Time to Start Looking Up: Crocodiles Can Climb Trees

Time to Start Looking Up: Crocodiles Can Climb Trees

If I were being attacked by a crocodile, I’d high tail it for high ground, preferably in the form of a nice, sturdy tree to climb up. With their stocky, solid bodies, crocodiles don’t look like they’re adapted for tree-climbing, and I figure I’d be pretty safe. As it turns out, though, I might be making a very poor life choice: a new study shows that crocodiles, despite all odds, can and do climb trees. Frequently. So I wouldn’t be enjoying the safety of my arboreal perch for long.

The researchers studied crocodiles in Australia, North America, and Africa, to get a range of crocodilian populations and behaviors. What they found was that in areas where there’s limited ground for basking, the animals will climb trees to access sun, and can in fact clamber all the way up to the crowns of trees to access some rays. Crocodiles, it would appear, take sunbathing even more seriously than supermodels.

However, their basking habits are bad news for hominids. People in regions where crocodiles are common are accustomed to keeping a lookout at ground level, and to being especially careful around sunny patches of ground and water. They aren’t, however, used to looking up for potential predators. A person walking through crocodile territory might be perceived as a threat — or a snack — and could be beset from above, which aside from being most unpleasant would be entirely unexpected. That means that people need to be warned about the potential dangers of crocodiles and the importance of looking everywhere for them, especially in their known territories.

Trees provide a great vantage point for crocodiles, allowing them to keep an eye out for potential rivals, animals stepping into their territory, and, of course, prey. Since many animals, not just humans, aren’t accustomed to looking for for potential predators, trees also provide an ideal camouflage spot for an ambush. A waiting crocodile can catch some rays while waiting for dinner to stroll by and drop straight onto whatever it’s hunting; the height combined with the heft of the crocodile would create quite a punch.

This study shows that crocodiles are extremely agile, something researchers already knew, but appreciated having confirmation on. In observations, researchers saw crocodiles approaching and resolving tree-climbing problems with remarkable physical and mental agility. They point out that given the bone structure of the crocodile, there’s nothing to suggest that the animals could climb trees; they don’t appear to have the physical adaptations needed. These nature-defying animals are a warning sign to people studying physical evidence of long-gone species in the form of fossils and skeletal remains: it’s possible that people may be making incorrect assumptions on the basis of found fossils, without living animals to observe.

Now that we know crocodiles are such avid climbers, walkers and other visitors to crocodile territory will have to be more careful, especially in shaded areas where the animals would have to climb up to access light for sunbathing. It’s important to keep an eye upward as well as towards the ground to scan for anything that might be lurking above.

Even the much maligned crocodile is capable of intelligence, emotions and friendship. (and they also experience sadness and stress) Just watch Steve Irwin's series, or videos of those who have tamed crocodiles. On Animal Planet Steve Irwin is rescuing and caring for crocs. Cut to a series about "Swamp People" moronic southern welfare collecting rejects who shoot crocs in the head. That lowlife gang and the equally insane US TV producers who broadcast environmental destruction and wildlife slaughter so they can make a buck from ratings should be jailed for what they've done.

Just watch Steve Irwin's series, and videos from those that have tamed Crocs for evidence that even the maligned crocodiles and alligators can show intelligence, emotion, compassion and friendship. There's a show on Animal Planet about Steve Irwin rescuing and caring about Crocs. Cut to an animal murder show about "Swamp people" (southern ignorant redneck rejects) boasting and shooting alligators in the head. One alligator is a million times more valuable than one of those Swamp Rednecks, or the lowlife US television producer who tries to attract ratings with sadism and blood.

I'd like to see it - I think it would be quite cute.

If crocodiles can climb trees, it would be really fun to see how they manage to wrap around a tree and clamber atop to snooze in the sun, but all from a very safe distance of course :) don't want it to start thinking of snacks while sun-bathing :) :)

Actually I am not to surprised about this information. Crocs are smart and powerful.

From the only two pictures presented. It appears to me that they are not actually climbing the trees. But walking up a downed tree or semi-downed tree. It's not like they're climbing a straight up and down tree. None the less, crocodiles are awesome creatures.

Scary!

Great, now every possible politician from N.Am to AU will want a crocodilian cull...

Seriously though, when has there ever been a report of someone being attacked by a crocodile from a tree? I think you need to watch your wording or you'll instill a panic that will threaten the life of these awesome creatures.

Furthermore, what animal isn't accustom to looking up for predators? Are you aware of the avian family of raptors? Maybe you need a lesson on snakes, primates, or invertebrates?

Regardless, thank you for the great information, this article was very informative.
