which contains iron). In the case of spiders, their blood binds with the oxidized copper in hemocyanin, giving a pale blue color.
- Spiders are voracious eaters. It is estimated that globally, spiders eat the equivalent of the weight of humans living in England. The presence of spiders in your house is a sign that they are helping you rid your environment of insects and other pests.
