he first known virgin births in the wild have been documented among critically endangered smalltooth sawfish in Florida waters. The discovery, reported in the journal Current Biology, marks the first time that living offspring from virgin births -- births where the mother did not mate with a male -- have been found in a normally sexually reproducing animal in nature.
Lead author Andrew Fields explained to Discovery News that “with fragmented habitat and low abundance,” it is likely that female smalltooth sawfish, known for their iconic tooth-studded rostrum or “saw,” are having trouble findings males. Lack of mating can then trigger the unusual births among certain adult females, he and his team suspect. |
