“…As caustic patterns consist of strong fluctuations in the intensity of light, the intensity-based visual systems of teleost fish appear to be impaired by caustic noise, resulting in reduced prey detection (Attwell et al, 2021;Matchette et al, 2020). However, as caustic patterns show little to no modulation in the polarisation of light and therefore barely influence the underwater polarisation scene (Venables et al, 2022), polarisation-sensitive animals, such as crustaceans and cephalopods (Marshall & Cronin, 2014;Shashar, 2014), possess an additional visual channel that is likely to be unaffected by caustic noise (Drerup et al, 2023;Venables et al, 2022). Indeed, caustics reduce the likelihood of cuttlefish (S. officinalis) and crabs (C. maenas) to detect objects that consist of intensity-based cues only; however, object detection is unaffected in caustics when objects contain polarised cues (Venables et al, 2022).…”

“…While caustics reduce the prey detection ability of some predators, such as teleost fishes (Attwell et al, 2021;Matchette et al, 2020), it does not affect the hunting success of all visually guided predators (Drerup et al, 2023), and presumably also does not interfere with the foraging success of predators utilising other sensory channels to localise their prey. Therefore, associating with visually noisy areas may not necessarily be advantageous given the sensory capabilities of the searching predator.…”

Environments contain various forms of noise that can interfere with the ability of animal sensory systems to perceive information. One ubiquitous type of visual noise in shallow aquatic habitats is caustic flicker (or caustics), consisting of dynamically moving light patterns caused by the refraction of light when passing through the water's rippling surface. While some teleost fish avoid environments with caustic noise (where their prey can be more difficult to detect), it remains untested whether caustics affect the habitat selection of invertebrates. In the present study, we ask whether three invertebrate species, the shore crab Carcinus maenas, the brown shrimp Crangon crangon, and the common cuttlefish Sepia officinalis, prefer or avoid associating with environments with caustic noise, and whether caustics affect their behavioural activity and habitat exploration. To do this, we exposed the three species in binary choice experiments to different simulated caustic noise levels varying in their temporal (speed) and spatial (definition) components. Neither of the three tested invertebrate species spent more or less time in environments with higher caustic noise levels. While we also found no evidence that caustics affected the behavioural activity and exploration of Ca. maenas and S. officinalis, the brown shrimp Cr. crangon reduced its activity with increasing spatial caustic noise. However, all obtained effect sizes in this study were small, suggesting that caustic noise only minimally affects invertebrate behaviour. Overall, our results show that, unlike in teleost fish, caustics have limited influence on the habitat selection, exploration, and activity of crustaceans and cephalopods.

Marine animals with polarization vision are able to effectively detect moving objects in shallow waters, which are illuminated by dynamic fluctuations of downwelling light known as caustics. While behavioral studies across different animal species have demonstrated the support of polarization vision in moving object detection within this noisy environment, little is known about how their retinal photoreceptors, absorbing polarized photons, respond to moving objects, or how each photoreceptor contributes to the collective retinal reaction to changes in polarization. In this study, we employed multi-electrode array recordings to examine the retinal neural response of squid to polarized light stimuli that were designed to simulate caustics environment. Extracellular retinal recordings not only exhibit neural activities selective to the direction of polarization but also demonstrate a significant enhancement in response to stimuli with changing polarization compared to constant polarization. This enhancement is robust in almost all recording channels, but absent in a random permutation of the recordings from different trial types. These results suggest that the retinal photoreceptors directly encode the change of polarization stimuli, thereby contributing to signal detections with polarization vision. Together, our research represents a novel neural exploration of cephalopod polarization vision in a caustic environment, and advances our understanding of how nature parses scenes with salient, dynamic polarization in animal vision.
