Hogna wolf spider (family Lycosidae) showing the enlarged posterior median eyes typical of the family. The eyes of spiders vary significantly in their structure, arrangement, and function. They usually have eight, each being a simple eye with a single lens rather than multiple units as in the compound eyes of insects. The specific arrangement ...
Spiders typically have eight walking legs (insects have six). They do not have antennae; the pair of appendages in front of the legs are the pedipalps (or just palps). Spiders' legs are made up of seven segments. Starting from the body end, these are the coxa, trochanter, femur, patella, tibia, metatarsus and tarsus.
Like most spiders the species is sexually dimorphic, the males being distinctly smaller than the females. The body length of the adult male is about 4–5 mm, while that of the female is 6–8 mm. [2] They have eight eyes in total, a pair of two large eyes in front and below them a smaller pair. One pair of medium-sized eyes are high up on the ...
The spider is “thickly” covered in white hairs. It has eight eyes, a wrinkly body and claws on the end of its legs. A photo shows the Godawan palp-footed spider. It has a caramel coloring, a ...
Jumping spiders have eight eyes, the two large ones in the center-and-front position (the anterior-median eyes, also called "principal eyes" [9]: 51 ) housed in tubes in the head and providing acute vision. The other six are secondary eyes, positioned along the sides of the carapace and acting mainly as movement detectors.
The Taiwanese tree-dwelling wolf spider is considered “large,” reaching about 0.8 inches in size, the study said. It has eight eyes, strong legs and a hairy body with a “heart-like” shape.
Caponiidae are unusual in the degree to which the eye number varies. In this they surpass even the family Cybaeidae in which some species have two eyes, some six, and some eight. In some species of the Caponiidae paired eyes meet in the midline, giving the spider in effect, an odd number of eyes. The following genera have eyes as follows:
Jumping spiders have eight eyes, the two large ones in the center-and-front position (the anterior-median eyes, also called "principal eyes" [14]: 51 ) housed in tubes in the cephalothorax and providing acute vision. The other six are secondary eyes, positioned along the sides of the carapace and acting mainly as movement detectors.
