Tarantula
Tarantula
Though all tarantulas are venomous and some bites cause serious discomfort that might persist for several days, so far there is no record of a bite causing a human fatality. In general, the effects of the bites of all kinds of tarantula are not well known. While the bites of many species are known to be no worse than a wasp sting, accounts of bites by some species are reported to be very painful and to produce intense spasms that may recur over a period of several days; the venom by the African tarantula Pelinobius muticus also causes strong hallucinations.
