On warm, tropical mudflats, the bizarre Mudwickets, small but oddly-shaped creatures with squat toad-like bodies, bulbous eyes, huge mouths, and flattened bellies, hop from the tide and onto the shore to hunt seaside insects and crustaceans with needle-like teeth and over-sized crunching jaws. Only very distant relatives of the swordwhales, these fish descended not from the swordtails but the guppies; and their evolutionary history has veen very different as well.
