Nudibranch Egg Ribbon.jpg
Orchid Island, Taiwan -- Flower-shaped orange nudibranch egg ribbon on coral substrate.<br />
<br />
Nudibranchs lay their eggs in every size, color and shape imaginable from an oviduct located on the right side of their body. In some instances a  single ribbon can contain up to 25 million eggs!<br />
<br />
Most often the egg ribbon takes the shape of coils or spirals, but sometimes they appear as tangled masses of strings, chains of beads, or cylinders.<br />
<br />
The egg ribbon is usually laid counterclockwise, which allows the nudibranch to achieve a better spiral shape and also to anchor the egg mass with its foot.<br />
<br />
Some species produce eggs that are caustic or even toxic. These egg masses are usually brightly colored as a warning to potential predators.
