Archerfish

چکیده
What are archerfish? Members of a family of seven species of perciform fish, all of the genus Toxotes. These opportunistic hunters successfully cope with widely varying environmental conditions and are broadly distributed in mangrove-lined estuaries and freshwater streams of southeast Asia, eastwards from Sri Lanka to Vanuatu (the former New Hebrides) and southwards from the Philippines to Northern Australia.

Competition drives sophisticated hunting skills of archerfish in the wild
Several animals are renowned for their cognitive skills, such as tool use, metacognition or social learning. However, it remains puzzling why some species excel whereas others - sometimes even closely related ones - do not. Archerfish show a remarkable assembly of skills in the context of their unique hunting behavior in which they down aerial prey with shots of water. Hoping to find ecological...
متن کاملA spitting image: specializations in archerfish eyes for vision at the interface between air and water.
Archerfish are famous for spitting jets of water to capture terrestrial insects, a task that not only requires oral dexterity, but also the ability to detect small camouflaged prey against a visually complex background of overhanging foliage. Because detection of olfactory, auditory and tactile cues is diminished at air-water interfaces, archerfish must depend almost entirely on visual cues to ...
متن کاملVisual search in hunting archerfish shares all hallmarks of human performance.
Archerfish are renowned for shooting down aerial prey with water jets, but nothing is known about how they spot prey items in their richly structured mangrove habitats. We trained archerfish to stably assign the categories 'target' and 'background' to objects solely on the basis of non-motion cues. Unlike many other hunters, archerfish are able to discriminate a target from its background in th...
متن کاملConcept learning and the use of three common psychophysical paradigms in the archerfish (Toxotes chatareus)
Archerfish are well known for their specialized hunting technique of spitting water at prey located above the water line. This unique ability has made them a popular focus of study as researchers try to understand the mechanisms involved in targeting and spitting. In more recent years, archerfish have also become an increasingly popular model for studying visual discrimination and learning in g...
متن کاملThe Brain of the Archerfish Toxotes chatareus: A Nissl-Based Neuroanatomical Atlas and Catecholaminergic/Cholinergic Systems
Over recent years, the seven-spot archerfish (Toxotes chatareus) has emerged as a new model for studies in visual and behavioral neuroscience thanks to its unique hunting strategy. Its natural ability to spit at insects outside of water can be used in the laboratory for well controlled behavioral experiments where the fish is trained to aim at targets on a screen. The need for a documentation o...
متن کاملArcherfish use their shooting technique to produce adaptive underwater jets.
Archerfish are renowned for dislodging aerial prey using well-aimed shots of water. Recently it has been shown that these fish can shape their aerial jets by adjusting the dynamics of their mouth opening and closing. This allows the fish to adjust their jet to target distance so that they can forcefully hit prey over considerable distances. Here, we suggest that archerfish use the same techniqu...
