Loss of clownfish leaves anemones exposed and vulnerable to predation. When reefs go bad, one of the first things to disappear is anemonesand their clownfish.

Besides spurring demand for clownfish, Finding Nemo helped fuel the explosion of websites and chat rooms devoted to raising reef fish in captivity. ORA breeds 13 clownfish species, as well as designer exotics such as the Picasso clown. Rado says he sells someclownfish a year"that's several hundred thousand that won't be taken from the wild. Many reefs are almost pristine and very healthy. They make up the largest marine fish family.
Ecological Relationships & Symbiosis
There are more than 2, different species worldwide. Among them is the crabeye goby which has fin markings called double eyespots that mimic huge eyes and are spaced at the same distance as the eyes of gobies that feed on fish that feed on gobies. Some inch-long translucent gobies live and feed in the mantles of giant clams.
Another kind leaps from tidal pool to tidal pool as the tide retreats.Odd Couple - Fish and Shrimp's symbiotic relationship
Somehow they know exactly where all the pools are and never miss. Apparently they make a mental map while tide is high and remember it when the tide is low. The orange-colored goby, fish found off the shores of Japan, changes sex. When a group of females are placed together the largest one turns into male, fertilizes the eggs and guards them. When a large male is placed with a small male the small male becomes a female.
Another species of gobies found near Japan live in burrows built by bulldozer shrimp. The two sea creatures have a symbiotic relationship.
The gobies alert the nearly blind shrimps to approaching dangers. The shrimps, in return build the burrows used by the gobies and keep them clean by bulldozing the sand in search of food.

One of most renowned experts on gobies is the Emperor Akihito of Japan. Akihito spends a great deal of time looking at specimens under a microscope in his palace laboratory. The Exyrias akihito is a species of goby named after the Emperor. A bottom feeder, it is 10 centimeters long a and has big bug eyes and orange speckles on its translucent body.
I have referenced his papers myself. I doubt there are more than a dozen scientists in the world who can match his expertise. They often start out as females and become males who vigorously defend territories.
As small females grow they become large enough to defend their own territories. When the become big enough they change sex, fight off male rivals and mate with females who come to visit.
If a male leaves the group, a female changes her behavior in minutes. Her color changes in a day. Within a week she produces sperm instead of eggs.
The dominant female controls sexual activity in her group. If she leaves and doesn't return her mate becomes the dominant female and a younger male become her mate. Wrasses are very good at changing color. One species quickly changes from ripples of green on an orange background to mostly orange when it suddenly opens it mouth to warn off a rival or stall a predator.
Male flasher wrasses flare out fins with bright blue markings that flash on and off. Describing the mating of flasher wrasses, Les Kaufman wrote in National Geographic: Job done, the male instantly went drab, and the consummated pair sped to get safety of the reef. They also eat dead skin and mucus. Some fish pull up to sections of reef inhabited with cleaning wrasses like cars pulling up to a car wash. The fish wait and line and when it is their turn the wrasse picks off parasites, fungus and pests.
The wrasses also provide free medical service, munching on tasty parasites which congregate around a given fish's open wounds. Wrasse cleaning station are often manned by a group of female wrasses and one male. When the male dies one of the females turns into a male. The wrasses clean squirrelfish, sea bass, butterflyfish, moray eels, parrot fish, scorpionfish, jacks, grouper and other predators much larger than themselves.
The wrasses even clean divers feet and climb into the gills and mouths of sharks and clean their teeth. The grooming of algae and other marine growths by wrasses is believed to help manta rays fend off life-threatening infections.
The wrasses set up cleaning stations at well defined areas. Fish signal they are ready to be cleaned by assuming a relaxed pose with their fins erect. The fish line up for their turn. One scientist observed fish get cleaned by a single wrasse at a single station in a six hour period. Cleaners wrasses swim in the mouths and clean many creatures that could easily consume them as a meal.
Barracuda have been observed swallowing wrasses after having their mouths cleaned. Studies have shown that the wrasses seem to distinguish hungry hosts from non-hungry ones by oscillating around the host to size it up. Around a well-fed trout the wrasse oscillated less often. The wrasse "dances in front of the new arrival with a bobbing motion. The grouper now hangs in the water, holding open its gill covers and mouth, often with its body tipped more vertically than horizontally, sometimes head-up.
The little wrasse swims in and fusses all over its client, trimming off pieces of dead skin, snipping away infestations of fungus, boldly venturing right into the huge jaws and coming out through the gaping gill covers. The squirrel fish appears to be swallowing him whole. But the four-inch daredevil backs out unscathed. Approaching each squirrelfish in turn, he nibbles at the flanks of one, at the gill covers of another.
When the visitors swim away, the slim blue-and-black fish remains by his post on the coral reef. When a predator comes around it dives into the burrow tail first. The fish lines its burrows with pebble walls and often get into fights with other jawfish over possession of pebbles.
Female jawfish place newly hatched young in their mouth to keep them protected for predators while allowing water to circulate and provide them with oxygen. When feeding the jawfish hides her young in a reef hole. Males also incubate eggs in their mouth. Some fasten an upside-down jellyfish to their back for camouflage and defense. Gardens of eels resembling two-foot-high sea grass can be found in some parts of the world, with the most well-known ones in the Red Sea. These eels bury their tails in the sand in holes that are tightly sealed with mucous.
Colonies of garden can have thousands of members and the eel's mucus lined holes are sometimes only a few inches apart. Discriminating among symbiotic relationships, including mutualism, commensalism, and parasitism 3 Symbiosis A close relationship between two species where at least one of the organisms receives some kind of benefit ex.
Mutualism Parasitism Commensalism 4 Mutualism Both organisms benefit, each species providing something needed by the other species. Termites have protozoans that live in their gut and digest wood cellulose Flowering plants and pollinating insects Plants provide food; insects cross-pollinate 5 Parasitism One Benefits, the other is HARMED Parasite relies on host for food Host is harmed, but usually not killed Endoparasites: The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds.
Both benefit from living together. Then the honey guide birds eat. Since the visual abilities of the 2 species are different, they can identify threats the other animal would not as readily see. The custom is of Scandinavian origin. In Norse mythology, Baldr was a god of vegetation.
To prevent this, she made every plant, animal, and inanimate object promise not to harm her son Baldr. The story goes that Frigga overlooked the mistletoe plant, so Loki was able to trick the blind god into killing her son Baldr, with a spear fashioned from mistletoe.
