The round whitefish is different than other whitefish by having one flap between the nostril openings (instead of two). It can grow up to 50 centimetres (20 in) in length [ 6 ] and typically grow in increments of 55–65 millimetres (2.2–2.6 in) annually.
A. Morula and B. cross section of a blastula displaying the blastocoel and blastoderm of early animal embryonic development. Blastulation is the stage in early animal embryonic development that produces the blastula. In mammalian development, the blastula develops into the blastocyst with a differentiated inner cell mass and an outer trophectoderm.

In embryology, cleavage is the division of cells in the early development of the embryo, following fertilization. [1] The zygotes of many species undergo rapid cell cycles with no significant overall growth, producing a cluster of cells the same size as the original zygote.

The division of blastomeres from the zygote allows a single fertile cell to continue to cleave and differentiate until a blastocyst forms. The differentiation of the blastomere allows for the development of two distinct cell populations: the inner cell mass, which becomes the precursor to the embryo, and the trophectoderm, which becomes the precursor to the placenta.

In the broad sense, Coregonus lavaretus, in English referred to as the common whitefish or European whitefish, is widespread from central and northwest Europe to Siberia. [3]
