The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. . They live in a cleaning symbiosis with larger, often predatory, fish, grooming them and benefiting by consuming what they remove. "Client" fish congregate. This neither harms nor benefits the whales = (commensalism). Honey Guide Bird/ Wrasse fish feed on the parasites found on the black sea bass's body. The relationship between cleaner wrasse and reef fish has long been one of the textbook examples of mutualism, a partnership in which both individuals benefit. Kelp bass and a cleaner wrasse.

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.

Why do the pairs live together?

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. A strict hierarchy exists among the occupants of each anemone, which hosts only one dominant pair at any time. The female is the largest in this "family," followed by the male and the adolescents. A mature pair assure their continued dominance by chasing the juveniles, causing stress and reduced energy for food foraging.

The female occasionally reminds the male who's boss by nipping at his fins. James Prosek, National Geographic, January ] Many reef fish have the ability to change from one sex to another. Most, such as wrasses and parrotfish, change from female to male. But the clownfish is one of the few known to change from male to female: If a dominant female dies, the dominant male will become the dominant female, and the largest remaining juvenile will assume the role of dominant male.

No one has yet identified the hormones responsible for this sexual plasticity. Clownfish are now raised in fish farms in the Bahamas and other places. The trick to raising clownfish is to make sure they have an enough anemones in their tank. Combing through coffee table books on sea life, his eye landed on a photo of two fish peeking out of an anemone. There's almost nothing more appealing than these little fish that want to play peekaboo with you. Nemoa clownfish of the species Amphiprion perculaintroduced millions of children around the world to a wondrous tropical ecosystem: The clownfish and the anemonetheir relationship has captivated home aquarists since the s, when improvements in the shipping of fish and in tank design and filtration caused a boom.

But never before has a fish had a bigger boost than the clownfish in the wake of Finding Nemo unlike the notoriety of a very large mechanical killer with teeth. At first, fear spread through the aquarium industry that the story line would cause a backlash: Nemo is captured and held in a tank in a dentist's office, and his father spends the rest of the time trying to rescue him.

For years it has cost much less to catch and ship wild-caught clownfish than to raise the fish in captivity.

Breeding them in tanks presents certain challengesgetting the larvae to feed, for oneand it takes at least eight months to grow them to marketable size. But the economics of wild clownfish have been changing: Rising fuel costs have made shipping them more expensive, and populations have been declining.

Overharvesting and invasive collection methods, such as the use of cyanide to stun and capture fish, are destroying reefs and their inhabitants. In the Philippines and Indonesia, for instance, clownfish have been severely depleted.

What is the relationship between wrasse and bass

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. 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. 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.
