title: [Morphometric invariants of plants, insects and vertebrates].
abstract: The morphometric invariant construction is considered. The invariants are the numbers generated in an axiomatic way. Nonempirical invariants coincide with the empirical ones of various species and are calculated by three functions of two independent variables that are natural numbers. The first function is a quantitative description of well-known spectra of empirical plant invariants in the form of phyllotaxis ratios. The second and the third functions are generated from the first one. They describe quantitatively Insecta and Vertebrata empirical morphometric invariants in the form of double ratio among three linear sizes.
