No, I’m not talking about Sponge Bob or any of his pals! I’m talking about sponges, the real sponges growing on the ocean floor. They are always beautiful, of course, but I had the thrill recently of seeing them spawn!
At first I thought it looked like those ocean vents in the very, very deep ocean, the ones that are smoking with heat from the earth’s core…then I realized, it is sponge sex! Sponges have both eggs and sperm, and can reproduce either way. As to why a sponge decides to send out sperm to fertilize other sponge’s eggs…it is a mystery too deep for me to solve! Here are some gorgeous sponges and enjoy the dive video!
