Coral reefs comprise less than o.1 per cent of the ocean’s total area. But they’re vitally important both to ecosystems and to people who depend on them. “One in every four species of fish live on a coral reef, there are over a million species that live ...
Some areas were hit particularly hard, like the Great Barrier Reef in Australia(澳大利亚大堡礁), one of the natural wonders of the world, where hundreds of miles of coral were bleached.Coral reefs are important to us, but they are in danger. What can we do to protect coral reefs? Write ...
“On the Great Barrier Reef and throughout the rest of the world, corals live in a symbiotic relationship with algae. Corals give algae shelter, and the photosynthetic algae give corals food (not to mention their bright colors). But when ocean waters get too hot for too long a time, cora...
Virtually all reef-dwelling corals have a symbiotic (mutually beneficial) relationship with algae called zooxanthellae. The plant-like algae live inside the coral polyps and perform photosynthesis, producing food which is shared with the coral. In exchange the coral provides the algae with protection ...
Another factor is over-fishing. When too many fish are taken out of a system the balance is disturbed. Many of these fish eat algae and control the abundance of algae on the reef. When the fish is removed, the fast-growing algae can take over. Destructive fishing methods such as cyanide...
Taste attractiveness was determined by offering agar pellets flavoured with extracts of comatulids and their symbionts for four coral reef fish species. Five species of symbiont were highly palatable, and one was indifferent to the taste. Almost all comatulids were distasteful, while their aversive...
Reefs also act as nurseries for large fish species, keeping them safe until they are large enough to strike out into the deeper ocean. Coral Reefs are important to the development of new medicines. Coral Reef plants & animals are important sources of new medicines being developed to treat ...
Mutualism is a type of symbiotic relationship in which two organisms live in close proximity and both benefit from the relationship. In this post, we're going over the definition of mutualism and some types of mutualism examples in the ocean.
It has been estimated that reef fisheries yield 10% of the world’s fish catch and 25% of the fish catch in developing countries (Kathiresan and Khan, 2013). Reef structures are deposits of particulate carbon, and calcium carbonate as a sink, and thus have great possibility to influence ...
