Is Spiders an Animal?

Spiders are part of the Phylum of Arthropoda. They are a group of invertebrates which have three body parts: the head, thorax, and abdomen. Unlike insects, which have wings, spiders do not.

Almost all spiders have eight eyes, but some have six. There are also a few species with more than eight eyes. Some spiders, such as the brown recluse, are dangerous to humans. In fact, the bite from the brown recluse can be fatal.

Spiders are known to be predators, though they typically only bite if they feel threatened. In addition, many spiders will hunt other spiders. Females may carry young around and help care for them. This behavior is referred to as mating ritual exchange.

Some spiders build a web, which they use to trap prey. Their webs vary in size and shape. They often weave sticky threads into their webs. Some spiders keep a web close to their home so they can nab unsuspecting flies.

Spiders are found on all continents. They are known to live in rainforests, deserts, and shorelines. They come in all shapes and sizes, and some even have bright colors.

There are two major divisions of spiders: the Mesothelae and the Araneida. True spiders are closely related to the Mesothelae suborder.

The Araneida includes the largest order of arachnids. There are over 45,000 species of arachnids in the world. They include spiders, mites, and crustaceans.

Some of the most dangerous arachnids are the black widow and the brown recluse. Both of these species can cause serious wounds.
