[3] Their head has large and flattened anterior headshields as well as an indentation of unscaled skin between the jaw and ear opening which may be complete or partial[4] – and is the primary diagnostic character used to distinguish Eurydactylodes species.

[3] The jugal bone is large and in contact with the gecko's infraorbital processes[3] while ornamentation upon the dorsal surface of the skull is present.

[2] Covered in numerous small scales,[4] the tail also has pores which are located near the anal opening and are concentrated in a large singular patch.

[3] All digits possess claws[3] which are high at the base, compressed, robust and decurved[5] and feature large, singular expanded pads underneath.

[2] These geckos display diurnality, and choose to perch on the stalks and leaves of plants even in periods of inactivity as opposed to seeking cover.

[9] When threatened or approached, Eurydactylodes geckos may flatten their bodies against substrate, flee, hiss, growl or croak without a physical display or bite without warning.

[9] Such forests are humid with a tropical/subtropical climate,[9] with both high and low rainfall,[5] and offer opportunity for the arboreal geckos to perch on plants[8] including trees, shrubs, vines, sedges, grasses and ferns.

[12] Enlarged endolymphatic sacs along each side of the neck are postulated to act as reservoirs storing calcareous material aiding in egg shell formation[5] – being larger in females and increasing in size and density prior to egg-laying.

[9] The Diplodactylidae family with which Eurydactylodes resides is postulated to have evolved from a primitive gekkonid radiation located in south-east Asian tropics within the upper Cretaceous.

[3] Genera present within the New Caledonia-Loyalty Islands radiation as a result of evolutionary migration include Eurydactylodes, Rhacodactylus, and likely Bavayia.

[3] Eurydactylodes are convergent with Australian diplodactylid genus Strophurus, twig anoles and other gekkonids according to traits involving crypsis, defense, and reproduction.

[2] An additional species E. occidentalis was also described by American herpetologists Aaron Matthew Bauer and Todd R Jackman as well as Ross Allen Sadlier and Anthony Hume Whitaker in 2009.

Expansion of massif nickel mining in Poum, Dôme de Tiébaghi, Kaala and Taom are resulting in the destruction of Maquis vegetation.

[9] Predation by introduced species along the sclerophyll remnants of the western coast of New Caledonia including rodents and feral cats[9] are harmful to Eurydactylodes geckos.

Lower- elevation forests are abundant in the invasive ant Wasmannia auropumctata which are speculated to have a damaging effect on Eurydactylodes populations.

[9] It has been suggested that management of protected areas be undertaken urgently including surveys monitoring Eurydactylodes population size and trends, habitat loss and invasive fire ants.
