Lamela
Lamela adalah plat tipis, yang biasa berjumlah banyak yang saling berdekatan, pada hewan. Selain organ pernapasan, lamela juga terdapat misalnya pada permukaan kaki cecak,[1] dan insang ikan.
Lamela juga dapat merujuk pada lingkaran konsentrik di sekitar kanal Haversian di osteon tulang.[2]

Gecko "feet and toes are a hierarchical system of complex structures consisting of lamellae, setae,and spatulae. The distinguishing characteristics of the gecko adhesion system have been described [as] (1) anisotropic attachment, (2) high pulloff force to preload ratio, (3) low detachment force, (4) material independence, (5) self-cleaning, (6) anti-self sticking and (7) non-sticky default state. ... The gecko’s adhesive structures are made from ß-keratin (modulus of elasticity [approx.] 2 GPa). Such a stiff material is not inherently sticky; however, because of the gecko adhesive’s hierarchical nature and extremely small distal features (spatulae are [approx.] 200 nm in size), the gecko’s foot is able to intimately conform to the surface and generate significant attraction using van der Waals forces.
