Scorpions prey on a wide variety of invertebrate prey and generally you can say that they will catch and eat any prey they can subdue without to much risk. As most of you probably know, they can catch and eat vertebrate prey too as long as the can subdue them. Cases of predation on amphibians, reptiles and even small mammals have been reported.
Tomás M. Rodríguez-Cabrera and co-workers recently publised an article presenting obervations of the Cuban scorpion Heteroctenus junceus (Herbst, 1800) (Buthidae) catching and eating frogs and lizzards.
Abstract:
Vertebrate predation by scorpions has been scarcely documented in the literature. Contrary to large scorpions of the genera Centruroides, Hadrurus, Opistophthalmus, and Pandinurus from North America and Africa, which are capable of subduing even small rodents and bats, West Indian scorpions of the genera Centruroides, Heteroctenus, and Tityus seem to limit their prey to amphibians and reptiles. Herein we present new cases of a frog (Osteopilus septentrionalis; Hylidae) and three lizards (Anolis allisoni, A. ophiolepis, and A. sagrei; Dactyloidae) preyed upon by Heteroctenus junceus (Herbst, 1800), at the time we summarize all cases of vertebrate predation by scorpions in the region.
