What Happens to Spiders When They Die?
WouterSpiders are fascinating creatures. They use unique anatomy to power jumps, which are essential to their survival. Some spider species live in aquatic environments, while others are more comfortable in air. However, most of them are predators. So what happens to them when they die?
When a spider dies, its legs curl up. This is due to a failure of its nervous system. Unlike humans, spiders do not have muscles that extend the leg at its joints. In turn, this decreases their ability to climb.
Spiders can also die from a bacterial infection. If a spider is attacked by another creature, it will likely die. Alternatively, it may become weak and die of malnutrition. Lastly, spiders may die from a lack of oxygen. For some species, the oxygen is contained within their hairs. But for most, they require the air in their lungs.
When a spider is laying its eggs, it is in an enclosed chamber. The female Amaurobiidae spiders enclose themselves in this closed chamber to lay its eggs.
The sperm storage organ is located between the book lungs on the ventral side of the abdomen. It is visible as a dark spot on the abdomen.
Some spider species weave webs, which are useful for a variety of activities. Spiders have four to six different types of silk glands. These glands are used to make different types of silk. Silk became valuable for prey capture.
Some species of spiders live in cold climates and overwinter. During winter months, spiders drop their metabolic rate.
