Mr. Nature: The Spiny Anteater

Echidna | San Diego Zoo Kids

Jambo! Mr. Nature here, and our safari today takes us to Australia and New Guinea in search of the spiny anteater, aka “echidna,” named for a creature in Greek mythology that was half-snake, half-woman.

These are really weird animals. For one thing, they and the duck-billed platypus are the only mammals that lay eggs. For another, they have the second-lowest body temperature among mammals, behind the platypus. And they’ve got a cloaca instead of separate reproductive and excretory organs. It’s sort of odd that they’re considered mammals at all. But they do have hair, and the babies, once hatched, are fed on milk from the mother’s body. Besides which, what else are we to call them?

As you might expect, they eat ants and termites; and aboriginal people sometimes eat them. No accounting for tastes. They look a lot like hedgehogs but aren’t related to them. They don’t look like platypuses, but those are their closest relatives.

God’s stuff–brought to you by a truly versatile Creator.

Is It Really a Mammal?

Hi, Mr. Nature here, with a critter a lot of folks have never heard of–the tenrec.

There are a bunch of different species of these little guys, living on Madagascar, Mauritius, and a few other out-of-the-way places in the Indian Ocean. And the thing about them is… are they really mammals?

We ask this because they maintain rather low body temperatures, and unlike all other mammals, but like birds and reptiles and amphibians, they have a cloaca instead of separate urine and genital tracts. That means one little hole for everything, as you’d find on a lizard or a canary. But at least they don’t lay eggs like the platypus or the spiny anteater (echidna).

God’s stuff is very complicated. We’ve been studying it for centuries and are still nowhere near to understanding all of it. We want all our living things sorted into nice, neat categories, and along comes some animal like the tenrec and muddies the waters. I mean, really, what’s a mammal doing with a cloaca?

King Solomon thought one could acquire wisdom by studying the intricacies and mysteries of nature. I’m sure he was right.
