Question 1 of 8

While trying to catch a freshwater sawfish at night, what device does Jeremy Wade use to wake himself up in the event of a bite?

A bell
A live fish
A soda can
Nothing, he stays awake

... Just like any experienced fisherman, Jeremy Wade uses the resources immediately available to him in order to create a makeshift warning device when something bites his bait. In the case of the freshwater sawfish, Jeremy uses a soda can.


Question 2 of 8

True or False: The electric eel is, in fact, an eel.


... Surprise! The electric eel isn't actually an eel. It's a knifefish: an order of South American fish that have long bodies and swim using undulations of their elongated anal fin. All knifefish can produce electrical fields for navigation and communication. The electric eel is unique among them in that it can create a massive shock for attack and defense.


Question 3 of 8

When investigating an attack, the following clue would rule out the stingray as the culprit:

The attack happened in freshwater
There are no traces of blood
The attack happened in the tropics
There are piranha living in the same habitat

... The typically shy stingray attacks only when threatened. It does so by flipping up its barbed tail like a scorpion. Should the stingray score a hit, its stinger will pierce the victim's flesh, drawing blood. The barbs often break off from the stingray's tail and lodge in their victim.


Question 4 of 8

Which sense does the Japanese giant salamander rely on to navigate its environment?

None of the above

... The Japanese giant salamander has poor eyesight, hearing and sense of smell. It instead detects movement and vibrations in the surrounding water via a special sensory system called the lateral line. The salamander's flanks are lined with a line of sensory cells, called neuromasts, each of which is composed of a group of hair cells. These respond to vibrations in the water much like our ear cells respond to audio vibrations.


Question 5 of 8

Which line is the best choice for catching an electric eel?

Braided wire
Wire wrapped in waterproof plastic

... Some electric eels can produce an electric charge large enough to light up an entire house, so a nylon fishing line is the safest choice to avoid an unwanted shock! And although rope would be a safe choice as well, it's overkill for a fish that doesn't typically weigh more than 45 pounds.


Question 6 of 8

Longfin eel blood is poisonous. How much of it can be fatal to a person?

Only a few drops
Three teaspoons
One cup
Two cups

... This is some powerful blood! Just a splash on your lips or mouth can cause inflammation for days, and just a few teaspoons, if ingested, could kill you. As Jeremy inspects a dead longfin eel, he makes sure to thoroughly wash his hands to prevent any type of reaction.


Question 7 of 8

It's easier to catch a wolf fish during the dry season when the river isn't swollen. True or false?


... It's actually easier to catch a wolf fish during the wet season when it heads upstream and disperses into the flooded forest. As the water recedes, the wolf fish is forced to head back down to the main river.


Question 8 of 8

Which river monster is most likely to bite one's manhood off?

Freshwater sawfish
Japanese giant salamander
Wolf fish
Red-bellied pacu

... Two fishermen bled to death in separate incidents in June of 2001 along the Sepik River in northwestern Papua New Guinea after having their penises bitten off by red-bellied pacu fish. Closely related to the piranha, the red-bellied pacu follows urine streams in the water, swimming to their source. Their humanlike teeth are strong enough to break through seeds and nuts.
