Facts about Biting Jumping Spiders, "Scientific name for Biting Jumping Spider is Opisthoncus mordax". The Biting Jumping Spiders are black in color. They have a pale patch on the head with and are pale on the abdomen. The Biting Jumping Spiders have strong legs and spines on the surfaces of their bodies for trapping prey. They are good day hunters. Instead of building webs like other spiders, they construct silk sacs. The Biting Jumping Spider are known to jump to a height 50 times their body length. They have very good eyesight due to their large eyes.
Biting jumping spiders can spot their prey from about 15 3/4 inches (40 cm) away. This is because of the four layers of receptor cells in each eye. The Biting Jumping Spider grow to a maximum length of 12 mm. The jumping biting spiders produce venom which isn’t life threatening to humans. They are mistaken for being very dangerous but do not even attack unless they feel threatened. The Biting Jumping Spider bite is dangerous to people with allergy to spider venom.
The biting jumping spider live in open places and because they don’t build webs, they stalk prey before they pounce on them with their amazing speeds. The Biting Jumping Spider can catch a prey bigger than its own size. They live in shrubs and trees in open grasslands and fields to enable them spot insects easily.
The Biting Jumping Spider get to maturity during the months of April and May and start mating and later lay their eggs around July. They suspend eggs in their silk sacs.
Biting jumping spiders inhabit Canada, United States and Nicobar Islands. During the day, the Biting Jumping Spiders hide on the ground but at night they hide under rocks. The biting jumping spider has a life expectancy of 2 to 3 years.d.
Biting Jumping Spiders have oversize brains.
In the Biting Jumping Spider the oxygen is bound to "hemocyanin" a copper-based protein that turns their blood blue, a molecule that contains copper rather than iron. Iron-based hemoglobin in red blood cells turns the blood red
Biting Jumping Spiders have two body parts, the front part of the body is called the Cephalothorax-(the thorax and fused head of spiders). Also on this part of the body is the spider’s gland that makes the poison and the stomach, fangs, mouth, legs, eyes and brain. Spiders also have these tiny little leg-type things called (pedipalps) that are next to the fangs. They are used to hold food while the spider bites it. The next part of the Biting Jumping Spiders body is the abdomen and the abdomens back end is where there is the spinnerets and where the silk producing glands are located.
The muscles in a Biting Jumping Spiders legs pull them inward, but the spider can't extend its legs outward. It will pump a watery liquid into its legs that pushes them out. A Biting Jumping Spider’s legs and body are covered with lots of hair and these hairs are water-repellent, which trap a thin layer of air around the body so the Biting Jumping Spiders body doesn't get wet. It allows them to float, this is how some spiders can survive under water for hours. A Biting Jumping Spider feels its prey with chemo sensitive hairs on its legs and than feels if the prey is edible. The leg hair picks up smells and vibrations from the air. There are at minimum, two small claws that are at the end of the legs. Each Biting Jumping Spiders leg has six joints, giving the Biting Jumping Spider 48 leg joints. The spider’s body has oil on it, so the spider doesn't stick to it’s own web.
A Biting Jumping Spiders stomach can only take liquids, so a spider needs to liquefy their food before they eat. They bite on their prey and empty its stomach liquids into the pray which turns it into a soup for them to drink.
The chances of bites from the Biting Jumping Spiders are rated from slim to none. This is because of their fear of humans and due to the fact that they hunt during the day. Basically the biting jumping spider are no threat to humans.
Spiders belong to a group of animals called "arachnids", mites and Scorpions and a tick is also in the arachnid family. An Arachnids is a creature with eight legs, two body parts, no antennae or wings and are not able to chew on food. Spiders are not insects because insects have three main body parts and six legs and most insects have wings.
The Arachnids are even in a larger group of animals called "arthropods" an invertebrate animal of the large phylum Arthropoda, which also include spiders, crustaceans and insects. They are the largest group in the animal world, about 80% of all animals come from this group. There are over a million different species. There are more than 40,000 different types of spiders in the worl
A male Biting Jumping Spider has two appendages called "pedipalps" a sensory organ, instead of a penis, which is filled with sperm and insert by the male into the female Biting Jumping Spider’s reproductive opening.
Spiders do not have a skeletons. They have a hard outer shell called an exoskeleton-(a rigid external covering for the body in some invertebrate animals). The exoskeleton is hard, so it can’t grow with the spider. The young Biting Jumping Spiders need to shed their exoskeleton. The Biting Jumping Spider has to climb out of the old shell through the cephalothorax. Once out, they must spread themselves out before the new exoskeleton will harden. Know they have some room to grow. They stop growing once they fill this shell. Female Biting Jumping Spiders are usually bigger than males.
Female Biting Jumping Spiders lay eggs on a bed of silk, which she creates right after mating. Once the female Biting Jumping Spider lays her eggs, she will than cover them with more silk.
