Abstract Naked mole-rats (Heterocephalus glaber, Rodentia: Bathyergidae) excavate extensive subterranean burrows with their procumbent incisors. Captive individuals often place a wood shaving or tuber husk behind their incisor teeth and in front of their lips and molar teeth while gnawing on substrates that yield fine particulate debris. This oral barrier may prevent choking or aspiration of foreign material. Consistent use of tools has rarely been reported in rodents. 
The Naked Mole-Rat: An Unusual Organism with an Unexpected Latent Potential for Increased Intelligence?
TLDR
It is difficult to envision how naked mole-rats would reach even higher levels of intelligence in their natural sensory-challenged habitat, but such an evolutionary path cannot be excluded if they would expand their range onto the earth’s surface.
How do tufted capuchin monkeys (Cebus apella) understand causality involved in tool use?
Four tufted capuchin monkeys (Cebus apella) were trained to choose from 2 hook-like tools, 1 of which successfully led to collecting food, whereas the other did not because of inappropriate spatial
Tool-use by rats (Rattus norvegicus): tool-choice based on tool features
TLDR
The results suggest that rats understand the spatial and physical relationships between the tool, food, and self when there was no such contradiction.

Tool-use in a display behaviour by Eurasian beavers (Castor fiber)
TLDR
It is suggested that the display, stick display, involving tool use in free-living Eurasian beavers (Castor fiber) is used in agonistic encounters, mainly in a territorial context.
Energetics and burrowing behaviour in the semifossorial degu Octodon degus (Rodentia: Octodontidae)
TLDR
The energetics and burrowing behaviour of the semifossorial Octodon degus were investigated and compared with that of more specialized fossorial rodents, and mass-specific metabolic rate during digging was found to be higher in animals burrowing in soft soils compared to hard soil.
Tool-Use Training in a Species of Rodent: The Emergence of an Optimal Motor Strategy and Functional Understanding
TLDR
It is demonstrated for the first time that rodents can be trained to use tools and suggested that tool use is not a specific faculty resulting from higher intelligence, but is a specific combination of more general cognitive faculties.
‘Captivity bias’ in animal tool use and its implications for the evolution of hominin technology

TLDR
In this review, potential factors contributing to captivity bias in primates (including increased contact between individuals engaged in tool use, guidance or shaping of tool-use behaviour by other tool-users and increased free time and energy) are identified and assessed for their possible effects on the behaviour of the Late Pleistocene hominin Homo floresiensis.
ESTUDO EXPERIMENTAL DO USO DE FERRAMENTAS PARA QUEBRA DE FRUTOS ENCAPSULADOS POR MACACOS-PREGO (Cebus apella) EM SEMI-LIBERDADE
TLDR
Three experiments were conducted about tool use to nutcracking by capuchin monkey (Cebus apella) at semi-free ranging condition in Tiete Ecological Park, and the results confirms the occurrence of this behavior, always involving the simultaneous transport of nuts.
Behavioral task to assess physical causal understanding in rats (Rattus norvegicus)
TLDR
A tool-use task to reveal the evolutionary mechanisms of physical causal understanding in rodents has been offered: a rake-shaped tool was presented in the experimental apparatus without a reward, and one of eight rats could manipulate the rake according to the position of the reward.

Manufacture and use of hook-tools by New Caledonian crows
TLDR
New Caledonian crows Corvus moneduloides are reported on the manufacture and use of two different types of hook tool to aid prey capture: hooked-twig and stepped-cut barbed pandanus leaf.
The Biology of the Naked Mole-Rat
TLDR
An international group of researchers covers such topics as the evolution of eusociality, phylogeny and systematics of the rodent family Bathyergidae, population and behavioral ecology and genetics of naked mole-rats in the field, vocal and nonvocal behaviors, social organization and divisions of labor within colonies, and climatic, social, and physiological factors affecting growth, reproduction, and reproductive suppression.

TLDR
Early anecdotal information and systematic studies of tool use in capuchin monkeys (Cebus spp.) are summarized, indicating that capuchins never develop an understanding of the requirements of the tool tasks presented.
Cooperative Breeding in Mammals: Cooperative Breeding in Naked Mole-Rats: Implications for Vertebrate and Invertebrate Sociality
TLDR
A dual description of H. glaber as cooperatively breeding and eusocial seems redundant, but this dual description is currently necessary because of the apparent divergence between studies of social evolution in vertebrates and invertebrates.
Tool Use in Digger Wasps (Hymenoptera: Sphecinae)
TLDR
Although some have questioned whether the behavior should be considered true tool use, the action clearly falls under the current definition, and when Ammophila uses a pebble as a hammer, she is manipulating an object, not internally manufactured, with the effect of improving her efficiency in altering the position, form or condition of some other object in the environment.
Tool use by wild and captive elephants
TLDR
It is proposed that in elephants, tool use may serve as adaptations enabling these furless, large-bodied tropical land mammals to cope with ectoparasites and thermoregulation.
Snake Mobbing By California Ground Squirrels: Adaptive Variation and Ontogeny
TLDR
Snake mobbing may benefit ground squirrels by reducing the snake's hunting efforts in the area in which mobbing occurred, and natural selection might favor predetermined epigenesis of the ability to recognize and respond appropriately to snakes.
Snake‐directed Behavior by Snake Naive and Experienced California Ground Squirrels in a Simulated Burrow
TLDR
Snake naive and experienced California ground squirrels were video taped while interacting with either a gopher snake or rattlesnake in a simulated burrow dimly illuminated with red light, and olfactory and auditory stimuli from the snake appeared to mediate snake-directed behavior in the burrow.
