Okenia zoobotryon is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae.

Okenia zoobotryon is found in the temperate and warm waters of the western Atlantic Ocean and Caribbean Sea.

Occasionally the egg masses and adults are found on the bryozoan Scrupocellaria regularis and the red alga Gracilaria sp.

The eggs are enclosed in capsules and hatch after about five days, developing into veliger larvae that soon begin to feed on microalgae and are planktonic.

They settle in about eight days, being attracted to Amathia verticillata by chemical cues, and undergo metamorphosis into juveniles within twenty-four hours of settlement.
