''A. horridus'', in spite of its habitus, has only been taken on the ground in humus or leaf litter, but it may well be an epigaeic forager, in consonance with its large eyes and long mandibles (Brown 1978).

Gibson et al. (2018) found the [[Morphological_and_Functional_Diversity_of_Ant_Mandibles#Trap-Jaws:_Structure_and_Mechanisms|trap-jaws]] of ''Anochetus horridus'' and ''[[Anochetus emarginatus]]'' have slower strikes relative to the other species of ''Anochetus'' and ''Odontomachus'', reaching mean maximum rotational velocity and acceleration of around 1.3 9 10 4 rad s <sup>-1</sup> and 2 9 10 8 rad s <sup>-2</sup>, respectively. The mass-specific power output of these and other species in these two genera confirm their mandible strikes are power amplified, i.e., in addition to muscle contraction energy, the acceleration of the mandibles is enhanced by mechanical structures that are adapted for, and form part of, their trap-jaws. These species and other measured species in ''Anochetus'' and ''Odontomachus'' follow a pattern of increasingly energetic strikes with larger body mass. This relationship appears to be primarily driven by an increase in mandible mass with larger body size.

Biology

Gibson et al. (2018) found the trap-jaws of Anochetus horridus and Anochetus emarginatus have slower strikes relative to the other species of Anochetus and Odontomachus, reaching mean maximum rotational velocity and acceleration of around 1.3 9 10 4 rad s -1 and 2 9 10 8 rad s -2, respectively. The mass-specific power output of these and other species in these two genera confirm their mandible strikes are power amplified, i.e., in addition to muscle contraction energy, the acceleration of the mandibles is enhanced by mechanical structures that are adapted for, and form part of, their trap-jaws. These species and other measured species in Anochetus and Odontomachus follow a pattern of increasingly energetic strikes with larger body mass. This relationship appears to be primarily driven by an increase in mandible mass with larger body size.
