The Daily Post : Weathered

I haven’t tried the Daily Post in a number of years, but I was inspired by today’s theme: weathered. I wouldn’t be me if I didn’t put a zookeeper slant on it, though, would I?

Riverbanks Zoo has a herd of Galapagos Tortoises. We have Aldabra Tortoises at our zoo. These two species are a fascinating example of convergent evolution – animals that develop similar traits, but in different parts of the world. Galapagos Tortoises are found off the coast of Ecuador in South America, and Aldabs are found off the east coast of Africa in the Seychelles. They last shared a common ancestor about 20 million years ago. But they are so similar.

Here’s an Aldabra Giant Tortoise:

There are minor differences. Galapagos tortoises can get up to about 600lbs, depending on the subspecies, whereas Aldabs top out typically at 350. Though Big Al is a plus-sized model. He’s 525lbs. Galaps typically lack the little scale on their shell behind their neck, called a nuchal scute. Their shells vary, and some have really high arches at their necks to allow them to reach taller shrubs. And Galaps have a very round head by comparison to Aldabs, but you have to really know them to notice. My favorite difference is that Aldabs stretch out their necks to be scratched, while Galaps look straight up. ADORABLE!

The thing about both species is, they can live for, like, ever. Not really. Eventually they peter out, but they live a very, very long time. One animal died in 2006, and there were records on it going back 252 years, and it was a wild-caught animal. The oldest confirmed tortoise was 189 years old. That’s a lot of wear and tear.

Time takes its toll on all of us, tortoises included.

It’s like looking into the face of a dinosaur. Weathered.

Time, wind, and water wear us down. The scales on this Galapagos tortoise girl’s neck have worn smooth with time. Her shell, too, sports that lived-in look. She had a nice hole in her carapace (top shell) that is now a cozy home to a spider.

See the spider web? It was nice and fresh. The damage is purely cosmetic. Shells are tough!

She looks pretty good for her age, don’t you think? Just imagine, a century ago, she looked more like this:

This tortoise is under six months old, all shiny and pretty and new. There are plenty of growth rings in her shell, too. They are like trees. As they grow, they get new rings. The center of the ring is essentially dead shell, like our hair or fingernails, and the rings are fresh growth. This little baby is all bright-eyed and represents the future of her species.

And this girl? She’s bursting with history.

If this girl could talk…

  1. OH MY GOD! That is really really OLD! I am seriously impressed. How old is Big Al? Wait – I will go back and look – that hole in the shell is unsettling – a spider in there – it will tickle him – get it out! c

  2. Al’s still the cutest, but that little juvie is giving him a run for the money. (Love seeing that he gets the watermelon for enrichment and not just food.) Am I wrong in wanting to hug them all and give them neck and tail skritches?

    • Even their regular diet is given to them partially in the form of enrichment – I put it high places, or scatter it as forage for them to find. I even do that with my dog because meal times are so great, I want to stretch them out as long as possible!

      Al needs all the neck scratches.

  3. As someone who wanted to be a paleontologist as a child, you really had me at “looking at the face of a dinosaur”. I have now added scratching the neck of a tortoise to my bucket list
