Odontomachus bauri
''Odontomachus bauri'' is a species of ponerinae ant known as trap jaw ants. The trap jaw consists of mandibles which contain a spring-loaded catch mechanism.
This mechanism permits the ants to accumulate energy before striking or releasing the mandibles rapidly. ''O. bauri'' is known for its powerful mandibles, which can open up to about 180° and within 10 ms of being stimulated and can close within 0.5 ms, which help with catching prey. The mandibles are able to sting and paralyze prey or crush prey to death. ''O. bauri'' also uses its mandibles to propel itself or prey off of the ground either vertically or horizontally. ''O. bauri'' can travel over 20 times their body length in a single jaw-propelled leap. To put this extraordinary ability in relative terms, a human would have to be able to throw its body 13 meters high or 40 meters long to match up to the ''O. bauri’s'' jumps. ''O. bauri'' is closely related to the genus ''Anochetus'' which is in the same family, Formicidae. It has been discovered from southern Costa Rica throughout tropical South America, the West Indies (excpet Cuba and Bahamas), and on the Galapagos Islands.
==Identification==
''O. bauri''‘s main feature is its dark brown color. Additionally, the face to the near margin of vertex is striated. The head is long. There is pubescence or hair on the first gastral tergum and is partially found standing straight up and relatively uniform.〔 The petiolar node (B on Figure 2) is dome-shaped when seen from the side.〔
