The tip of the tarsus bears claws, which vary in number and size. Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws. Since they do not have antennae, spiders use specialised and sensitive setae on their legs to pick up scent, sounds, vibrations and air currents. [6]
Diagram of a spider leg and pedipalp – the pedipalp has one fewer segment. Arachnid legs differ from those of insects by the addition of two segments on either side of the tibia, the patella between the femur and the tibia, and the metatarsus (sometimes called basitarsus) between the tibia and the tarsus (sometimes called telotarsus), making a total of seven segments.
Male Zoropsis spinimana showing enlarged pedipalps. Pedipalps are composed of six segments or articles. From the proximal end (where they are attached to the body) to the distal, they are: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus.
In the human body, the tarsus (pl.: tarsi) is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot ( cuboid , medial, intermediate, and lateral cuneiform , and navicular ) and hindfoot ( talus and calcaneus ).
They develop within the end segment of the palp (the tarsus), and are only completely visible after the final moult. In some species, apart from carrying the palpal bulb, the tarsus is relatively unchanged. In most species, the tarsus changes shape and forms a hollow structure which surrounds and protects the bulb. It is then called a "cymbium ...
“The hobo spider can inflict a painful bite that results in localized red swelling and some pain, but no necrotic lesion,” Potzler says. Usually, symptoms will get better within 24 hours with ...
The part closest to and attaching the leg to the cephalothorax is the coxa; the next segment is the short trochanter that works as a hinge for the following long segment, the femur; next is the spider's knee, the patella, which acts as the hinge for the tibia; the metatarsus is next, and it connects the tibia to the tarsus (which may be thought ...
Tarsus (plural tarsi; also called telotarsus): Seventh (last) leg segment, after the metatarsus Serrula : A row of tiny teeth along the edge of the maxilla Seta (plural setae): A bristle; [ 22 ] spiders have a variety of hair-like structures of increasing size that are referred to as hairs, bristles (setae) or spines [ 29 ]
