High Quality Content by WIKIPEDIA articles! Xanthodaphne egregia is a species of sea snail, a marine gastropod mollusk in the family Conidae. There are many definitions of what kind of unit a species is (or should be). A common definition is that of a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not normally happen. Other debatable definitions may focus on similarity of DNA or morphology. Some species are further subdivided into subspecies, and here also there is no close agreement on the criteria to be used.
