First Record of Autotomy in the Neotropical Scorpion Ananteris cussinii Borelli, 1910 in Trinidad, W.I.

Rakesh Bhukal


Autotomy is the behaviour whereby an animal voluntarily sheds or discards one or more of its own appendages, usually as a self-defence mechanism, to elude a predator’s grasp or to distract the predator and thereby allow escape. It is observed in a variety of invertebrate and vertebrate taxa (Fleming et al. 2007; Bateman and Fleming 2009), and in some instances the lost body part may be subsequently regenerated. As it pertains to scorpions, autotomy has only been reported to occur in the neotropical buthid Genus Ananteris Thorell, 1981. This paper further adds to this, as it serves as a first report of metasomal autonomy occurring in yet another species, Ananteris cussinii in Trinidad, W.I.
