48-eyed tentacle love

Cubozoa, or box jellyfish, such as these two Copula sivickisi, are the only jellyfish that copulate. They are also unique in having eight camera type eyes, eight slit-shaped eyes and eight lensless pit eyes, all feeding into a simple nervous circuit without a brain. They are active swimmers and engage in eloborate courting rituals.
