Under special ...Crinoids are known as sea lilies because they live on a stem and have a flower-like body. They are analogous to starfish with a stem.After their near-extinction around the end of the Permian, crinoids recovered during the Triassic and re-occupied almost all ecological niches they had held in Palaeozoic times. Triassic crinoids comprise 33 genera in 12 well-defined families and 5 orders of the subclass Articulata; the systematic position of 4 additional families is unknown. The highest diversity was before the Mid Carnian ...Sea urchin in natural habitat. Sea urchins feed mainly on algae, so they are primarily herbivores, but can feed on sea cucumbers and a wide range of invertebrates, such as mussels, polychaetes, sponges, brittle stars, and crinoids, making them omnivores, consumers at a range of trophic levels.

Crinoids were relative skyscrapers in the community, sometimes towering up to two meters (6.5 feet). Lacy bryozoans occupied a lower level. Below them, huge numbers of brachiopods monopolized the muddy bottom. Sharks cruised above these crinoid forests, while smaller bony fishes weaved among the crinoid stalks.Paedomorphosis in crinoids is linked with shifts in life history as an adaptive response to rapidly fluctuating environmental conditions and habitat disturbance on a global scale associated with ...…
