what are some special characteristics that make spiders unique in the animal kingdom?

Spider Characteristics All spiders have eight legs, although a few ant-mimicking species use their front legs to imitate antennae, which spiders lack. Spiders are invertebrates (which means they do not have a backbone). They are predatory animals that have no wings and no chewing mouth parts.

Most species of spider are unable to penetrate human or animal skin. Luckily in the U.S., there are only a few spider species whose bite can cause severe problems in people and pets. These are the widow spiders, the brown recluse spider and the hobo spider.

A spider's body has two main sections. A spider's body has two main sections, whereas that of an insect has three sections. Each of the main sections of either an arachnid or an insect's body is known as a 'tagma' (plural 'tagmata'). An insect's body has three main sections: the head, thorax and abdomen.

All spiders and crabs are in the phylum Arthopodia, as are all insects. Arthropods are distinguished physically by the fact that they all have segmented, jointed legs and have an exoskeleton. While both crabs and spiders are grouped in the same phylum, this does not mean that they are necessarily closely related.

Webs are used for trapping prey, but spiders produce silk for other reasons, too. Hunting spiders often make silk to use as drag lines to trail behind them as safety nets while they walk and stalk. Other spiders use a specialized silk to create egg sacs, or even to build a little protective shelter for themselves.

Female Spiders Are Typically Larger The female is significantly bigger than the male in most spider species. ... One theory behind the size difference in male and female spiders is that a larger female body is more advantageous when it comes to generating offspring.

Insects are the usual prey of Redback Spiders, but they are capable of capturing quite large animals, such as male trapdoor spiders, king crickets and small lizards, if they become entangled in the web. Prey-stealing is also common, with large females taking stored food items from others' webs.

Funnel Weaver Spiders These spiders rarely enter homes, but they can be scary when you come across them in your yard or in your garden, especially if you mistake them for the brown recluse. Fortunately, these spiders have hair to help you tell them apart from those brown recluse spiders.

Silverfish, scorpion, dragonfly and prawns are the organisms which belong to the phylum Arthropoda. The characteristic of arthropod is the presence of hard exoskeleton. The exoskeleton is made up of chitin. They have a segmented body and jointed appendages.

Primates (humans and monkeys) appear to be most susceptible, along with guinea pigs and mice. The spider's fangs are bigger than those of a brown snake (which are admittedly small at about 1 cm). The fangs (or chelicerae) are also very sharp and strong. They are allegedly able to pierce a fingernail and shoe leather.

Dolomedes spiders are called fishing spiders because they can run on the surface of water. ... Both groups of these spiders have good vision and hunt their prey aggressively. Wolf spiders do well in captivity if provided with water and prey. Fishing spiders are large, handsome spiders often found near water.

They're arachnids. Just like spiders, scorpions, amblypygids, mites and a bunch of other leggy, land-dwelling animals.

Arachnids are further distinguished from insects by the fact they do not have antennae or wings. Their body is organized into two tagmata, called the prosoma, or cephalothorax, and the opisthosoma, or abdomen.

Determining whether a creature is a vertebrate or invertebrate may not be something you do on a daily basis, but it's worth knowing which creatures are which. The major difference is a backbone: invertebrates lack this bone structure. Spiders happen to be invertebrates, with a slew of their arthropod kin.
