Scieпtists are cultivatiпg aпd studyiпg twο-headed sharks

Scientists are studying a two-headed shark in order to uncover the cause of this rare mutation called dicephaly. The embryo, belonging to the Atlanta saw-tailed cat shark, has two heads, two hearts, two stomachs, two livers, but only one set of intestines, kidneys, and genitals. While previous reports of two-headed sharks have been of the reproductive breed, this is the first egg-laying shark to exhibit this trait, making it a significant discovery. Researchers are keeping the individual to study it closely and understand if having two heads affects its survival or internal organ function. The cause of this genetic variation seems to be mutations and not environmental pollution.
