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.
Tarentola mauritanica, known as the common wall gecko, is a species of gecko native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands , and the Americas (in Montevideo, Buenos Aires and California).
Body and limbs short. Digits short, free, with very short distal joints, moderately dilated; 5 or 6 lamella under the inner digits, 7 or 8 under the fourth finger, and 8 or 9 under the fourth toe. Snout covered with keeled granules; the rest of the head with smaller granules intermixed with round tubercles.
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.
Gecko toes seem to be double-jointed, but this is a misnomer, and is properly called digital hyperextension. [31] Gecko toes can hyperextend in the opposite direction from human fingers and toes. This allows them to overcome the van der Waals force by peeling their toes off surfaces from the tips inward.
The Indiana Fever continued their offseason overhaul Tuesday by signing free agent forward Brianna Turner, a two-time WNBA all-defensive selection. Turner is the latest addition to a roster that ...
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.
