“…In both experiments, we did not see clear evidence of improvement over the course of learning trials. This, combined with ample evidence of associational learning in P. marginemaculatus [74,75,77,78,97], suggests that either our training trials or the period of training were not sufficient for P. marginemaculaus and P. laevifrons to learn the intended associations in our experiments. The trends toward significance in the novel stimulus trials in both experiments may reflect that these novel trials were conducted after more training trials than the trained stimulus trials.…”

“…In addition to the impressive navigational capacities of amblypygids, research has demonstrated that amblypygids are capable of learning and remembering stimuli in multiple sensory modalities. Phrynus marginemaculatus learn to discriminate tactile and visual stimuli and can associate specific stimuli in each modality with an available shelter [61,74]. This species has also been shown to integrate multimodal cues into a single representation of a home refuge-i.e., configural learning [75].…”

Comparative cognition aims to understand the evolutionary history and current function of cognitive abilities in a variety of species with diverse natural histories. One characteristic often attributed to higher cognitive abilities is higher-order conceptual learning, such as the ability to learn concepts independent of stimuli—e.g., ‘same’ or ‘different’. Conceptual learning has been documented in honeybees and a number of vertebrates. Amblypygids, nocturnal enigmatic arachnids, are good candidates for higher-order learning because they are excellent associational learners, exceptional navigators, and they have large, highly folded mushroom bodies, which are brain regions known to be involved in learning and memory in insects. In Experiment 1, we investigate if the amblypygid Phrynus marginimaculatus can learn the concept of same with a delayed odor matching task. In Experiment 2, we test if Paraphrynus laevifrons can learn same/different with delayed tactile matching and nonmatching tasks before testing if they can transfer this learning to a novel cross-modal odor stimulus. Our data provide no evidence of conceptual learning in amblypygids, but more solid conclusions will require the use of alternative experimental designs to ensure our negative results are not simply a consequence of the designs we employed.

“…The eyes of amblypygi may sense light intensity flux but unlikely to form image (Weygoldt, 2000; Lehmann et al, 2018), as such they rely on non-visual perception of the environmental variables including substratum characteristic, mates and prey by investing in chemo-mechanoreceptors and olfactory sensilla concentrated on the distal articles of the antenniform legs, that continually 'palpate' the surroundings. The role of olfactory cues in navigation (Bingman et al, 2017) and the significance of visual inputs for shelter recognition have been recently recognized (Flanigan et al, 2021).…”

Amblypygi have a tropical and sub-tropical distribution and their first of the four pairs of legs, is modified as feelers. Their activity period and dark habitats render visual cues ineffective and they rely on non-visual sensory perception. There is agreement among researchers that the whip spiders invest in olfactory and tactile senses imparted by sensory structures concentrated on the tarsal segment of the first pair of long, well-articulated non-ambulatory legs that are constantly moved in all directions to sample the environment for detecting location of prey, as also for navigating. This is the first attempt to elucidate the sensory structures present on the antenniform legs of the whip spider, Phrynichus phipsoni (Pocock, 1894), collected from the state of Goa, India; using scanning electron micro[1]scope, and paves way for further research on sensory biology of this cryptic arachnid order. The examined specimen generally conforms to the diversity and morphology of sensory assemblage on the antenniform legs reported in other amblypygi species. Sensory structures elucidated include terminal trident tarsal claws, tarsal organ, bristles, porous sensilla, club sensilla, rod sensilla, slit sensilla, trichobothria, plate organ, pit organ and foliate leaf like hairs.
