My Shark's Tooth grows long, vertical petioles all year long, with larger traps in the summer. The teeth do become shorter the more sun they have. The inner traps also turn only slightly pink.
Dente's grow large traps on very short leaves in the spring, becoming longer in the summer when the Dente characteristic comes through more. They can also have bright red inner traps and red teeth.
Tony's does actually look more like a Dente, mine doesn't grow like that.
