Shark Tooth Stalactites
The shark tooth stalactite is broad and tapering in appearance. It may begin as a small driblet of lava from a semi-solid ceiling, but then grows by accreting layers as successive flows of lava rise and fall in the lava tube, coating and recoating the stalactite with more material. They can vary from a few millimeters to over a meter in length.

“Oh, the shark has pretty teeth, dear—

And he keeps it out of sight.”

And called her name, she had heard
It may be, and had not stirred,
That now, it may be, has found
The horn’s sweet note and the tooth of the hound.”
