The truth behind the symbiotic relationship

The truth behind symbiotic relationships

I love playing with the idea of symbiotic relationships, however it was only after producing this cartoon that I discovered that this well known example of a symbiotic relationship may not actually be a match made in heaven, but somewhere in-between.

It’s the African oxpecker bird that feeds off the backs of hippos, zebras and elephants. People used to think it was the perfect symbiotic relationship (what’s called mutualism – a relationship where both species benefit), with the oxpecker snacking on the irritating ticks. However, on closer inspection, the reality is that the birds are actually sucking on the blood from the open wounds created by the ticks (…a possible parasitism relationship where one species nourishes itself to the disadvantage of the other?) Yes, the oxpecker eats a tick or two in the process, but perhaps that’s collateral damage or a refreshing palette cleanser. The oxpecker does however provide the animal with an inbuilt alarm system. It screeches loudly when started and might just give enough warning to its host that a predator is not far away. If the warning serves no benefit, then perhaps its a symbiotic commensalism relationship, where one species obtains food or shelter from the other without harm to its host.

So who is the winner here? Oxpecker or Rhino? Or is it win-win?

    The way I see it, the bird is a vampire, a blood sucking son of a bird. They are so cunning should a real cannibal comes along, it sounds the alarm. Yay, the rhino is alive. That saves the day. No?

    It did give me a chuckle when I saw it without reading the explanation. Thanks Mart,

    Unless I’m remembering wrong, I think vampire bats kind of do the same thing… will feast on an animal wound I mean. I guess if the rhino really had a problem with it, it could get rid of the bird easier than it could get rid of the ticks… so maybe the rhino is fine with whatever the arrangement is?

    I definitely think the hippo is getting the short stick there! Icky.
