Posts Tagged ‘mutualism’

You may know from watching nature shows that there is something in the animal world called symbiosis or mutualism. What it means is that two unlikely creatures form alliances for their mutual benefit. I will offer a few examples with stunning photographs from Wikipedia and then my own humble example.

Perhaps the most well-known example of symbiosis in the animal world – only because there have been so many photographs circulated about it – is that of the clownfish and the anemone.

Clownfish-Nick Hobgood2

The charming little clownfish seems to be one of the only, if not the only, sea creature that is immune to the anemone’s sting. That works out perfectly. The clownfish has a place of safety to which he can swim when predators pursue, and in turn, brings dinner right to the anemone.

Then we have cleaner shrimp. These slender, delicate shrimp perform an important function for a variety of sea-dwellers from groupers to anemones to eels, as we see below.

Here a cleaner shrimp does a tidy-up on the mouth of a moray eel. The benefit to the eel is that of a good dental/oral cleaning as bacteria is removed from its mouth. For the shrimp, who is a scavenger, a meal on the go.

Not all examples of symbiosis are under water. For example, oxpeckers are birds that often co-habit with zebras, (and other large mammals), for mutual advantage. The oxpeckers eat lice and ticks from the zebras’ coats and help the zebras by screaming when predators are nearby. Crocodiles and plovers co-exist with the plovers popping right into the crocodile’s mouth. Once again, in exchange for a good dental cleaning, the croc allows the plover whatever morsels he can find.

And then we come to my personal example:

Pumpkin-Symbiosis2

A cat and a car. Perhaps the most mysterious and least understood, (to the average passerby), of symbiotic relationships, there are even tertiary benefits in this relationship – to me!

Pumpkin, my buddy from next door, likes to take his nap in the shade of my bumper. The hotter it gets, the deeper in the cool shade he lies. The benefit to Pumpkin is obvious, but what about the car?

Two stories came to my attention awhile back. My neighbor across the street found one day that his truck wouldn’t start. It was taken by flatbed to his mechanic who found that a goodly number of field mice had set up housekeeping in his engine and chewed through all the wires. So bad was it, that it couldn’t be repaired. It was either a new engine in the truck or a new truck. The neighbor across the street on his other side was driving to work when her car simply stopped running. She coasted to the side of the road, was taken by flatbed to her mechanic, who found that a goodly number of field mice had set up housekeeping in her engine and chewed through her wires as well. Luckily, her car could be repaired.

Getting my drift? So while I am always aghast to see the occasional mauled mouse that Pumpkin, (or his cohort Cloudy, my other buddy from next door), leaves lying about, I also know his presence is keeping my engine intact. Which means I get to drive knowing my wires are not chewed through, both cats get shade and bottomless bowls of food and water on my back porch, and we all get some cuddling and hanging-out time.

Beats eating ticks and lice or screaming at the approach of predators, eh?
