Facts about Brush-Footed Trapdoor Spiders, "Scientific name about Brush-Footed Trapdoor Spider is Seqocrypta". What should you know about brush-footed trapdoor spider?
These Brush-Footed Trapdoor Spiders are quite common in Australia and the Western Pacific Islands including New Caledonia. The average size of the Brush-Footed Trapdoor Spiders lie between (25 mm to 45 mm) and these are small to average-sized spiders. The Brush-Footed Trapdoor Spiders can be recognized with two brush-feet towards the end of their body and these claw tufts help them climb quickly on vertical surfaces. Their capability to climb glass is quite rare among spiders and it is quite similar to the whistling spider in terms of its climbing capability. Brush-footed trapdoor spider is usually mottled brown or black in color with lots of hair.
Brush-footed trapdoor spiders live in burrows built within the ground, although you can find some of them on trees and they can be recognized with a trapdoor entrance. Their burrows are quite common in suburban gardens and plantations. Western Australia has listed the Brush-Footed Trapdoor Spiders under the short range endemics category, which means the Brush-Footed Trapdoor Spiders are found in limited areas and they might face extinction because of the mining activities.
Mining activities and reducing suburban plantations have endangered this species and it is important to spread awareness about them so that they are not killed on sight. Brush-footed trapdoor spider rarely bites and unless you try to pick it up, it will not harm you.
Brush-Footed Trapdoor Spiders have oversize brains.
In the Brush-Footed Trapdoor 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
Brush-Footed Trapdoor 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 Brush-Footed Trapdoor Spider’s gland that makes the poison and the stomach, fangs, mouth, legs, eyes and brain. Brush-Footed Trapdoor 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 Brush-Footed Trapdoor Spiders body is the abdomen and the abdomens back end is where there is the spinnerets and where the silk producing glands are located.
How to recognize a Brush-Footed Trapdoor Spider?
Do you have an interest in entomology? Entomology is the branch of science concerned with the study of insects and spiders cover a major part of it. Most of the people are afraid of spiders and might even kill it at first sight because of the lack of information about them. However, not all spiders bite until they are mishandled or disturbed and brush-footed trapdoor spider is among on them. How will you recognize this spider? Are you aware of its habitat? Well, if you are don't have any clue about its appearance and size or habitat, you are at the right place.
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 world.
The muscles in a Brush-Footed Trapdoor 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 Brush-Footed Trapdoor 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 Brush-Footed Trapdoor Spiders body doesn't get wet. It allows them to float, this is how some spiders can survive under water for hours. A Brush-Footed Trapdoor 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 Brush-Footed Trapdoor Spiders leg has six joints, giving the Brush-Footed Trapdoor Spider 48 leg joints. The Brush-Footed Trapdoor Spider’s body has oil on it, so the spider doesn't stick to it’s own web.
A Brush-Footed Trapdoor 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.
A male Brush-Footed Trapdoor 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 Brush-Footed Trapdoor Spider’s reproductive opening.
Brush-Footed Trapdoor 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 Brush-Footed Trapdoor Spiders need to shed their exoskeleton. The 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 Brush-Footed Trapdoor Spiders are usually bigger than males.
Female spiders lay eggs on a bed of silk, which she creates right after mating. Once the female Brush-Footed Trapdoor Spider lays her eggs, she will than cover them with more silk.
