Technically Incorrect offers a slightly twisted take on the tech that’s taken over our lives.

Crocs are more athletic than you might think.

Not too long ago, I wrote about a Russian fighter jet that performed a wondrous — and, to my mind, quite frightening — vertical takeoff.

This wasn’t a maneuver I would have readily associated with, say, a crocodile.

I understand that crocs, while appearing endearingly lazy, can be very swift across the ground if they happen to be annoyed or hungry.

I wasn’t aware that their tails could propel them in a perfectly vertical direction.

All hail, then, to National Geographic photographer Trevor Frost who posted this stunning act of dexterity on the part of a croc.

Lured by lunch or dinner — or, as crocs might term it, food — the croc seems to wiggle its tail in order to create propulsion. Then he goes straight up with quite a whoosh.

Frost explained that this was a saltwater crocodile. “Their tails propel them in the water like torpedoes from a submarine,” he said.

Perhaps this isn’t something you might see every day.

But should you be vacationing in the Everglades and think that you’re above the crocs and therefore safe, this video might show you that when a croc wants something, a croc’s going to do the most dynamic movements in order to get it.

You have been warned.
