SPIDERS (POECILOTHERIA REGALIS AND P. METALLICA)
The genus Poecilotheria, lives in trees. Members of this genus and also of some others often emit a hissing sound when alarmed. They produce the sound by rubbing certain spines situated on the surface of the basal joint of the fang against others situated on the contiguous surface of the basal joint of the palp. Large, wet-preserved specimens of Poecilotheria metallica and P.regalis are on display.
