Topic Reading-Vol.1151-6/6/2015

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.
