Multiple generations of the new creature have been identified in five locations between northern NSW and far north Queensland.whats next.. sharks with fricken lazers on their heads???Posted Image

I just went to look at that link, but unfortunately it contains little information....in fact, none more than the two sentences you have already posted."Hybrid sharks swarming east coast" sounds very sensationalised, but no real supporting information of any kind has been provided.I would be very interested to read a more detailed and factual report if anything is available.

So it's a species of black tipped reef shark (Carcharhinus tilstoni), hybridised with another species of black tipped reef shark (Carcharhinus limbatus).Maybe not as sensational as the reporter from The Australian would have us believe, and Black tipped reef sharks are already known to show large variations in genetic make-up.From my own little knowledge on the subject, hybridisation amongst species is nothing new, and it happens commonly with many different animals. Just look at your own breed of pet dog, or your coloured budgies. In fact, if I were to ever mate with my wife, our offspring would also be a hybrid..........Chinglish! :P Maybe this hybridisation is natures way of ensuring the survival of the species by allowing them to range further, and in turn, being a commercial species it may mean more flake on our plate!Although it's interesting to hear of these finds and this research, I cant say that I have any worries about it, other than how the presence of sharks may affect other species in the food change.
