Starry ray

The starry ray is the only ray species which can roll itself into a kind of ball. When in such a position, it isn't easy for large predator fish to catch them. Starry rays hunt crustaceans, worms and fish. They'll even eat dead animals if they happen to find one. The starry ray is the most common species of rays in the North Sea; however they are rare along the Dutch coast.

  • Rough egg capsules

    Egg capsules from starry rays together with those of the thornbacks are the most commonly found ray eggs on Dutch beaches. Starry ray egg capsules are rough, while thornback capsules are smooth. Sometimes, large amounts of these egg capsules wash ashore. Starry rays lay 6 to 40 eggs per year on the sea floor. When the eggs hatch, they young rays are 10 centimeters long.

  • Distribution of starry rays
