An observation of scorpion predation on a gecko in Greece

 

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. 

In a recent paper, Noureddine Benali and Guillaume Gomard have described a case of vertebrate predation from Greece where an Aegaeobuthus gibbosus (Brullé, 1832) (Buthidae) was seen eating on a juvenile gecko Tarentola mauritanica (Linnaeus, 1758). 

The authors think that this is not an isolated case and that opportunistic scorpions will catch and eat any prey they can subdue.

Abstract:
We report a natural case of predation on the gecko Tarentola mauritanica (Linnaeus, 1758) by Aegaeobuthus gibbosus (Brullé, 1832) in Western Peloponnese, Greece. The event was recorded during a nocturnal survey in a sandy habitat. The scorpion was observed grasping the gecko with its pedipalps and feeding on it. This observation provides new insights into the trophic interactions of A. gibbosus.

Amphibians and reptiles as prey of Heteroctenus junceus in Cuba

 

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.
