Dear MEL School’s Topic Readers,
'Virgin-born' sawfish are a first in the
wild
Reproducing alone, or virgin born, does
occur. As was presented in The Lost World, an insightful novel by Michael Crichton
which was also filmed by Spielberg, some species reproduce under extreme
conditions such as captivity or isolation. This time, researchers studied and
concluded such reproduction in being made in the sawfish, critically endangered
ray, in an open sea. The population of this endangered species is so sparse
that finding a mate is an extremely challenging task. The female sawfish might
have left no choice but to reproduce without mating. The virgin born sawfish
the researchers identified are all female. Will this practice avoid extinction?
Enjoy reading thinking the difference of
captivity, isolation and extremely-sparse population.
