and you thought fish were fun!
well this one certainly is not when it comes to teeth! photograph Magnus
Kjaergaard/Wikimedia Commons, meet the Lingcod, (Ophiodon elongatus), it has18 canine like teeth and hundreds of others, in fact the Lingcod has 555
teeth razor-sharp, losing up to 20 of them every day and growing them right
back! instead of the incisors, molars, and canines we’re used to seeing, it has
hundreds of nearly microscopic teeth lining its jaws. Their hard palate is also
covered in hundreds of tiny spikes, as are the pharyngeal jaws, a set of
accessory jaws that the lingcod uses to chew its food the way we use our molars, research at
the University of South Florida and the University of Washington set out to learn
more about the lingcod’s tooth-shedding by placing about 20 of them in a tank
filled with a diluted fluorescent dye called alizarin red for 12hours, which
stained the fish’s teeth red. Then they were put in tanks spiked with another
fluorescent dye, calcein fluorescein, which turned new teeth green. So teeth
that were in place one day were red, while those that appeared later were
green,

specimens, coming up with a grand total of 10,580 teeth. Study lead author
Emily Carr also pointed out that the fish seemed to lose an average of roughly
20 teeth per day, but grew them back just as fast, "It blew
our minds that fish were replacing their teeth this quickly,” doctoral student
and co-author Karly Cohen said. “For you and I, that looks like waking up
every morning and losing a single tooth.” the
findings of this study challenge the general notion that teeth are
hard to make and replace. Apparently, for some species, they are just as easily
lost and replaced as hair is for us, now why is it that I do not have teeth like this?
