Parrot
A Lionfish is any of several species of venomous marine fish in the genera Pterois, Parapterois, Brachypterois, Ebosia or Dendrochirus, of the family Scorpaenidae. The lionfish is also known as the Turkey Fish, Dragon Fish, Scorpion or Fire Fish.[1] They are notable for their extremely long and separated spines, and have a generally striped appearance, red, green, navy green, brown, orange, yellow, black, maroon, or white.
Parrotfish are named for their dentition; their numerous teeth are arranged in a tightly packed mosaic on the external surface of the jaw bones, forming a parrot-like beak which is used to rasp algae from coral and other rocky substrates (a process called bioerosion). Many species are also brightly coloured in shades of blue, green, red and yellow, but are not especially popular in aquaria.
Although they are considered to be herbivores, parrotfish eat a wide variety of organisms that live on coral reefs. Some species, for example Bolbometopon muricatum may include corals (polyps) in their diet. Their feeding activity is important for the production and distribution of coral sands in the reef biome and can prevent algae from choking coral. The teeth grow continuously, making it hard to curb overgrowth in the aquarium. Ingested during feeding, coral rock is ground up by the pharyngeal teeth. After they digest this it is excreted as sand thus at times creating small islands and the idyllic sandy beaches of the bahamas and caribbean.
Maximum sizes do not vary widely within the family, with the majority of species reaching 30 centimetres (12 in) to 40 centimetres (16 in) in length. However, a very few species, such as the the bumphead parrotfish (Bolbometopon muricatum), are much larger, up to 100 centimetres (39 in).
Their bodies are deep, with large, thick cycloid scales, large pectoral fins and homocercal tail fins. The pectorals are the parrotfish's primary means of locomotion, the tail only used when speed is required. Some parrotfish females can turn into male parrotfish.
The Princess Parrotfish (Scarus taeniopterus) is a tropical reef fish, typically 20 to 25 cm long, found in the Caribbean, South Florida, Bahamas, and Bermuda. Its behavior, similar to other Parrotfishes, is to swim about the reef and sandy patches during the day, at depths between 3 and 25 meters, scraping algae on which it feeds.
