Also known as Maiden's hair plant, this popular, stringy algae is often mistaken for hair algae and enters the aquarium trade on live rock and coral. It is toxic, making it inedible and capable of effecting coral growth, though microinvertebrates enjoy living within the algae such as amphipods and copepods.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. [1] Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and ...
The classification of corals has been discussed for millennia, owing to having similarities to both plants and animals. Aristotle's pupil Theophrastus described the red coral, korallion, in his book on stones, implying it was a mineral, but he described it as a deep-sea plant in his Enquiries on Plants, where he also mentions large stony plants that reveal bright flowers when under water in ...
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
The purple sea fan is found in the western Atlantic and Caribbean, with a range extending from Bermuda and Florida and the Gulf of Mexico to Curaçao.It grows near the shore in shallow water in areas with strong wave action and on deeper outer reefs with strong currents down to a depth of about 15 m (49 ft).
A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves.
Other notable invasive plant species include floating pennywort, [58] Curly leaved pondweed, [57] the fern ally Water fern [57] and Parrot's feather. [59] Many of these invasive plants have been sold as oxygenating plants for aquaria or decorative plants for garden ponds and have then been disposed of into the environment. [57]
The underwater farm is placed about 40 m (130 ft) away from Letizia Beach, found between the cliff of Capo Noli and Punta Vescovato, and between 32 and 40 ft (9.8 and 12.2 m) under the sea level. In Liguria the general depth of the sea varies from 6,500 feet (2,000 m) and 10,000 feet (3,000 m), but in the area of Noli the depth reaches a ...
