''Hysterocrates gigas'' or the Giant baboon spider, is a member of the tarantula family, Theraphosidae. It is also known as the Cameroon red baboon spider. ==Description== This is a burrowing spider and ranges in color from a dull black and gray to a rusty orange/brown. It is black when freshly moulted (post-moult) and turns brown just before a moult (pre-moult). Its eyes are small and weak and only able to judge light levels. Its abdomen is oval in shape with a diameter up to . Although it has hairy legs, this tarantula is an Old World species and does not have urticating hairs on its abdomen. (Urticating hairs are hairs found in most new world species (those from North and South America) that can be shed in defence, they are barbed and may cause severe itching.) It also has a leg span which may reach . This tarantula, in common with the rest of the family, has downward-facing, parallel fangs, used like pickaxes rather than pincers. Adult males have smaller abdomens than females. Male pedipalps are club shaped, but it may take up to 4 years for differences between male and female to show, since the average male lifespan is about 4 years and the leg span of the male is roughly 5”. These tarantulas spin very little silk - what silk they do spin is used for egg sacs or to line their burrows - they do not make webs. These tarantulas in particular burrow very intricate burrows. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hysterocrates gigas」の詳細全文を読む スポンサード リンク
