Lamellae on a gecko's foot. In surface anatomy , a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. Aside from respiratory organs, they appear in other biological roles including filter feeding and the traction surfaces of geckos .
Snout longer than the distance between the eye and the ear-opening, 1.5 times the diameter of the orbit; forehead concave; ear-opening rather large, suboval, vertical. Body and limbs stout. Digits free, inner well developed, strongly dilated; with straight transverse lamella beneath; 11 or 12 under the inner digits, 13 to 15 under the median.
The interactions between the gecko's feet and the climbing surface are stronger than simple surface area effects. On its feet, the gecko has many microscopic hairs, or setae (singular seta), arranged into lamellae that increase the Van der Waals forces - the distance-dependent attraction between atoms or molecules - between its feet and the surface.
Hemidactylus is a genus of the common gecko family, Gekkonidae. [3] [4] It has 195 [5] described species, newfound ones being described every few years.These geckos are found in all the tropical regions of the world, extending into the subtropical parts of Africa and Europe.

An example of a scaled mammal is the pangolin. Its scales are made of keratin and are used for protection, similar to an armadillo 's armor. They have been convergently evolved, being unrelated to mammals' distant reptile-like ancestors (since therapsids lost scales), except that they use a similar gene.
