Enteroctopus is a genus of generally temperate octopuses. Members of the genus Enteroctopus are characterized by their large size and are often known as the giant octopuses. Enteroctopus species have distinct longitudinal wrinkles or folds dorsally and laterally on the body. The head is distinctly narrower than the mantle width. The hectocotylus of the males in this genus, found on the third right arm, is long and narrow in comparison with other genera in the family Octopodidae, often comprising one fifth the length of the arm. Octopuses in this genus have large paddle-like papillae instead of the more conical papillae in other octopus genera. Enteroctopus membranaceus has often been regarded as type species of the genus, not because it was designated as such by Rochebrune and Mabille when they erected the genus, but because it was the first named species in the genus. Robson in his 1929 monograph of octopods regarded E. membranaceus as a species dubium because the original description was insufficient to identify an individual species, the holotype was an immature specimen, and the type specimen was no longer extant. As such, the genus was considered invalid until Hochberg resurrected it in 1998. Hochberg noted that Robson had considered E. membranaceus a junior synonym of E. megalocyathus, the second species assigned to the genus by Rochebrune and Mabille in their 1889 description. Additionally, since Rochebrune and Mabille did not actually assign type status to E. membranaceus, Hochberg concluded that Enteroctopus was indeed a valid genus and transferred type species status to E. megalocyathus by virtual monotypy. The member of this genus that best embodies the common name "giant octopus" is Enteroctopus dofleini, which holds the record of being the world's largest octopus based on direct measurements of a 71-kg (156.5-lb) individual weighed live. This octopus had a total length of 7 m (23 ft). The remaining members of the genus are substantially smaller, with E. megalocyathushaving an average mass of 4 kg and reaching a total length of 1 m.E. magnificus reaches a total length of around 1.5 m.
Poecilotheria regalis is a species of arboreal tarantulas from the Western and Eastern Ghats, India. It is one of the most popular arboreal tarantulas. Their legspan sometimes exceeds 7 inches (18 cm). The name Poecilotheria is derived from Greek "poikilos" - spotted and "therion" - wild beast. Regalis refers to "royal". This whole genus of arboreal tarantulas exhibits an intricate fractal-like pattern on the abdomen. The spider's natural habitat is primarily Southeastern India. The common name for this spider is Indian Ornamental Tree Spider, or simply Indian Ornamental. The P. regalis' behavior parallels that of many arboreal spiders. In the wild the P. regalis live in holes of tall trees where they make asymmetric funnel webs. Their primary prey consists of various flying insects, which they seize in flight and paralyze. It is not unknown for the spiders of this genus to live communally when territory, i.e. number of holes per tree, is limited. They tend to be quite defensive spiders. Although there has never been a recorded death from any tarantula bite this species is considered to have a medically significant bite, with venom that may cause intense pain, judging from the experience of keepers bitten by other spiders from this genus. They move rapidly and, although they generally prefer flight to fight, may attack when cornered.
