Stony coral tissue loss disease (SCTLD) is a disease of corals that first appeared off the southeast coast of Florida in 2014. It originally was described as white plague disease . [ 1 ] By 2019 it had spread along the Florida Keys and had appeared elsewhere in the Caribbean Sea .
Stony corals are members of the class Anthozoa and like other members of the group, do not have a medusa stage in their life cycle. The individual animals are known as polyps and have a cylindrical body crowned by an oral disc surrounded by a ring of tentacles. The base of the polyp secretes the stony material from which the coral skeleton is ...

Pulley Ridge is a mesophotic coral reef system off the shores of the continental United States. [1] The reef rests on sunken barrier islands [2] and lies 100 miles west of the Tortugas Ecological Reserve and stretches north about 60 miles at depths ranging from 60 to 80 meters. [3]
This marine environment has been degraded in a variety of ways. Corals have been experiencing an increasing number of diseases. There is black-band disease which infects major coral reefs such as Montastraea annularis. [4] The most severe diseases are stony coral tissue loss disease, the white-band and white plague disease.

Several small crabs are obligate associates of corals, feeding on coral tissues but protecting the coral from attack by predators such as the crown-of-thorns starfish. One of these, Cymo melanodactylus , lives in association with Acropora cytherea but its low numbers (fewer than three per coral) mean that its host suffers little harm.
It includes all of the stony corals, most of which are colonial and reef-forming, as well as all sea anemones, and zoanthids, arranged within five extant orders. [2] The hexacorallia are distinguished from another class of Anthozoa, Octocorallia , in having six or fewer axes of symmetry in their body structure; the tentacles are simple and ...
