Single-gene and whole-genome duplications are important evolutionary mechanisms that contribute to biological diversification by launching new genetic raw material. For example, the evolution of animal vision is tightly linked expansion opsin gene family encoding light-absorbing visual pigments. In teleost fishes, most species-rich vertebrate group, opsins particularly diverse key successful colonization habitats ranging from bioluminescence-biased but basically dark deep sea clear mountain...
The Paradise whiptail (Pentapodus paradiseus) has distinct reflective stripes on its head and body. contain a dense layer of physiologically active iridophores, which act as multilayer reflectors. wavelengths reflected by these can change from blue to red in 0.25 s. Transmission electron microscopy revealed that the iridophore cells plates are, average, 51.4 nm thick. This thickness produces stack, acts an ideal quarter-wavelength reflector (equal optical spaces) blue, but not red, region...
At depths below 10 m, reefs are dominated by blue-green light because seawater selectively absorbs the longer, 'red' wavelengths beyond 600 nm from downwelling sunlight. Consequently, visual pigments of many reef fish matched to shorter wavelengths, which transmitted better water. Combining typically poor long-wavelength sensitivity eyes with presumed lack ambient red light, is currently considered irrelevant for fish. However, previous studies ignore fact that several marine organisms,...
Luminance vision has high spatial resolution and is used for form texture discrimination. In humans, birds bees luminance channel spectrally selective – it depends on the signals of long-wavelength sensitive photoreceptors (bees) or sum long- middle- wavelength cones (humans), but not signal short-wavelength (blue) photoreceptors. The reasons such selectivity are fully understood. aim this study to reveal inputs cone in reef fish. 16 freshly caught damselfish, Pomacentrus amboinensis, were...
Abstract Two rival theories of how humans recognize faces exist: (i) recognition is innate, relying on specialized neocortical circuitry and (ii) a learned expertise, general object pathways. Here, we explore whether animals without neocortex, can learn to human faces. Human facial has previously been demonstrated for birds, however they are now known possess neocortex-like structures. Also, with much the work done in domesticated pigeons, one cannot rule out possibility that have developed...
Animals often change their habitat throughout ontogeny; yet, the triggers for transitions and how these correlate with developmental changes – e.g. physiological, morphological, behavioural remain largely unknown. Here, we investigated ontogenetic in body colouration of visual system relate to a coral-reef fish. Adult dusky dottybacks, Pseudochromis fuscus, are aggressive mimics that colour imitate various fishes surroundings; however, little is known about early life stages this Using...
Coral reef fish live in a complex world of colour and patterns. If they are to survive need be able correctly identify the things see (e.g. predators, prey) act accordingly flee, feed). This paper investigates whether discrimination is limited ecologically relevant stimuli or fact more adaptable. Our work focuses on damselfish Pomacentrus amboinensis. Within day two capture demonstrated an ability associate arbitrary stimulus with food reward discriminate from distractor matched along...
Over many millions of years, sea creatures have developed a range light reflectance properties. One example is the large variation in patterns and colours fish inhabiting world's coral reefs. Attempts to understand significance colouration been made, but all too often from perspective human observer. A more ecological approach requires us consider visual system those for whom were intended, namely other life. first step sensitivity reef themselves colour. Physiological data has revealed...
Coral reef fish present the human observer with an array of bold and contrasting patterns; however, ability such to perceive these patterns is largely unexamined. To understand this, visual acuity animals - degree which they can resolve fine detail must be ascertained. Behavioural studies are few in number anatomical analysis has focused on estimates ganglion cell density predict coral fish. Here, we report measures for triggerfish Rhinecanthus aculeatus. Acuity was first assessed using a...
Humans typically have a remarkable memory for faces. Nonetheless, in some cases they can be fooled. Experiments described this paper provide new evidence an effect which observers falsely "recognize" face that never seen before. The is chimera (prototype) built from parts extracted previously viewed It known faces of kind confused with truly familiar faces, result referred to as the prototype effect. However, recent studies failed find full effect, one regarded not only familiar, but more...
Little is known about the sensory abilities of elasmobranchs (sharks, skates and rays) compared with other fishes. Despite their role as apex predators in most marine some freshwater habitats, interspecific variations visual function are especially poorly studied. Of particular interest whether they possess colour vision and, if so, role(s) that may play elasmobranch ecology. The recent discovery three spectrally distinct cone types different species ray suggests at least have potential for...
Abstract Studies on the elasmobranch inner ear have focused predominantly a small group of sharks, particularly, carcharhinids. As result, subsequent studies in other species subdivided into two main groups: those typical and atypical carcharhinid sharks. This study proposes different set inner‐ear morphology groupings to previously suggested. The ears from 17 elasmobranchs (representing both sharks rays) are examined this based morphometric data some groups include rays Four now proposed...
While several phylogenetically diverse species have proved capable of learning abstract concepts, previous attempts to teach fish been unsuccessful. In this report, the ability archerfish (Toxotes chatareus) learn concepts sameness and difference using a simultaneous two-item discrimination task was tested. Six were trained either select pair same or different stimuli which presented simultaneously. Training consisted 2-phase approach. phase 1: symbols in did not change, thereby allowing...

Wrasses (Labridae) are the second largest family of fishes on Great Barrier Reef (after Gobiidae) and, in terms morphology and lifestyle, one most diverse. They occupy all zones reef from very shallow flats to deep slopes, feeding a variety fauna. Many wrasses also have elaborately patterned bodies reflect range colours ultraviolet (UV) far red.
