The development of insect mouthparts from the primitive chewing mouthparts of a grasshopper in the centre (A), to the lapping type (B) of a bee, the siphoning type (C) of a butterfly and the sucking type (D) of a female mosquito.
Head: The head has large compound eyes and, if mouthparts are present, they are almost always a drinking straw-like proboscis. Scales: Scales cover the external surface of the body and appendages. Thorax: The prothorax is usually reduced. Wings: Two pairs of wings are present in almost all taxa. The wings have very few cross veins.
A syrphid fly using its proboscis to reach the nectar of a flower. A proboscis (/ p r oʊ ˈ b ɒ s ɪ s,-k ɪ s /) is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an ...
Forked tongues have evolved in these squamate reptiles (lizards and snakes) for various purposes. The advantage to having a forked tongue is that more surface area is available for the chemicals to contact and the potential for tropotaxis. [5] The tongue is flicked out of the mouth regularly to sample the chemical environment.
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.
Draco is a genus of agamid lizards [1] that are also known as flying lizards, flying dragons or gliding lizards. These lizards are capable of gliding flight via membranes that may be extended to create wings ( patagia ), formed by an enlarged set of ribs.
Chameleons grasp their prey with a projectile tongue. This is made possible by a hyoid mechanism, which is the contraction of the hyoid muscle that drives the tip of the tongue outwards. [33] An eastern blue-tongued lizard preyed upon by an eastern brown snake. Within the subclass Lepidosauria there are herbivores, omnivores, insectivores, and ...
The common agama, red-headed rock agama or rainbow agama (Agama agama) is a species of lizard from the family Agamidae found in most of sub-Saharan Africa.To clear up centuries of historical confusion based on Linnaeus and other authors, Wagner et al. designated a neotype (numbered ZFMK 15222) for the species, using a previously described specimen from Cameroon in the collection of the ...
