SI NMNH - Jellyfish Romance - (Carybdea sivickisi)

by sbrothier (via)
For most jellyfish, reproduction is not a particularly romantic affair. Typically, males release sperm into the water so that their genetic material can bump into and fertilize eggs released by female jellyfish in a similar fashion. This behavior, known as mass spawning, allows jellyfish to “mate” without the lovers even needing to meet.
