A new study has found that the free-living mushroom coral responds to specific types of light by “walking” towards it, suggesting remarkable adaptability in the marine species.. Not all corals ...
Corals are highly adapted to their local seasonal temperature and light conditions, influencing their physiology and calcification rates. [15] While increased temperature or light levels typically stimulate calcification up to a certain optimum, beyond which rates decline, the effects of temperature and light on the calcifying fluid chemistry ...
Corynactis californica is a brightly colored colonial anthozoan corallimorph.Unlike the Atlantic true sea anemone, Actinia fragacea, that bears the same common name, strawberry anemone, this species is a member of the order Corallimorpharia, and is the only member found on the west coast of North America.

Zooxanthellae require a mixture of white and blue light to thrive within the coral, depending on the coral type. [11] Some corals, like the orange cup coral, do not require light, and rely on the plankton or free-floating nutrients as sustenance. [12] Coral reefs protect the coastline from erosion and storm damage.
Scientists have warned about corals’ fate for years. In 2018, the Intergovernmental Panel on Climate Change estimated that 70% to 90% were at risk of “long-term degradation” if global ...
Reef Check is an international non-governmental organization dedicated to the conservation of two reef ecosystems: tropical coral reefs and Californian rocky reefs. The Foundation is headquartered in Los Angeles, California, United States, but uses data from volunteer scuba diver teams in over 80 countries, ranging from Australia, Japan, to even Germany.
Lighting: Several lighting options are available for the reef-keeper and are tailored to the types of coral kept. Canopy: The canopy houses the light fixtures and provides access to the tank for feeding and maintenance. Filtration and water movement: A variety of filtration and water movement strategies are employed in reef aquaria. Bulky ...
Porites is a genus of stony coral; they are small polyp stony (SPS) corals. (Also referred to as finger coral or hump coral) They are characterised by a finger-like morphology . Members of this genus have widely spaced calices , a well-developed wall reticulum and are bilaterally symmetrical .
