For our Halloween fun today, it’s a good time to look at wild animals that give us a slight chill. Wild animals have a rawness that is unpredictable and can indeed be spooky.

These are not even some of the very scariest animals (like a hyena) because I don’t want to give you nightmares.

We start with a fellow mammal, a Halloween specialty, the bat. This one is a spectacled flying fox. We came upon a colony in a forest in northern Queensland, Australia.

You can see in the photo below the bat looks bespectacled, for which it is named.

Some of the creatures here just look spooky because they’re different, but others really are spooky for how dangerous they can be.

Below is a male African buffalo. We were in Zambia, Africa and more than once our jeep came from behind tall grass and there one would be, glaring at us.

Took my breath away a few times.

His left eye is scarred and half-shut, no doubt the result of a fight. A typical male, like this one, weighs 1,650 pounds (750 kg).

This hippo, below, was scarred and surly. Some people may think hippos are kind of cute, but when you are near one in the wild, you immediately grasp the sobering presence they exude.

Hippos are fast–faster than they look.

Below are warthogs we came upon in Zambia; they had been digging for roots and tubers. Long, flat snouts, sharp tusks and soulless eyes. A strong-legged and very fast animal.

While on a safari walk, the guide told us to stay away from ground holes because the warthogs cleverly back into burrows, out of sight, and come charging out tusk first if they are threatened.

There are many intimidating African animals in the wild, but we’ll look at just two more, seen in Botswana.

The male lion, below. I think we all know to fear this formidable creature. They swagger confidently and have piercing golden eyes and when it’s the right time, they pounce and tear flash like the warriors they are.

This is a cobra we encountered. The snake’s hood (neck) is flared and its head is up, ready to strike.

Shimmery and golden in the African sun, but deadly.

Let’s hop on our witchy broomstick to head over to the western hemisphere, look at more spooky creatures.

Galapagos Islands. Far out in the Pacific Ocean about 600 miles (1,000 km) from the mainland, the wildlife has evolved in isolation, unaccustomed to humans.

These two wild iguana species, below, were not dangerous to be around, but just so incredibly unusual. Absolutely prehistoric looking.

The only living lizard that forages in the sea, marine iguanas are slow on land but graceful under water. We saw hundreds of them basking on rocks and even found a few in the water when we were snorkeling.

In 1835 Charles Darwin reported the Galapagos black lava rocks were frequented by these “most disgusting, clumsy lizards.” That seems a bit harsh–he probably found them on one of the days he was having stomach troubles.

Equally as curious-looking were the land iguanas. Here is a pair, below.

Peeling skin, crusty faces, long rat-like tails and gnarled claws.

Let’s head to Central America next. But yikes, this broomstick is so uncomfortable. Let’s switch to a magic carpet.

This American Crocodile, below, was churlishly staring at us as our little boat cruised by. Look at that mouth. Even when the chops are shut you know there’s pointy, sharp teeth lurking inside. How many teeth? About 65.

The array of spooky insects we have on this planet is immense. Many are very cool, but I’m taking it easy on you today. I’ve just got one for you, the assassin bug, below.

They’re called assassin bugs because they use an “assassination” method to hunt and kill. They ambush their prey, then grab them with their front legs, inject them with paralyzing saliva and then suck out the liquefied innards.

Heading north to America for the last two spooky creatures.

We were eating our sandwiches inside the car in a parking area when this big bison wandered very close to us, apparently attracted to the mud puddle. We could hear its steady, heavy breathing.

We were of course thrilled but a little nervous.

They’re faster than they look too, faster than most horses.

Lastly, my own backyard. We lived on an isolated mountain top and in the summer it was hot and dry.

This mature rattlesnake, below, hung out with us one summer.

We agreed not to bother each other, and it worked out. Why did we do that? Because the rattlesnake kept the rodent population under control.

Its head is in the center of the photo below, and it is looking at you. Rattles are on the right; there are 7 or 8 or 9?

It rattled at us a couple of times that summer, but we quickly got the message.

There’s something so gripping and powerful about wild animals. Add to that the dark superstitions of this holiday that go back centuries, and we have ourselves a spooky Halloween.

Happy Halloween!
