As of official launch you don't seem to be able to find them in the safe shallows close to the aurora crash site. However you CAN find one just below the waterline on the beach behind the quarantine enforcement platform (From which you can grow extra samples), which is probably one of the most accessible spots in the early game.

They are of course extremely common in some of the deeper biomes besides that.
