Erronea cylindrica is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries. [1]
The shells reach 15–47 millimetres (0.59–1.85 in) of length. These cowries have a surface smooth and shiny. They are cylindrical, their basic coloration is pale brown or greenish, with irregular dark brown patches on the dorsum. The extremities are brown too. The lateral margins and the flat base are white.
They are living in warm tropical and subtropical waters, from intertidal zone to the deep reef, in coral reefs or sandy surfaces. Often they can be encountered in the low intertidal zone near the line of reef. As they fear light, during the day they are usually hidden beneath the reef rocks and coral caves. At dawn or dusk they feed, mainly on sponges, algae, small crustaceans and polyps of corals. Mantle and foot are well developed, with external antennae.
This species is found throughout the tropical Western and Central Pacific Ocean and in the Indian Ocean, in seas along Thailand, NW Australia, Philippines, New Zealand, New Caledonia, Guam and Madagascar.
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
Marine ecosystems are the largest of Earth's aquatic ecosystems and exist in waters that have a high salt content. These systems contrast with freshwater ecosystems, which have a lower salt content. Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply and 90% of habitable space on Earth. Seawater has an average salinity of 35 parts per thousand of water. Actual salinity varies among different marine ecosystems. Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides. Other near-shore (neritic) zones can include mudflats, seagrass meadows, mangroves, rocky intertidal systems, salt marshes, coral reefs, lagoons. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.

Porites cylindrica, commonly known as hump coral, is a stony coral belonging to the subclass Hexacorallia in the class Anthozoa. Hexacorallia differ from other subclasses in that they have 6 or fewer axes of symmetry. Members of this class possess colonial polyps which can be reef-building, secreting a calcium carbonate skeleton. They are dominant in both inshore reefs and midshelf reefs.
