Jump takeoff in a small jumping spider [PDF]
Journal of Comparative Physiology A, 2021 Jumping in animals presents an interesting locomotory strategy as it requires the generation of large forces and accurate timing. Jumping in arachnids is further complicated by their semi-hydraulic locomotion system. Among arachnids, jumping spiders (Family Salticidae) are agile and dexterous jumpers.

Predatory Behavior of Jumping Spiders
Annual Review of Entomology, 1996Salticids, the largest family of spiders, have unique eyes, acute vision, and elaborate vision-mediated predatory behavior, which is more pronounced than in any other spider group. Diverse predatory strategies have evolved, including araneophagy, aggressive mimicry, myrmicophagy, and prey-specific prey-catching behavior. Salticids are also distinctive

Fine structure of the eyes of jumping spiders
Journal of Ultrastructure Research, 1971The four pairs of eyes in two species of jumping spiders (Metaphidippus harfordi and Phidippus johnsoni) were studied by light and electron microscopy. Unique features of the anteromedial eyes, used in acute vision, are: stratification of receptors (basis of color vision?); rhabdomeres in anterior row of receptors in two planes perpendicular to each ...

Prolonged milk provisioning in a jumping spider
Science, 2018Spider nursery Mammals produce milk to feed their offspring, and maternal care often continues well after the young can forage for themselves. Though other cases of milk-like secretions have been found, this combination of ongoing maternal care has largely been considered a uniquely mammalian trait. Chen et al.

Hypersensitivity in the Anterior Median Eye of A Jumping Spider
Journal of Experimental Biology, 1976ABSTRACT Changes in sensitivity of the photoreceptor cells of the anterior median eye of the jumping spider Menemerus confusus Boes, et Str. have been studied by recording electroretinograms (ERGs) and receptor potentials. The amplitudes of the responses (ERGs and receptor potentials) increase during repetitive stimulation, with a ...

Visual attention and processing in jumping spiders
Trends in NeurosciencesJumping spiders have extraordinary vision. Using multiple, specialized eyes, these spiders selectively gather and integrate disparate streams of information about motion, color, and spatial detail. The saccadic movements of a forward-facing pair of eyes allow spiders to inspect their surroundings and identify objects.

The Jumping Mechanism of Salticid Spiders
Journal of Experimental Biology, 1959ABSTRACT Photographs of the jumping spider Sitticus pubescens (Salticidae) show that the jump is almost entirely due to the sudden straightening of the fourth pair of legs. Multiple-image photographs show the importance of a silk drag-line in controlling the jump. The torques at the leg joints have been estimated. Extension torques occur
