cnidarians first paralize their prey with stinging cells on their tenticles then they slowly move the food up into the bell to digest . They have no destinct mouth or anus so the food goes in and out around the same place .
Common relatives of crinoids include sea urchins, starfish, and sea cucumbers. These marine animals are all part of the phylum Echinodermata and share similar characteristics such as a spiny or calcareous endoskeleton and radial symmetry.

No, you are supposed to feed ducks out of your hands.
Yes, some species of crinoids can live in cold water environments. They are often found in deep-sea areas with colder temperatures, where they can feed on particles in the water column using their filtering arms. These deep-sea crinoids have adaptations to survive in the low temperatures and high pressures of their habitat.
The scientific name for the Crinoids is (class)Crinoidea.

No, they don't. Photosynthesis occurs in the chlorophyll of plants.. Crinoids are animals; do be specific, they are enchinoderms. They are closely related to starfish. Hope this helped!
The Age of Crinoids
it occurs in the precambrian period.
Sea urchins scrape algae from rocks. Crinoids are filer feeders. Holothurians, sand dollars, and ophiuroids often feed on detritus. Some are predators, like the starfish who preys on clams and oysters. See related links

Your use of the word "introduced" suggests that they were added to a specific habitat somewhere. The question cannot be answered without knowing which habitat they were supposed to be introduced to. Crinoids have been around for about 350 million years.
