The 50 Strangest Crossings You Have Ever Seen

Green sea snail

This looks like a creature from a science fiction film. Pay particular attention to the colour. The DNA of the elysia chlorotica (green sea snail) contains the genetic material of the algae on which this creature feeds. This then becomes an animal-plant hybrid that can consume and produce its own food. This sounds like child’s play. It will come in handy if this creature is ever very hungry.
