Heteropoda maxima is a large member of the Huntsman family and is native to Laos. It is the world's largest spider according to its massive leg span, which can reach up to twelve inches.

Grammostola mollicoma. Another member of the Tarantula family, this spider, prefers the tropical conditions of South America. It lives in the jungles of Paraguay, Uruguay, Argentina, and Brazil. The Brazilian Giant Tawny Red Tarantula is mainly brown with the addition of reddish-orange or pink hairs. The leg span of this large spider can extend to just over ten inches. The female of this species will remain nearby when her young are hatching to assist in their escape from the egg sac.

Lasiodora parahybana is sometimes called the LP or Salmon Pink. It gets its name from the notable presence of salmon pink-colored hairs on its legs, abdomen, and also its mouthparts. This spider inhabits the tropical rainforest regions of Eastern Brazil. The body of the Salmon Pink is bulky, and its legs can span up to ten inches.

Xenesthis immanis is another tarantula native to South America. As suggested by its name, the spider has originated from Columbia. It can grow to a length of almost eight inches to more than eight and a half inches. The Columbian Lesserblack lives in a commensal mutualistic relationship with a species of frog.

Cerbalus aravensis is also a species of the Huntsman spider. It lives in the southern Arava Valley of Israel and Jordon and can grow to five and a half inches.

It is generally a nocturnal spider and generally is more active during the summer months when the weather is hotter.
