Crinoid facts: sea lilies and feather stars | Animal Fact Files

Crinoids are most well known for their impressive fossil forms, however, these plant-looking animals are still alive today. There are believed to be somewhere around 600 living, classified species of modern crinoids. Most crinoids of today are commonly known as feather stars and can be found in tropical waters and reef areas, however, the more ancient-looking types, commonly called sea lilies, live in much deeper waters. These sea lilies have stems connecting them to the ocean's bottom where feather stars have lost the stem and instead cling to surfaces using root-like feet. These animals are filter feeders.
