Arothron meleagris, commonly known as the Guineafowl puffer or golden puffer, is a pufferfish from the Indo-Pacific, and Eastern Pacific. It is occasionally harvested for the aquarium trade. It reaches 50 cm in length. Guineafowl puffers have heavy rounded bodies that are uniformly black with numerous small white spots (black puffer or botete negro), bright yellow spots (golden puffer or botete dorado) or a mixture of the two morphologies with bright yellow spots and black patches.
They have large blunt heads with short snouts and are equipped with a set of massive teeth. They have small and similarly shaped anal and dorsal fins that are well back on their body. Their caudal fin base is long and deep and their caudal fin is rounded. Their body is covered with small denticles that resemble coarse sandpaper. When this fish is scared or frightened, they inflate and make. pesce palla faraona
Tetraodontidae is a family widespread in most tropical coral reefs. The coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa the animal phylum Cnidaria, which includes sea anemones and jellyfish.
Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. pesce palla faraona
Sometimes called rainforests of the sea, shallow coral reefs form some of Earth’s most diverse ecosystems. They occupy less than 0.1% of the world’s ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms,echinoderms, sponges, tunicates and other cnidarians. Coral reefs flourish in ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas.
