It is right that 'Dents de requin' means 'Shark Teeth' in french, but are you really sure that it is really the same plants ? 'Dents de requin' is an old clone discovered by Jean-Jacques Labat and I don't know for Shark teeth. Many dionaea are or look the same and have different names, just because different person 'discovered' them ... They are many examples : sawtooth / dentata, alien / Jaw Smiley, cross teeth / degeneration ... There are so many examples ... And many 'clones' are just typical VFT ... The problem in my opinion is that too many people want to make money with dionaea and are ready to do anything for that, giving names to typical or same plants :-(
