True or False?  Walking Sharks

It seems like it’s only something for the movies, but it is TRUE, there is such a thing as walking sharks.  Wild, right?  There is a new discovery in the shark world, WALKING SHARKS.  According to the NY Post, “scientists have known about sharks that can “walk” with their fins on dry land for a while, but in researching the known species, they discovered four species that have apparently developed the ability much more recently.”  Granted, this discovery has been made in Northern Australia, and it is a specific shark type only found in that location, so far.  The Marine & Freshwater Research noted that the walking sharks are a part of “the genus Hemiscyllium using a dated molecular phylogeny. The nine currently recognised species in the genus consist of small, benthic sharks that are restricted to the Indo-Australian Archipelago and show limited dispersal at both juvenile and adult stages.”  When you mention the word shark, I’m terrified and intrigued at the same time.  In high school, I studied Marine Biology, and we investigated all marine life, but I was drawn to sharks.  What remember is that sharks have been around for a very long time, “based on fossil scales found in Australia and the United States, scientists hypothesize sharks first appeared in the ocean around 455 million years ago.” (NOAA Fisheries).  Another fact, which is interesting to me that I actually remember from high school, is that sharks have rows of teeth and loose/replace thousands of teeth over their lifespan.
