All manner of baby-transport equipment is available to us humans, from strollers to backpacks to slings. Animals are not only a lot more “equipment-challenged” when it comes to moving their babies around, but most don’t have opposable thumbs or even hands to make the job a little easier.

This is where mouths come in handy. We’ve all seen a house cat carry its baby in its mouth by the scruff of the neck–but did you know that in addition to all the felines, pandas and other bears move their young that way, too? Crocodiles, on the other hand, just open up their mouths and let all their babies crawl inside! The young crocs’ view of the world must be interesting through all of those pointed teeth.

Scorpions and primates find it easier to carry their little ones on their backs. (You can bet those babies learn to hang on real fast.) And marsupials, of course, may have it easiest of all with those built-in pouches–or do they? The long feet on an active kangaroo joey don’t look like they’d be very comfortable for Mom.

Baby elephants don’t get a free ride anywhere–they’re too big. And many animals, such as lizards, don’t have parents around to help out at all. But however animal babies get around, they likely won’t be traveling that way for long, because they won’t be babies for long.
