In studies of bowfin diet, other bowfin were found in the stomach contents (Scott and Crossman, 1973). 1997. It is common that there are eggs in different developmental stages in a single nest. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico.having body symmetry such that the animal can be divided in one plane into two mirror-image halves.
