Photoreceptor projection from a four‐tiered retina to four distinct regions of the first optic ganglion in a jumping spider

The Journal of comparative neurology, 2019
Jumping spiders have four pairs of eyes (ocelli) of which only the principal eyes (PEs) are used to detect features of objects. Photoreceptors in the retina of the PEs form four layers (PL1–4) and terminate in the first optic ganglion (FOG).

Spatial abilities in jumping spiders.

2020
Cognition refers to any state of information processing, including memory, perception, decision-making, and learning. Decision-making, the main component of this thesis, is a cognitive process that allows animals to evaluate their environment so as to avoid less favourable situations.

Extraordinary creatures: jumping spiders

Journal of Experimental Biology
There are almost 7000 species of jumping spider on the planet, with the family comprising 10–13% of all spiders. Found on all continents except Antarctica, they can live at altitudes of up to 7000 m and are even capable of surviving under water, thanks to hydrophobic hairs that hold a bubble of air around the cuticle.

Orientation by Jumping Spiders in the Absence of Visual Feedback

Journal of Experimental Biology, 1971
ABSTRACT Jumping spiders turn to face moving objects. These turns are mediated by the lateral eyes. They can be accomplished accurately whether or not the spider sees the relative movement of the stimulus across the retinae which would normally result from such a turn.
