The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) ...
The word arthropod comes from the Greek ἄρθρον árthron ' joint ', and πούς pous (gen. ποδός podos) ' foot ' or ' leg ', which together mean "jointed leg", [4] with the word "arthropodes" initially used in anatomical descriptions by Barthélemy Charles Joseph Dumortier published in 1832. [1]
The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma (cephalothorax). [1] It is a distinctive feature of the subphylum Chelicerata (arachnids, horseshoe crabs and others).
An intriguing arthropod ancestor. The 3D scans revealed two nearly complete specimens of Arthropleura that lived 300 million years ago. Both fossilized animals still had most of their legs, and ...
The mouthparts of arthropods have evolved into a number of forms, each adapted to a different style or mode of feeding. Most mouthparts represent modified, paired appendages, which in ancestral forms would have appeared more like legs than mouthparts. In general, arthropods have mouthparts for cutting, chewing, piercing, sucking, shredding ...
The raptorial foreleg of a praying mantis Mantispid lacewing, showing raptorial forelegs. In biology (specifically the anatomy of arthropods), the term raptorial implies much the same as predatory but most often refers to modifications of an arthropod's foreleg that make it function for the grasping of prey while it is consumed, where the gripping surfaces are formed from the opposing faces of ...
The name Eurypterida comes from the Ancient Greek words εὐρύς (eurús), meaning 'broad' or 'wide', and πτερόν (pterón), meaning 'wing', referring to the pair of wide swimming appendages present in many members of the group. The eurypterid order includes the largest known arthropods ever to have lived.
The arthropod hip–leg joint consists of two parts – the coxa (or the hip) and the trochanter (or the head of the arthropod leg femur). [4] The coxa, in the case of weevils, resembles a nut, and it has a thread running along its inner surface with an angular span of 345°. [2] [4] The trochanter resembles the screw. [4]
