I saw this macrophotograph of a limpet’s incredibly gothic teeth. Sorry, make that goethite teeth, apparently incorporating one of the strongest materials known to man. Anyway, it made me think about this poem by the impudent rascal Peter Dance:
I dislike the Limpet
always have and always will
watching it needs overtime
all it does is stay quite still
I so dislike the Limpet
to kill it would be easy
perpetrating such a crime
would not make me feel queasy.
Oh I dislike the Limpet

To which Dance’s outraged fellow members of the Conchological Society of Great Britain and Ireland responded with a torrent of incensed replies (though in one case, including something like a recipe). Go, limpet lovers, go!
Meanwhile, here’s the press release on those wicked teeth. (And let’s just overlook the desperate news office writer–and the scientist!–who want to turn limpet teeth into Formula One race cars; this is a topic worthy of an entirely different kind of outraged poem. The press release–a triumph of biomimicry wannabes over natural history–also neglects to answer the essential question of why limpets need such strong teeth to eat algae.) But I digress:
Limpet teeth might be the strongest natural material known to humans, a new study has found.
Researchers from the University of Portsmouth have discovered that limpets — small aquatic snail-like creatures with conical shells — have teeth with biological structures so strong they could be copied to make
