Hadromerida is an order of sea sponges belonging to the class Demospongiae.
Doriopsilla albopunctata is a species of dorid nudibranch, a colourful sea slug, a shell-less marine gastropod mollusk in the family Dendrodorididae.
Doriprismatica sedna is a species of colorful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.
Modiolus modiolus, common name northern horsemussel, is a species of marine bivalve mollusk in the family Mytilidae.
Clionaidae is a family of demosponges which are found worldwide. This family is known for parasitically boring holes in calcareous material such as mollusc shells and corals, using both chemical and mechanical processes.
Dragmacidon lunaecharta, common name red ball sponge or red boring sponge, is a species of demosponge found through the western Atlantic Ocean. It feeds on plankton. These sponges do not attach themselves to rocks or the sea floor but drift in water currents. Its main predators are seaslugs. It has been kept in home aquariums.
Serpula vermicularis, known by common names including the calcareous tubeworm, fan worm, plume worm or red tube worm, is a species of segmented marine polychaete worm in the family Serpulidae. It is the type species of the genus Serpula and was first described by Linnaeus in 1767. It lives in a tube into which it can retract.
Cliona patera, commonly called Neptune's cup sponge, is a species of demosponge in the family Clionaidae.
Crassadoma is a genus of rock scallops, marine bivalve molluscs in the family Pectinidae. It is monotypic, the only species being Crassadoma gigantea, the rock scallop, giant rock scallop or purple-hinge rock scallop. Although the small juveniles are free-swimming, they soon become sessile, and are cemented to the substrate. These scallops occur in the eastern Pacific Ocean.
Umimayanthus parasiticus, commonly known as the sponge zoanthid, is a species of coral in the order Zoantharia which grows symbiotically on several species of sponge. It is found in shallow waters in the Caribbean Sea and the Gulf of Mexico.
Cliona delitrix is a species of burrowing demosponge belonging to the family Clionaidae. It is found in shallow water in the Caribbean Sea and the Gulf of Mexico.
Cliona viridis, commonly called the green boring sponge, is a species of demosponge in the family Clionaidae. Its form varies according to the nature of the surface on which it grows. In limestone and other calcareous substrates it excavates channels and chambers while on other types of rock it encrusts the surface or forms massive structures. It is native to the eastern Atlantic, the Mediterranean Sea and the Indo-Pacific Ocean.
Oulophyllia crispa, sometimes called the intermediate valley coral, is a species of stony coral in the family Merulinidae. It is native to the tropical western and central Indo-Pacific region. Although this coral has a wide range, it is generally uncommon and seems to be decreasing in abundance, and the International Union for Conservation of Nature has rated its conservation status as being "near threatened".
Cliona orientalis is a species of demosponge in the family Clionaidae. It occurs in the Indo-Pacific region and is a bioeroding species, with various specialisations for living on and inside calcareous substrates such as massive corals and molluscs.
Goniopora tenuidens is a species of colonial stony coral in the family Poritidae. It occurs in shallow water in the tropical Indo-Pacific region. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Dipsastraea pallida is a species of colonial stony coral in the family Merulinidae. It is found in tropical waters of the Indian and Pacific Oceans. This is a common species of coral with a widespread distribution, and the main threat it faces is from the destruction of its coral reef habitats. It is rated as a "least-concern species" by the International Union for Conservation of Nature. This species was first described in 1846 as Favia pallida by the American zoologist James Dwight Dana; it was later transferred to the genus Dipsastraea, but some authorities continue to use the original name.
