“…As described by Patel & Cronin [5,10], we observed that animals would make tortuous paths away from the burrow until they located the food placed in the arena. After animals located the food, they would usually execute a fairly direct home vector towards the burrow.…”

“…Taken together with our previous work on mantis shrimp navigation [5,10], this work offers an opportunity to study the neural basis of navigation, learning, memory and decision making in stomatopods. Mushroom bodies, centres for arthropod learning and memory, are thought to play a prominent role in landmark learning in insects [30][31][32][33].…”

“…What governs this decision making? Owing to errors inherent in path integration, home vector errors grow with increased outward path lengths [10]. When the landmark was displaced, individuals may have evaluated this accumulated error during foraging, choosing to trust the position of the landmark when the accumulated error of the path integrator was high (i.e.…”

“…Therefore, with longer outward paths, increased positional errors of home vectors are expected [7,9]. As theory suggests, path integration in N. oerstedii is prone to this accumulated error [10]. To overcome this error, many path-integrating animals use landmarks to accurately pinpoint their goal [9,[11][12][13][14].…”

Mantis shrimp commonly occupy burrows in shallow, tropical waters. These habitats are often structurally complex where many potential landmarks are available. Mantis shrimp of the species Neogonodactylus oerstedii return to their burrows between foraging excursions using path integration, a vector-based navigational strategy that is prone to accumulated error. Here, we show that N. oerstedii can navigate using landmarks in parallel with their path integration system, correcting for positional uncertainty generated when navigating using solely path integration. We also report that when the path integration and landmark navigation systems are placed in conflict, N. oerstedii will orientate using either system or even switch systems enroute. How they make the decision to trust one navigational system over another is unclear. These findings add to our understanding of the refined navigational toolkit N. oerstedii relies upon to efficiently navigate back to its burrow, complementing its robust, yet error prone, path integration system with landmark guidance.

“…Furthermore, mantis shrimp of the species Neogonodactylus oerstedii exhibit impressive navigational abilities when returning to their burrows from foraging excursions. These animals use landmarks, if available, in parallel with path integration to quickly pinpoint the location of their burrows ( Patel and Cronin, 2020a , b , c ). The benthic habitats N. oerstedii occupy are abundant with potential visually informative features including sponges, coral, rock and aquatic vegetation: structures of distinct shapes and colors.…”

Mantis shrimp identify an object by its shape rather than its color during visual recognition

Mantis shrimp commonly inhabit seafloor environments with an abundance of visual features including conspecifics, predators, prey, and landmarks used for navigation. While these animals are capable of discriminating color and polarization, it is unknown what specific attributes of a visual object are important during recognition. Here we show that mantis shrimp of the species Neogonodactylus oerstedii are able to learn the shape of a trained target (p=0.048). Further, when the shape and color of a target which they had been trained to identify were placed in conflict, N. oerstedii tended to choose the target of the trained shape over the target of the trained color (p=0.054). Thus, we conclude that the shape of the target was more salient than its color during recognition by N. oerstedii, suggesting that the shapes of objects, such as landmarks or other animals, are important for their identification by the species.
