Weird but real
Adults have no functional mouth. They live one day to mate, then die. Their nymph stage lasts up to two years underwater.
Why it's cool
Most poetic creature on earth. Their genus name Ephemera is literally where we got the word ephemeral. Mass emergences look like snow falling sideways.
