Adult Size: 20 – 40 mm

Reproduction: Hermaphroditic; mates reciprocally, with small, coiled egg ribbons laid in protected reef areas
Fun Fact: Phyllidiella striata is distinguished by its striking grey body covered in thin black stripes and small white tubercles, creating a bold, zebra-like pattern that’s a standout in the reef’s sponge-draped landscape.
This robust nudibranch’s pattern and texture make it a favorite among underwater photographers, adding a dramatic contrast to the reef’s vibrant tapestry.
