Eider ducks primarily feed on marine invertebrates, such as mollusks and crustaceans, but they are also known to consume some types of echinoderms, including sea urchins. While sea urchins are not a primary food source for eider ducks, they may occasionally eat them if other preferred food items are scarce or available. The ducks use their strong bills to pry open the hard shells of shellfish, but sea urchins are more challenging to consume due to their spiny exterior. Overall, eider ducks may eat sea urchins, but it is not a common part of their diet.
