Tumbes

At night, entire crates disappear from the Tumbes fish market. Giant footprints lead to the Tumbes River, and everyone is sure: Peru's only crocodile is the culprit.

However, Perusina discovers a flaw in the prints. This begins a wild chase across the market, the river, and through the waterways in northern Peru's green landscape.

The Case of the Fake Crocodile Tracks

A Tumbes crime story about vanished fish crates, wooden crocodile feet, and a massive suspect who cannot explain his innocence himself.

When Perusina, Perusino, and Franz walked through the Tumbes fish market early in the morning, something was amiss.

No one called out prices. No one laughed. Even the pelicans on the roofs waited unusually still.

Empty fish crates and giant crocodile tracks in the Tumbes market
Three crates of fish have disappeared. Only enormous tracks in the wet sand remain.

Doña Maribel stood in front of an empty stall, pointing at the ground. "Three crates of fish," she said. "Simply vanished. And this is the third night."

Huge prints lay in the wet sand. Four toes, wide claws, with a drag mark in between.

"A crocodile!" shouted a vendor. "The crocodile from the Tumbes River is robbing our market!"

Franz looked at the empty fish baskets. "A creature with taste."

The tracks look too perfect. Perusino's own print, however, ends up in a bucket.

Perusina knelt beside the tracks. "Strange."

"What?" asked Perusino.

"Every print looks exactly the same. Even that small crack on the left claw."

Perusino placed his foot next to it. The print was almost three times as large. In doing so, he stepped backward into a bucket of fish water.

Splash!

Franz wrinkled his nose. "Now we have bait."

The tracks led from the market to the river. Not a single track led back. Between two prints, Perusina discovered a sharp edge, as if someone had pressed a board into the sand.

Franz sniffed it. "Motor oil. Rope. Fish. And sweaty socks."

"A crocodile doesn't wear socks," said Perusina.

"Perhaps a polite one," Perusino suggested.

Perusina, Perusino and Franz observing the fish thieves with wooden paws at night
The nocturnal crocodiles walk on two legs and carry their own tracks.

The following night, they hid among empty crates. Perusina lay behind a stack of nets. Perusino crouched under a table. Franz sat in a fish basket, quietly complaining about the view.

Shortly after midnight, two men crept into the market. On their feet, they wore wide wooden plates shaped like crocodile paws. Behind them, they dragged a sack across the ground. The drag mark looked exactly like the trace of a heavy tail.

"There are our crocodiles," Perusina whispered.

The men grabbed two full crates of fish and ran to the river.

"Stop!" shouted Perusino, jumping out.

Fast chase through the Tumbes fish market
The chase begins with falling crates, flying fish, and a sliding fox.

One of the thieves knocked over a crate. Fish slid across the floor. Franz shot out of his basket, stepped on a mackerel, and slid belly-first across the market.

"On purpose!" he yelled as he whizzed by.

The thieves reached a motorboat. Seconds later, it sped across the Tumbes River.

Doña Maribel's brother untied his small fishing boat from the pier. "Get in!"

Boat chase of the three friends on the Tumbes River
The escape boat disappears among reeds and green waterways.

The chase led downstream. The thieves' boat vanished among reeds and mangrove branches. Its light kept appearing between the trees. Then it was gone.

"Which turn?" Perusino asked.

Franz lifted his nose. "Left! It smells of fish and bad socks there."

They turned. In front of them, mangrove roots swayed in the black water. Two eyes appeared between the leaves. Then a long, narrow snout emerged.

"Crocodile," Perusino whispered.

The real Tumbes crocodile leads the friends to the lost fish crate
Only eyes and nostrils protrude from the water. An important piece of evidence is clamped between its teeth.

Only eyes and nostrils protruded from the water. The rest of the body remained invisible.

The crocodile swam past them. A piece of rope was clamped between its teeth.

"That belongs to the fish crates," Perusina said.

They followed it.

Around the next bend, a broken crate lay in the water. Fish drifted among the roots. The crocodile had only followed their trail.

Further ahead, the thieves' engine sputtered. When they noticed the crocodile, they spun their boat around. In doing so, they ran aground on a shallow sandbank. The engine roared. The boat didn't move an inch.

The fake crocodile feet are discovered in the mangrove mud
The fake crocodile tracks become the undoing of their inventors.

The men jumped into knee-deep water, wanting to escape. But their wooden crocodile feet got stuck in the mud. First one stumbled, then the other. Finally, both were stuck, thrashing like two overturned beetles.

Shortly thereafter, the river rangers arrived. In the boat, they found the stolen fish crates, the drag rope, and four carved crocodile feet.

The next morning, the entire market knew that the Tumbes crocodile was innocent.

Doña Maribel offered the friends breakfast. Perusina had fruit, Perusino a large bread, and Franz a bowl of water.

"Water?" Franz asked, offended.

"You already smell enough like fish," Perusino said.

From the river, two eyes emerged from the water.

Franz carefully pushed his bowl towards Perusino.

"You need it more," he said.

Case closed: Not the Tumbes crocodile, but two fish thieves stole the crates. Their wooden crocodile feet were meant to lay false tracks and ultimately became their biggest mistake.

What's in this adventure?

The Tumbes crocodile belongs to the American crocodile species and is the only naturally occurring crocodile species in Peru. Its most important habitat in the country is in the far north.
When swimming, often only eyes and nostrils remain above water. An additional transparent eyelid protects the eyes underwater.
Near Puerto Pizarro, the Tuna Carranza Aquaculture Center works on the conservation and reproduction of endangered crocodiles.

Three clues from the friends

Perusina compares carefully

She recognizes that natural tracks never look perfectly identical and discovers the edge of the carved wooden paws.

Perusino starts the chase

He is the first to jump out of hiding and doesn't stop, even with fish water, market chaos, and a speeding boat ride.

Franz smells the difference

His nose finds motor oil, rope, and the trail of fish crates. Only the smell of socks he would have gladly seen disappear.

Your explorer task

Draw three real crocodile tracks that differ slightly from each other. Next to them, draw the same print of a wooden paw three times. Mark the repeated scratches and edges where Perusina might recognize the fake.

Questions about Tumbes

Did this story really happen?

No. The fish thieves and their wooden crocodile feet are fictional. However, Tumbes, the Tumbes River, and the Tumbes crocodile are real.

Is the Tumbes crocodile its own species?

It belongs to the American crocodile species with the scientific name Crocodylus acutus. In Peru, it is called the Tumbes crocodile because of its most important habitat.

Is it really the only crocodile in Peru?

Yes. The American crocodile is the only naturally occurring crocodile species in Peru. Its Peruvian occurrence is concentrated in the far north.

How can a crocodile see underwater?

It has a transparent additional eyelid. This nictitating membrane protects the eye and functions underwater similarly to diving goggles.

What do children learn in this adventure?

They learn to compare evidence, not to accuse animals prematurely, and to understand why endangered species and their habitats must be protected.
