NO COMMON NAME (Oerstedia dorsalis): SPECIES ACCOUNT

Anoplans and enoplans live all over the world.


Most anoplans and enoplans live in the sea near shore— anoplans on soft bottoms and enoplans among algae. Algae (AL-jee) are plantlike growths that live in water and have no true roots, stems, or leaves. Some species live in deep, open water. A few species live in freshwater or on land. The land-dwelling species usually live on tropical islands in damp places under rocks and in rotting wood.


Anoplans eat worms, mollusks, crustaceans, and insect larvae. Mollusks (MAH-lusks) are animals with a soft, unsegmented body that may or may not have a shell. Crustaceans (krus-TAY-shuns) are water-dwelling animals that have jointed legs and a hard shell but no backbone. Larvae (LAR-vee) are animals in an early stage that change form before becoming adults.


The World Conservation Union (IUCN) lists two species of anoplans and enoplans as Vulnerable and one as Lower Risk/Near Threatened. Vulnerable means facing high risk of extinction in the wild. Low Risk/Near Threatened means at risk of becoming threatened with extinction in the future.
