In arthropods, an appendage refers to any of the homologous body parts that may extend from a body segment, including antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, locomotor legs (pereiopods for walking, and pleopods for swimming), sexual organs , and parts of the tail . Typically, each body segment carries one ...
Arthropods (/ ˈ ɑːr θ r ə p ɒ d / ARTH-rə-pod) [24] are invertebrates in the phylum Arthropoda.They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated segments, and paired jointed appendages.
The arthropod leg is a form of jointed appendage of arthropods, ... The appendages of arthropods may be either biramous or ... meaning the meeting place of the ...
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.
Antennae (sg.: antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
Newfound fossils of the extinct arthropod Odaraia alata recently provided scientists with a first glimpse of Odaraia’s jawlike structures, called mandibles. These small, paired appendages near ...
Arthropleura had two sets of feeding appendages, the first short and round, and the second elongated and leg-like. The specimens each had 24 body segments and 44 pairs of legs - 88 legs in total.
The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings.
