"Spiders don't have nipples!" (You may also be making some rude remarks about whether spiders can ever be cute. There are some people on our team who agree with you on that.) While it's true that spiders do not have nipples, it turns out that T. magnus doesn't actually need them.
Looking closer, they found that during the first week, the mother was depositing droplets of fluid from her underside onto the nest that the hatchlings would come and drink. After the first week, the offspring would drink the fluid directly from the mother's body.
Mother spiders can produce nutritious milk-like fluids to feed their offspring. Juvenile spiders eat all kinds of food: in some spider species they feed on small insects, and in others they catch pollen.
Do spiders lay eggs? Yes, spiders lay eggs. After female spiders mate with males, they keep sperm in a holding place so they can fertilize the eggs. They fertilize the eggs right before laying them.
Spiders are oviparous, which means their babies come from eggs. Spiders will lay between 2 and 1,000 eggs, depending on the species. Almost all female spiders protect their eggs by making a silk 'bed' and then covering them with a silk 'blanket'. She then wraps them in more silk to make the egg sac.
Some spiders have life spans of less than a year, while others may live for up to twenty years. However, spiders face many dangers that reduce their chances of reaching a ripe old age. Spiders and their eggs and young are food for many animals.
Spiders usually have eight eyes (some have six or fewer), but few have good eyesight. They rely instead on touch, vibration and taste stimuli to navigate and find their prey.
In a grisly practice known as sexual cannibalism, females of many spider species devour their mates after procreation, either for sustenance or to keep their reproductive options open. Female spiders are usually much larger than their male counterparts and thus have a strong physical advantage.
Spray them with bleach and water
One of the fastest ways to eliminate pests is bleach. This household compound is so toxic that it kills arachnids and insects in less than five minutes. Sprinkle spider eggs and spiderlings with a mixture of water and bleach.
Male spiders
The testes are located on the underneath of the abdomen, and connect to the surface via a small tube. The male spins a small mat of silk and deposits a 'packet' of sperm from the testes onto the silk mat.
Like all other animals, spiders require a regular intake of water. Different species use different methods to quench their thirst.
Male spiders produce sperm whose cell components are coiled within the sperm cell and that are surrounded by a proteinaceous sheath. These inactive and encapsulated sperm are transferred to the female spermathecae where they are stored for later fertilization.
In Latin America, there lives a unique spider called Bagheera kiplingi. It's a jumping spider and it shares the group's large, acute eyes and prodigious leaping ability. But it also has a trait that singles it out among all 40,000 species of spider – it's mostly vegetarian.
The spider's fangs are rinsed with water to remove sand or dirt. A mild, non-lethal electrical shock stimulates the spider, causing it to produce venom. The venom is collected from the tips of the fangs in a glass capillary tube. The spider regurgitates digestive fluids (it vomits) during milking.
Spiders excrete thick, liquid droppings from their anal opening which land on the surface below. Spider droppings are a combination of digested food (insects) and waste products. The droppings look like pin head-size splats or drips in shades of white, gray, brown, or black.
functata is a cockroach species known to give birth to live offspring. It has the ability to produce milk in the form of a substance containing protein crystals that serves as nutrition for its young.
Spider eggs provide a highly nutritious source of food for the larvae of many species of wasps, flies and mantispid lacewings. Wasps and flies use their long ovipositers to penetrate into the egg sac and lay their eggs among those of the spider.
Spider eggs are surrounded by a hard shell that protects the developing embryo - just like a chicken. The composition of the shell has not been well characterized.
Spider Egg Sacs
If you see a small, usually white or off-white, ball in a spider web or attached to a wall with webbing, it may be a spider egg sac. Spiders lay hundreds of eggs in a single egg sac. So if you see a sac, consider it an early warning sign of the coming infestation once those babies hatch.
Cannibalism is a heritable trait in these spiders, with some families more prone to it than others. Some spiders, such as Pholcus phalangioides, will prey on their own kind when food is scarce. Also, females of Phidippus johnsoni have been observed carrying dead males in their fangs.
Spider eyes for spider lives
They usually have eight eyes: two very large front eyes to get a clear, colour image and judge distance, and extra side eyes to detect when something is moving.
Males ejaculate onto ready-made small sperm webs and then transfer their sperm to syringe-like structures on the tips of their front appendages, or palps. As courtship progresses for the male jumping spider, he will arch his body, and slink on tiptoe toward the female.
Many spiders may also have a crude form of color vision, but for them it's usually based on green and ultraviolet light, which extends their vision into the deep violet end of the spectrum beyond what humans can see, and covers the blue and purple hues in between.
Generally, spiders want to avoid humans and will only bite as a defense mechanism if they are provoked. Many are extraordinary at hiding or camouflaging themselves because they don't want to be seen.
Spiders do not sleep in the same way that humans do, but like us, they do have daily cycles of activity and rest. Spiders can't close their eyes because they don't have eyelids but they reduce their activity levels and lower their metabolic rate to conserve energy.
