These animals create vast calcified structures, which serve as home to a variety of species, ranging from black-tipped sharks and eagle rays to octopi and cuttlefish. They are herbivores and keep the surfaces of coral reefs clean by feasting on the algae that can damage the reef. This problem may even be more pressing than the globe’s rising temperatures.

While coralsare sensitive to rising temperatures, they aren’t as sen… Write CSS OR LESS and hit save. Coral reefs are in decline in the U.S. and around the world. Unfortunately for corals (and the species who live in the reefs they construct), the ocean’s pH levels are plummeting, which is causing the corals to die off. One good example of an invasive species that is harming coral reefs is the lionfish – a beautiful species, which is popular in the pet trade. With its flare of long, venemous fins, the lionfish is an impressive (and beautiful) predator. Many times, this occurs when snorkelers and scuba divers swim too close to the reefs. This occurs because no local predators have evolved to prey upon them in these novel habitats. Hard corals, which have a stone-like skeleton, grow into reefs on the edges of tropical islands and continents. Found throughout the western Atlantic from Bermuda to Brazil, including the east coast of Florida, banded pipefish are associated with reef, coarse rock, and seagrass habitats. Butterflyfish, which form monogamous pairs, have a unique courtship ritual, swimming in circles up close to the surface of the ocean to release eggs and sperm into the water. Clown anemonefish are found in the warm tropical waters of the Pacific and Indian Oceans.

Each individual coral is a polyp, an animal, which hangs out with others to form these colonies. Many people are aware of the rising temperatures caused by climate change. This causes them to inadvertently break off pieces of coral, thereby resulting in the death of the affected part of the reef. Coral reefs are gigantic marine structures that form from the skeletons of organisms known as corals. Due to their lack of scales, mandarinfish are protected by their thick, smelly mucus coating. Many scientists now believe the very existence of coral reefs may be in jeopardy unless we intensify our efforts to protect them (Frieler et al. Blue tang are surgeonfish that inhabit the coral reefs of the Caribeean Sea. Often times, they are also free to live without fear of predation. Soft corals are individual animals (known as polyps) which move through the waters, and eventually settle. For example, they are often able to exploit resources more efficiently than they can in their native habitats. Clown anemonefish are bright orange fish with three white bands. The two have a symbiotic relationship: The stinging anemones protect the anemonefish, while the fish’s waste provides food for the anemone. Polyps are usually tiny, but they can range in size from a pinhead to 12 inches (30 cm) across. Hidden beneath the ocean waters, coral reefs teem with life.

When alive, corals are colonies of small animals embedded in calcium carbonate shells. Their beautiful shapes and colors are a magnet for divers, but they also provide an excellent home for thousands of marine creatures, including fish we love to eat.
