The labial palps borne on the sides of labium are the counterparts of maxillary palps. Like the maxillary palps, the labial palps aid sensory function in eating. In many species the musculature of the labium is much more complex than that of the other jaws, because in most, the ligula, palps and prementum all can be moved independently.
Mandible (insect mouthpart) Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals.
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. [1] 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 ...
The alligator snapping turtle (Macrochelys temminckii) is a large species of turtle in the family Chelydridae. The species is endemic to freshwater habitats in the United States. M. temminckii is one of the heaviest living freshwater turtles in the world. [ 4 ] It is the largest freshwater species of turtle in North America. [ 5 ]
The basal parts of the chelicerae are the two iridescent green mouthparts. The chelicerae (/ kəˈlɪsəriː /) are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or as a type of pincers.
Mandible (arthropod mouthpart) The mandible (from Latin: mandibula or mandĭbŭ-lum, a jaw) [1] of an arthropod is a pair of mouthparts used either for biting or cutting and holding food. Mandibles are often simply called jaws. Mandibles are present in the extant subphyla Myriapoda (millipedes and others), Crustacea and Hexapoda (insects etc.).
In the skull, adult males have longer lower jaws than females, as well as larger occipital crests. [42] The snout is blunt and lacks the beak of other species. [32] The orca's teeth are very strong, and its jaws exert a powerful grip; the upper teeth fall into the gaps between the lower teeth when the mouth is closed.
The strength of their jaws is such that both striped and spotted hyenas have been recorded to kill dogs with a single bite to the neck without breaking the skin. [35] [36] The spotted hyena is renowned for its strong bite proportional to its size, but a number of other animals (including the Tasmanian devil) are proportionately stronger.
