5 amazing symbiotic animal relationships you didn't know about | From the Grapevine
You scratch my back, and I'll scratch yours, say plenty of animals. Different animal species help each other out all the time in the wild, using. Symbiotic relationships are an important component of life in the ocean. In such relationships, plants or animals of different species may be dependent on one. Some have lifelong relationships with other organisms, called symbiotic relationships. There are three different types of symbiotic relationships: mutualism.
TL;DR Too Long; Didn't Read Biologists and ecologists define a symbiotic relationship as an intimate interaction between two or more species, which may or may not be beneficial to either.
Biology's Classification System The system for classifying species — taxonomy — uses different classification levels to sort where an organism fits in the biological scheme of things, as well as helping researchers to understand the relationships between organisms and across classifications. At the top of biological's organizational chart sit the broadest categories — the domains archaea, bacteria and eukarya — followed by kingdoms, phylum, class, order, family, genus and species at the tip of an upside-down triangle.
The archaea and bacteria domains include only single-celled organisms, while the eukarya kingdom includes protists, fungi, plant and animals.

What Is a Symbiotic Relationship? | Sciencing
The honey bee and the flower represent this kind of relationship. The bee collects nectar from the flower using a long, straw-like proboscis to suck the sweet fluid into a separate sac called a nectar or honey sac for later use in the colony as food. While the bee moves about the flower, pollen collects on its furry legs and body.
When the bee leaves the flower to land on the next one, the pollen falls or rubs off onto the next flower, resulting in pollination. The flower helps the bee by giving it nectar, and the bee helps pollinate the flower by moving pollen from flower to flower.
A Mutualistic Relationship The relationship between ants and aphids, for example is a mutualistic one defined as defensive symbiosis. The ant acts like shepherds over the aphids.

Aphids provide honeydew for the ants, and the ants herd the aphids into their shelter at night for protection against predators, escorting them back outside in the morning. Some ant species are even known to take aphid eggs into the nest's storage chambers during the cold winter months. Often called ant cattle, sometimes ants remove the wings from aphids to keep them from flying away. The ants may also release chemicals that cause the aphids to become more docile.
One Organism Cannot Survive Without the Other Another type of mutualistic relationship — obligate mutualism — exists when each individual species cannot survive without the other. An example of this occurs between termites and their intestinal flagellate symbionts — prokaryotic organisms with whip-like flagella or appendages that help them move.
The organisms within the termite help break down the dense sugars in wood so that the termite can digest it. But termites also have other symbionts in their innards that work in cooperation with each other and the termite.

Without this relationship, termites and their inner guests would not survive. Not Obligatory, but Beneficial to Both The clown fish and the anemone represent protocooperation symbiosis, a relationship that benefits both, but unlike the termite's and its symbionts, both can survive independently of the other. The fish has a home within the fat, wavy arms of the anemone that protects the fish from predators; the fish also protects the anemone from its predators and sometimes even brings it food.
Cells Living in Other Cells When one organism lives inside the tissue or cells of another, biologists define that as endosymbiosis.
For the most part, these relationships are the norm for many unicellular entities. For example, a unicellular eukaryotic a cell with an encased nucleus inside it organism Paramecium bursaria serves as a host to eukaryotic Chlorella algae cells.10 Mutualism Examples
The alga produces energy via the photosynthesis process, and the paramecium benefits as it receives some of that energy or food. Additionally, the algae reside inside a protected, mobile home — the body of the paramecium. Organisms That Live on the Surface of Another Another kind of mutualistic symbiosis involves one organism living on the skin or surface of another in a mutually beneficial relationship.
Leaf cutter ants have a special symbiont, a type of unicellular bacteria that lives on their skin.

Leaf cutter ants bring the cut foliage back to the colony where they inject it with a special type of fungus. The fungus serves as a food source for the colony, which the bacteria protect from other invading fungi species. Transport Hosts and Food Sources A phoresy symbiotic relationship occurs when one organism lives on or near the body of another, but not as a parasite, and performs a beneficial service to the host and itself. A species of marine life, the remora fish, attach themselves to the bodies of whales, manta rays, sharks and turtles and even ships via sucking discs atop their heads.
The remora, also called shark suckers, don't harm the host nor take anything from it other than eating the parasitic sea creatures that infest it. Remora fish also use the disc to hitchhike a ride from the host. Oxpecker birds are common sites atop the backs of rhinoceros where they eat the parasites and ticks living there. In a parasitic relationshipthe parasite benefits while the host is harmed.
Parasitism is an extremely successful mode of life; as many as half of all animals have at least one parasitic phase in their life cycles, and it is also frequent in plants and fungi. Moreover, almost all free-living animal species are hosts to parasites, often of more than one species. Mimicry Mimicry is a form of symbiosis in which a species adopts distinct characteristics of another species to alter its relationship dynamic with the species being mimicked, to its own advantage.
Batesian mimicry is an exploitative three-party interaction where one species, the mimic, has evolved to mimic another, the model, to deceive a third, the dupe. In terms of signalling theorythe mimic and model have evolved to send a signal; the dupe has evolved to receive it from the model.
This is to the advantage of the mimic but to the detriment of both the model, whose protective signals are effectively weakened, and of the dupe, which is deprived of an edible prey. For example, a wasp is a strongly-defended model, which signals with its conspicuous black and yellow coloration that it is an unprofitable prey to predators such as birds which hunt by sight; many hoverflies are Batesian mimics of wasps, and any bird that avoids these hoverflies is a dupe.
Amensalism is an asymmetric interaction where one species is harmed or killed by the other, and one is unaffected by the other. Competition is where a larger or stronger organism deprives a smaller or weaker one from a resource.
Antagonism occurs when one organism is damaged or killed by another through a chemical secretion. An example of competition is a sapling growing under the shadow of a mature tree.
