I've always found spiders to be fascinating with their eight legs and venom injecting fangs.

Spider
Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. , at least 45,700 spider species, and 113 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.
Arachnid
Arachnids are a class (Arachnida) of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. All arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word ("aráchnē"), from the myth of the hubristic human weaver Arachne who was turned into a spider. Spiders are the largest order in the class, which also includes scorpions, ticks, mites, harvestmen, and solifuges. Almost all extant arachnids are terrestrial, living mainly on land.
Tarantula
Tarantulas comprise a group of large and often hairy arachnids belonging to the Theraphosidae family of spiders, of which about 900 species have been identified. This article only describes members of the Theraphosidae, although some other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas". Except in cases of anaphylaxis (severe allergic reaction), no species of tarantula is dangerous to humans, and some species have become popular in the exotic pet trade. Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.
List of dangerous snakes
List of dangerous snakes: Is an overview of the snakes that pose a significant health risk to humans, through snakebites or other physical trauma. The varieties of snake that most often cause serious snakebites depends on the region of the world. In Africa the most dangerous species include mambas, Egyptian cobras, puff adders, and carpet vipers; in the Middle East the species of greatest concern are carpet vipers and elapids; in Central and South America, "Bothrops" (including the terciopelo or fer-de-lance) and "Crotalus" (rattlesnakes) are of greatest concern. In South Asia it has historically been believed that Indian cobras, common kraits, Russell's viper and carpet vipers were the most dangerous species, however other snakes may also cause significant problems in this area of the world.
List of medically significant spider bites
A number of spiders can cause spider bites that are medically important. Almost all spiders produce venom but only a few are classified as "venomous" and able to cause significant harm to humans. Two medically important spider genera have a worldwide distribution—"Latrodectus" and "Loxosceles". Others have a limited distribution. Medical reports have been criticized for poor evidence. In the last century, both white tailed and wolf spiders were considered medically significant, only to be recanted. Only four genera ("Phoneutria", "Atrax", "Latrodectus", and "Loxosceles") are considered medically significant.
Redback spider
The redback spider ("Latrodectus hasseltii") is a species of highly venomous spider believed to originate in the South Australian or adjacent Western Australian deserts, but now found throughout Australia, Southeast Asia and New Zealand, with colonies elsewhere outside Australia. It is a member of the cosmopolitan genus "Latrodectus", the widow spiders. The adult female is easily recognised by her spherical black body with a prominent red stripe on the upper side of her abdomen and an hourglass-shaped red/orange streak on the underside. Females usually have a body length of about , while the male is much smaller, being only long.
Portia labiata
Portia labiata is a jumping spider (family Salticidae) found in Sri Lanka, India, southern China, Burma (Myanmar), Malaysia, Singapore, Java, Sumatra and the Philippines. In this medium-sized jumping spider, the front part is orange-brown and the back part is brownish. The conspicuous main eyes provide vision more acute than a cat's during the day and 10 times more acute than a dragonfly's, and this is essential in "P. labiata"′s navigation, hunting and mating. The genus "Portia" has been called "Eight-legged Cats", as their hunting tactics are as versatile and adaptable as a lion's. All members of "Portia" have instinctive hunting tactics for their most common prey, but often can improvise by trial and error against unfamiliar prey or in unfamiliar situations, and then remember the new approach.

I am scared of spiders but I know they eat a lot of insects. They are good to have around.
