Falcidens is one of three genera within the family Chaetodermatida; its radula consists of a single row of teeth which are mineralized in crystalline hydroxyapatite (a most unusual mineral in organisms), and its teeth are not periodically shed and replaced like in other molluscs.[2] For details of the radula, see Radula#In caudofoveates.

It contains the following species:[3]

Physical constant

Universal and unchanging physical quantity A physical constant, sometimes fundamental physical constant or universal constant, is a physical quantity that cannot be explained by a theory and therefore must be measured experimentally. It is distinct from a mathematical constant, which has a fixed numerical value, but does not directly involve any physical measurement. There are many physical constants in science, some of the most widely recognized being the speed of light in vacuum c, the grav...

Trichromatisme

Un organisme biologique dont la vision se base sur trois types de récepteurs visuels de sensibilité spectrale différente est trichromate. C'est le cas de l'être humain et de plusieurs autres espèces de mammifères. La vision des couleurs dépend de cette base physiologique. Le trichromatisme, la trichromatie ou le trichromaticisme désigne cette organisation de la perception visuelle. Le trichromatisme repose sur la présence, dans la rétine, de trois sortes de photorécepteurs sensible...
