are Pleurothallis and Odontioda both types are orchids?
Odontioda Odontioda is a nothogenus of hybrid orchids, for plants produced by crosses between the genera "Odontoglossum" and "Cochlioda". Typically they prefer warmer temperatures and indirect sunlight.
Odontodactylus Odontodactylus is a genus of mantis shrimp, the only genus in the family Odontodactylidae. Mantis shrimp of the genus "Odontodactylus" can not only detect circular polarisation of light, but can polarise light reflecting off their telson and uropods.
