It is a real shark and is nothing new.The pups live in freshwater and hide among the mangrove swamps and return to the ocean when they grow big enough to fend for themselves.livebearerfreak;3813981; said:so is that really an actual shark??? if it is jeez whats next humans develeping gills to swim with our beloved fish?
They may be the only sharks with this ability.The adults have been known to travel miles upstream which gives them the potential to be quite dangerous.peewee;3814011; said:bullsharks have been doin it for millions of years. it's nothing new.
