The Paraguaian hairy dwarf porcupine, Coendou spinosus, is a South American porcupine species from the family Erethizontidae. It is found in Argentina, Brazil, Paraguay and Uruguay.
The thorny lanternshark is a shark of the family Etmopteridae found in the western Indian Ocean between latitudes 0° and 31°S, at depths between 200 and 500 m. Its length is up to 27 cm.
The Lima leaf-toed gecko has been registered in six archeological sites in Lima, Peru, where it is endemic. It is considered a species in critical danger.
Acanthixalus spinosus is a species of frog in the family Hyperoliidae, the sedge and bush frogs. It is native to Africa, where it can be found in southeastern Nigeria and south- and eastward to Cameroon, Gabon, the Democratic Republic of the Congo, and the Republic of the Congo. It is also presumed to occur in the intervening/adjacent countries of Angola, Equatorial Guinea, and the Central African Republic. Common name African wart frog has been coined for this species.
Temnothorax brunneus is a species of ant in genus Temnothorax, that can be found in Algeria and Morocco.
Temnothorax kutteri is a species of ant in the genus Temnothorax. It is native to southern France and eastern Iberia, from the Pyrenees to the Sierra Nevada. The species parasitises other ant species in the genus Temnothorax.
Temnothorax muellerianus is a species of ant in the genus Temnothorax.
Temnothorax tarbinskii is a species of ant in the genus Temnothorax, that is native to Kyrgyzstan.
Temnothorax inquilinus is a species of ant in the genus Temnothorax native to Ukraine.
Temnothorax tramieri is a species of ant in the genus Temnothorax, that is native to Morocco.
Temnothorax zabelini is a species of ant in the genus Temnothorax, that is native to Turkmenistan.
Leptothorax recedens is a species of ant in the family Formicidae. It is found in France, Italy, and Spain, with the most recent finding in Slovenia.
Myrmoxenus is a genus of ants in the subfamily Myrmicinae. The genus was synonymized under Temnothorax by Ward et al. (2015), but the change was not accepted by Heinze et al. (2015) due to insufficient available data.
Temnothorax americanus is a species of slave-maker ant in the genus Temnothorax. The ants are 2–3 mm in size, and endemic to the northeastern United States and adjacent Canadian regions. They do not forage for food, but instead 'scout workers' from the colony seek out nearby host colonies of ants, steal larvae and bring them back to their own colony. A small T. americanus colony could consist of a queen, two to five workers and thirty to sixty slaves.
Tandem running is a social learning phenomenon seen mostly in ants, by which one ant leads another native ant from the nest to the food source it has found. Tandem running is also used to find and choose better, new nest sites to which the colony can emigrate. The follower ant maintains contact with the lead ant by frequently touching the leader's legs and abdomen with its antennae. As predators, scavengers, and herbivores, ants have a variety of food sources, for which they may journey as far as 200 meters from their nest, spraying a scent trail as they go. To lead their kin to new food sources, ants demonstrate one of the few examples of interactive teaching outside of the mammalian class. Social learning by teaching requires that the naive observer change its behavior and acquire some skills or knowledge faster than it would have independently and that the teacher incur some cost. In order for the follower ant to learn landmarks, the leader must travel much slower and make frequent stops to check for his follower. Ultimately, the knowledge of the route to the new food source can be passed throughout the colony as one follower becomes a leader, making tandem running an effective time-saving practice.

Nigel R. Franks is an English emeritus professor of Animal Behaviour and Ecology at the University of Bristol. He obtained a BSc and PhD in biology at the University of Leeds. After receiving his BSc in 1977 he began his PhD, during which he spent two years doing field work in Panama on army ants with the Smithsonian Tropical Research Institute. He was awarded the Thomas Henry Huxley Award in 1980 from the Zoological Society of London for the best British PhD in Zoology. He then received a Postdoctoral Fellowship from the Royal Commission for the Great Exhibition of 1851 allowing him to undertake postdoctoral work under Edward O. Wilson at Harvard University before becoming a lecturer at the University of Bath in 1982, later being promoted to full professor in 1995. He moved to the University of Bristol in 2001. He is renowned for his studies of collective animal behaviour, particularly of ant colonies. His Ant Lab at Bristol pioneered the use of Temnothorax as a model ant species for the study of collective decision-making and complex systems. In a 2009 profile in Science he discusses his pioneering use of radio-frequency identification tags (RFID) glued to the backs of each ant for tracking individuals in their society. His book Social evolution in ants with Andrew Bourke was an important contribution to the understanding of kin selection theory and sex ratio theory with respect to social evolution in insects, while his co-authored book Self-organization in biological systems has been cited well over 3000 times
Temnothorax lichtensteini is a Mediterranean species of ant in the genus Temnothorax.
