    Sharks in Australia are evolving to walk on land, because it's Australia

    A number of shark species appear to be actively evolving to use their fins as legs, to walk across land from pool to pool. Be very afraid.

    Pish posh! If they were really Australian they'd be poisonous.

    Isn't venom a poison?

    Well, I think that venomous is usually used for animals like snakes that inject a toxin, while poisonous is used for animals like frogs that only kill you if you lick them.

    I was initially confused by the author's use of "phylum" in that story, and then I realized she needs to learn the difference between phylum and genus. And the genus is Hemiscyllium, not Hemiscyllum.

    Yes indeed, phylum is a very broad classification, in this case chordata, which includes all animals with a spinal cord. I am pretty sure that genus is the preferred classification term for these sharks.

    I wonder.. What kind of venom and poison do you think these sharks will evolve? Because it's Australia, they don't have be limited in respect lethality.

    Video of one of these sharks WALKING on the sea floor, using its four lower fins. Wow.

    I am slightly disappointed by the absence of venom injecting canine teeth.
    A potent protease toxin would be ideal. Something that liquefies a grapefruit sized volume of flesh. OWWWW!!!
    No way I am ever going to the Counterweight Continent. Drop Bears, shudder!
    Not while Kamchatka beckons with its Lahars, bears, rivers of molten rock, CO2 death traps, and bone dissolving acid lakes.
    That peninsula is way under-visited.

    They won't need venom. They'll just mount frickin lasers on their heads.

    I seem to remember some video talking about what bull sharks might evolve into. It is the bull sharks you have to watch for, mostly.
