What food do spiders eat?

Spiders are the general name for all species of arachnids of the Arachnida. Except Antarctica, most of them have venomous glands, and most of them feed on insects, other spiders and polypods, and some spiders also feed on small animals. let's take a look at what spiders eat.

What food do spiders eat?

Spiders are carnivorous animals with a wide range of food, most of their food is insects or other arthropods, and sometimes they can prey on animals several times larger than themselves, such as the bird spider in South America, it sometimes preys on birds, mice and so on. But the spider has no upper jaw and does not directly swallow fixed food. When the prey is caught with a net, the venom secreted by the venom gland in the chelate limb is injected into the capture prey to kill it, and the digestive enzymes secreted by the midgut are infused into the tissue of the prey torn apart by the chelate limb, which is quickly broken down into juice and then sucked into the digestive tract.

Predation classification of spiders

1. Netting spiders: the most important feature of netting spiders is their web-forming behavior. Spiders secrete mucus through protuberances at the tip of the silk sac, which condenses into fine silk when exposed to air. The web made of silk is highly sticky and is the main means of predation for spiders. For insects that stick to the Internet, spiders first inject a special liquid jujube digestive enzyme into their prey. This digestive enzyme can make the insect coma, twitch, until death, and liquefaction of the body, after liquefaction, spiders suck food.

2. Wandering spiders: wandering spiders do not form webs, but wander around or in disguise to prey on prey, such as tall spiders.

Feeding characteristics of spiders

1. The great method of turning a corpse: when a spider hunts, it paralyzes its prey with the toxin in its fangs, secretes digestive juice and injects it into the prey to dissolve its prey, and then slowly sucks it up without missing a bit.

2. Self-made fresh-keeping bags: spiders are afraid of light and often form a web in a place that is transparent and ventilated. In addition to being used to net prey, spider silk can also be used as a fresh-keeping bag. Spiders wrap their leftover food in a web and save it for next time.

3. Cleanliness: spiders make a clear distinction between eating, sleeping and pulling places. Domestic spiders generally use the edge of the cage as a garbage station, where they defecate and throw food scraps.

4. Appetites are exquisite: spiders have a strong sense of domain and should be raised alone. Eat only one or two meals a month, and you can go on hunger strike for up to two months. The food is mainly crickets, grasshoppers and other insects, as long as a wet sponge in the cage to replenish water, it can be raised to adulthood (about seven years), do not have to change cages.
