“…The authors further argued that the conditions in their experimental tanks (with reflection of waves from the sides of the tank) were not conducive to wake following, and based also on work by Hanke et al (2000) on the wake of a goldfish (Carassius auratus), speculated that fish should be able to derive directional information from wakes as old as 60 s. In a follow-up study, Pohlmann et al (2004) demonstrated that this wake following relied on detection of hydrodynamic disturbance through the lateral line, rather than olfactory cues. Wake following may be widespread among predators that hunt in darkness (including the deep ocean) and in murky waters, and has also been demonstrated in harbour seals (Phoca vitulina) (Schulte-Pelkum et al 2007).…”

I review the evidence that organisms have adaptations that confer difficulty of detection by predators and parasites that seek their targets primarily using sensory systems other than vision. In other words, I will answer the question of whether crypsis is a concept that can usefully be applied to non-visual sensory perception. Probably because vision is such an important sensory system in humans, research in this field is sparse. Thus, at present we have very few examples of chemical camouflage, and even these contain some ambiguity in deciding whether they are best seen as examples of background matching or mimicry. There are many examples of organisms that are adaptively silent at times or in locations when or where predation risk is higher or in response to detection of a predator. By contrast, evidence that the form (rather than use) of vocalizations and other sound-based signals has been influenced by issues of reducing detectability to unintended receivers is suggestive rather than conclusive. There is again suggestive but not completely conclusive evidence for crypsis against electro-sensing predators. Lastly, mechanoreception is highly understudied in this regard, but there are scattered reports that strongly suggest that some species can be thought of as being adapted to be cryptic in this modality. Hence, I conclude that crypsis is a concept that can usefully be applied to senses other than vision, and that this is a field very much worthy of more investigation.

“…In addition to localizing a swimming prey in a dipolar near field, following the wake behind the prey can allow a predator to track and eventually localize the prey, starting at a much greater distance, i.e., a few to a few tens of prey-body length (11,12). A functional lateral line is indispensable for following wake (11,12).…”

Nearly all underwater vehicles and surface ships today use sonar and vision for imaging and navigation. However, sonar and vision systems face various limitations, e.g., sonar blind zones, dark or murky environments, etc. Evolved over millions of years, fish use the lateral line, a distributed linear array of flow sensing organs, for underwater hydrodynamic imaging and information extraction. We demonstrate here a proof-of-concept artificial lateral line system. It enables a distant touch hydrodynamic imaging capability to critically augment sonar and vision systems. We show that the artificial lateral line can successfully perform dipole source localization and hydrodynamic wake detection. The development of the artificial lateral line is aimed at fundamentally enhancing human ability to detect, navigate, and survive in the underwater environment.dipole localization ͉ hot wire anemometer ͉ micromachining ͉ wake detection ͉ neuromast A lateral line is a spatially distributed system of flow sensors found on the body surface of fish (1) and aquatic amphibians (2). It is comprised of arrays of neuromasts, which can be classified into two types: superficial neuromasts and canal neuromasts (Fig. 1). A superficial neuromast is situated on the surface of the fish and responds in proportion to fluid velocity (3, 4). In contrast, a canal neuromast is packaged in fluid-filled canals located beneath the surface of the skin and are commonly described as a detector of outside water acceleration that is proportional to the pressure gradient (1, 3-6). As an integrated flow sensing system, such lateral lines form spatial-temporal images of nearby sources based on their hydrodynamic signatures (1, 3, 5) and provide mechanosensory guidance for many different behaviors, including synchronized swimming in schools, predator and obstacle avoidance, prey detection and tracking, rheotaxis, and holding station behind immersed obstacles in streams (4,7,8). This ''distant touch'' sense complements other sensory modalities, including vision and hearing, to increase survivability in unstructured environments. To date, there has never been an engineering equivalent of the fish lateral line system for underwater vehicles and platforms. The goal of the present research is to build an artificial lateral line that mimics the functional organization and imaging capabilities of the biological one. The artificial lateral line can facilitate fundamental studies of biological systems and provide unprecedented sensing and control functions to underwater vehicles and platforms. Specifically, we envision that the distant touch hydrodynamic imaging capability of the artificial lateral line can provide a new sense in addition to sonar and vision. In this article, we demonstrate the functions of an artificial lateral line under two biologically relevant scenarios: (i) localizing a moving target with flapping part (7, 9, 10) and (ii) imaging a hydrodynamic trail for prey capture (11,12).

“…Experiments to assess the role of prey behavior and habitat complexity on predator-prey fish interactions have a long history in ecology (Savino & Stein, 1982;Juanes et al, 2002), but most theories on this theme have been derived from diurnal predators, while nocturnal piscivores are less studied (Pohlmann et al, 2004;Freitas & Volpato, 2008). High complexity habitats generally reduce predation by providing more prey refuges and reducing encounter rates and foraging efficiency of predators (Savino & Stein, 1982;Almany, 2004).…”

We experimentally examined the predator-prey relationships between juvenile spotted sorubim Pseudoplastystoma corruscans and young-of-the-year invasive and native fish species of the Paraná River basin, Brazil. Three invasive (peacock bass Cichla piquiti, Nile tilapia Oreochromis niloticus, and channel catfish Ictalurus punctatus) and two native (yellowtail tetra Astyanax altiparanae and streaked prochilod Prochilodus lineatus) fish species were offered as prey to P. corruscans in 300 L aquaria with three habitat complexity treatments (0%, 50% and 100% structure-covered). Prey survival was variable through time and among species (C. piquiti < O. niloticus < A. altiparanae < P. lineatus < I. punctatus), depending largely on species-specific prey behavior but also on prey size and morphological defenses. Habitat complexity did not directly affect P. corruscans piscivory but some prey species changed their microhabitat use and shoaling behavior among habitat treatments in predator's presence. Pseudoplatystoma corruscans preyed preferentially on smaller individuals of those invasive species with weak morphological defensive features that persisted in a non-shoaling behavior. Overall, our results contrast with those in a companion experiment using a diurnal predator, suggesting that nocturnal piscivores preferentially prey on different (rather diurnal) fish species and are less affected by habitat complexity. Our findings suggest that recovering the native populations of P. corruscans might help controling some fish species introduced to the Paraná River basin, particularly C. piquiti and O. niloticus, whose parental care is expected to be weak or null at night.A relação predador-presa entre juvenis de pintado Pseudoplatystoma corruscans (piscívoro nativo) e jovens do ano de espécies nativas e invasoras de peixes da bacia do rio Paraná, Brasil, foi testada experimentalmente. Três espécies de peixe invasoras (o tucunaré Cichla piquiti, a tilápia do Nilo Oreochromis niloticus e o bagre do canal Ictalurus punctatus) e duas nativas (o lambari do rabo amarelo Astyanax altiparanae e o curimbatá Prochilodus lineatus) foram oferecidas como presa para P. corruscans em microcosmos, com três tratamentos de complexidade de habitat (0%, 50% e 100% de cobertura por estruturas submersas). A sobrevivência de presas variou ao longo do tempo e entre espécies (C. piquiti < O. niloticus < A. altiparanae < P. lineatus < I. punctatus), sendo governada, em grande parte, por diferenças espécies-específicas no comportamento das presas, mas também pelo tamanho e defesas morfológicas das mesmas. A complexidade de habitat não afetou diretamente a piscivoria de P. corruscans, mas, na presença do predador, algumas espécies-presa alteraram seu comportamento quanto ao uso de micro-habitat e grau de agregação entre os níveis de complexidade de habitat. Pseudoplatystoma corruscans predou preferencialmente sobre os indivíduos menores das espécies invasoras que apresentaram estruturas morfológicas defensivas pouco desenvolvidas e que não formavam cardu...
