There are only a few documented cases of the use of either tools or substrates (anvils) as pseudotools in fishes. Described here is an anvil behavior of a labrid fish, Thalassoma hardwicke, observed under aquarium conditions. This fish was fed with pellets that are too large to swallow and too hard to break up into manageable bits using jaws only. The observed individual carried a pellet to an anvil to break it up into pieces small enough to be swallowed. This feeding behavior was frequently… Expand

The use of tools by wrasses (Labridae)
Recently, Jones et al. (2011) described the use of a rock as an anvil to crush a bivalve by a wrasse, the blackspot tuskfish, Choerodon schoenleinii. They concluded by underscoring the importance ofExpand
Repository 3-2012 Tool Use in Fishes
Tool use was once considered the sole domain of humans. Over the last 40 years, however, it has become apparent that tool use may be widespread across the animal kingdom. Pioneering studies inExpand
Tool Use in Fishes
TLDR
It is revealed that tool use seems to be confined to a limited number of fish taxa, particularly the wrasse, which may show similarities with the greater than expected number of examples of tool use in primates and corvids amongst mammals and birds, respectively. Expand
Tool use by a temperate wrasse, California sheephead Semicossyphus pulcher.

TLDR
Multiple individuals of a temperate reef fish species were observed using an anvil to crush hard-bodied invertebrate prey, with potential implications for communities regulated by top-down processes. Expand
Cooperative transport in ants (Hymenoptera: Formicidae) and elsewhere
Cooperative transport, defined as multiple individuals simultaneously moving an object, has arisen many times in ants, but is otherwise extremely rare in animals. Here we review the surprisinglyExpand
Frequent visits to various anvils during tool use by the graphic tuskfish Choerodon graphicus (Labridae).
TLDR
This study investigated tool use by the graphic tuskfish Choerodon graphicus in New Caledonia and found that the results provide a foundation for future research on tool use in fishes. Expand
Changing tides: ecological and historical perspectives on fish cognition.
TLDR
The goal is to illustrate the necessity for basing cognitive investigations on the ecological and evolutionary context of the species at hand, and the importance of ecology and the environment in honing a range of sensory systems that allow fish to glean information and support informed decision-making. Expand
Who would have thought that ‘Jaws’ also has brains? Cognitive functions in elasmobranchs
TLDR
Results of these studies indicate that the assessed cognitive abilities in elasmobranchs are as well developed as in teleosts or other vertebrates, aiding them in fundamental activities such as food retrieval, predator avoidance, mate choice and habitat selection. Expand
Rainbow trout discriminate 2-D photographs of conspecifics from distracting stimuli using an innovative operant conditioning device
TLDR
The successful visual discrimination task using this complex operant conditioning device is particularly remarkable and novel for this farmed-fish species, and could be exploited to develop cognitive enrichments in future farming systems. Expand
Tool use by aquatic animals

TLDR
The contrasts between aquatic- and land-based tool users enlighten the understanding of the adaptive value of tool-use behaviour, and the contributing ecological, physiological, cognitive and social factors are examined. Expand

Fische als Feinde tropischer Seeigel
TLDR
Morphological and ethological preadaptation of the fish to alter its preference for other food is essential before it can develop differentiated capture techniques and the ecological significance of the behaviour of fish in the coral reef ecosystem and the alternating influences in the predator-prey-relationship are discussed. Expand
Nest construction by the labrid fish Choerodon jordani (Snyder 1908)
TLDR
The present findings suggest that C. jordani avoids competition for sleeping sites in diurnal coral reef fish by making nests, which is the first such report in labrid fishes. Expand
Tools and brains in birds
TLDR
It is shown that relative size of the neostriatum and whole brain distinguish the true and borderline categories in birds using tools to obtain food or water and that the complex cognitive processes involved in tool use may have repeatedly co-evolved with large brains in several orders of birds. Expand
Foraging and associated behavior by Octopus cyanea Gray, 1849 on a coral atoll, French Polynesia
TLDR
These field observations suggest that octopuses' keen eyesight is used for determining the foraging path, scanning for predators, matching the substrata for crypsis, and finding their way back to their dens. Expand
Changes with Growth in Feeding Habits and Gravel Turning Behavior of the Wrasse, Coris gaimard
Ontogenetic changes in the diet and foraging behavior of the wrasse, Coris gaimard, were studied on shallow reefs at Kuchierabu-jima Island, southern Japan. C. gaimard selected larger prey withExpand
Patterns of foraging in labrid fishes
TLDR
Four major groups of foraging-microhabitat preferences were apparent: neutral foraging and positive selection towards aggregates, dead coral heads, or live coral, with species having a directed foraging mode most frequently selecting more spatially discrete microhabitats. Expand
Cleaning by the wrasse Thalassoma noronhanum, with two records of predation by its grouper client Cephalopholis fulva
The Noronha wrasse Thalassoma noronhanum was recorded cleaning 19 client fish species at Fernando de Noronha Archipelago, o. north–eastern Brazil. The preferred clients were non–dangerous, mostlyExpand
Fish cognition: a primate's eye view
TLDR
It is concluded that more detailed studies on decision rules and mechanisms are necessary to test for differences between the cognitive abilities of primates and other taxa and proposed a variety of fish species that are most promising as study objects. Expand
Traditionality of mating-site preferences in a coral reef fish
TLDR
Mating sites of the bluehead wrasse Thalassoma bifasciatum have remained in daily use over 12 years (four generations) without changing locations and it is shown that experimental replacement of entire local populations led to the use of new sites, which continued to be used after the manipulations. Expand
Archerfish shots are evolutionarily matched to prey adhesion
TLDR
The blow tube is thought capable only of delivering an all-or-none shot of fixed force, but archerfish shoot down an impressive range of different organisms from flies to small lizards and can estimate their absolute size. Expand
