Abstract The retinal structure of three species of nocturnal gecko and two species of diurnal gecko is described. The retinae of nocturnal geckos show some features usually associated with diurnal retinae and those of diurnal geckos features which suggest a nocturnal ancestry.

Recent developments in gecko-inspired dry adhesive surfaces from fabrication to application
Surface Topography Metrology and Properties, 2019The gecko exhibits remarkably swift and reliable climbing ability on most surfaces in nature. Numerous studies have been conducted to determine the underlying mechanisms of gecko adhesion in order to realise controllable gecko-inspired handling ...

Hybrid electrostatic and gecko-inspired gripping pads for manipulating bulky, non-smooth items
Smart materials and structures (Print), 2020We present hybrid electrostatic and gecko-inspired gripping pads that help robots to lift and carry bulky objects. The directional, gecko-inspired adhesive provides a controllable shear force with low normal force, providing a very high effective ...

Gecko adhesion: evolutionary nanotechnology
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008If geckos had not evolved, it is possible that humans would never have invented adhesive nanostructures. Geckos use millions of adhesive setae on their toes to climb vertical surfaces at speeds of over 1 m s−1. Climbing presents a significant challenge for an adhesive in requiring both strong attachment and easy rapid removal.

The Lancet, 2005
A 32-year-old white male presented with a dry cough and a plain chest radiograph showed bilateral hilar lymphadenopathy. 7 years earlier he had had a gecko tattooed on his upper arm, where it lived an unblemished life. At the same time as the cough, the man noted that the animal had developed the macular eruption illustrated in the figure.

Gecko‐Effect Inspired Soft Gripper with High and Switchable Adhesion for Rough Surfaces
Advanced Materials Interfaces, 2019Geckos, which can walk upside down on smooth or rough surfaces, owe this ability to the hierarchical structures under their toes. These structures are responsible for substantial adhesion and, at the same time, for quick attachment/detachment by ...

Parasites in 30 Captive Tokay Geckos, Gekko gecko
Journal of Herpetological Medicine and Surgery, 2004ABSTRACT Twelve species of parasites were recovered from recently imported Tokay geckos, Gekko gecko. These included one cestode species, Oochoristica rachiensis, two trematode species, Mesocoelium monas and Paradistomum geckonum, six nematbde species, Pharyngodon kuntzi, Skrjabinodon sp., Parapharyngodon sp.
