10 most difficult fish riddlesFish quiz
Which fish is hunting on land?
African sharptooth catfish
Channallabes is a genus of airbreathing catfishes found in Africa. It grows up to about 33 centimeters. He lives in the muddy swamps of Congo and Angola. The main component of the diet of this species are land beetles living on land. Scientists hope that the discovery of this fish will allow us to understand the evolution of sea fish to terrestrial animals in the Devonian period. Their hunting method is probably similar to the methods of early vertebrates.
Which sea animal captures have grown significally since 1970?
In the 1990s several cod stocks collapsed due to overfishing. With the large predatory fish removed, their prey have undergone population explosions, and the capture of lobster has tripled since 1970.
What's the name of this type of fishing lures?
Surface lures are also known as top water lures, poppers and stickbaits. They float and look like fish prey that is on top of the water. They can make a popping, burbling, or even a buzzing sound. It takes a long time to learn how to use this lure effectively
Which dangerous fish breathes atmospheric air?
Electric eel lives in muddy floodplains of Orinoco basin. It is well adapted to this low-oxygen environment: it can breathe atmospheric air using a vascularized respiratory organ in its oral cavity. In fact, electric eels must rise to the surface every 10 minutes and inhale, otherwise they die not having enough oxygen from the gill.
What extinct animal did this skull belong to?
to golden toad
to armoured fish
Dunkleosteus is an extinct genus of arthrodire placoderm fish that existed during the Late Devonian period, about 358–382 million years ago. Some of which are among the largest placoderms to have ever lived. The largest species, D. terrelli grew up to 6 m (19.7 ft) long and 1 t (1.1 short tons) in weight. Numerous fossils of the various species have been found in North America, Poland, and Morocco.

Beluga (Huso huso)
Arapaima (Arapaima gigas)
Pangaz (Pangasianodon gigas)
Chinese Paddlefish (Psephurus gladius)
The arapaima, pirarucu, or paiche are any large species of bonytongue in the genus Arapaima native to the Amazon and Essequibo basins of South America. Genus Arapaima is the type genus of the family Arapaimidae. They are among the world's largest freshwater fish, reaching as much as 3 m (9.8 ft).
What fish is that?
The garfish is found in brackish and marine waters of the Atlantic Ocean and the Mediterranean, Caribbean, Black, and Baltic Seas. It is a long and slender fish with a laterally compressed body. They have unusual green bones (due to the presence of biliverdin) which discourages many people from eating them, but the green colour is harmless.
How does the frogfishes hunt?
uses a camouflage
As all frogfishes, A. hispidus is a voracious carnivore which will devour all right-sized prey that pass within reach, usually other fish, but sometimes even its own kind. It can swallow prey its own size. Frogfish are skilled hunters and some species are capable of blending into local environments such as coral reefs. A frogfish can camouflage itself so well that prey fish will swim close by without seeing the predator lurking before them. Then, before the prey knows it, he's eaten in about 6 milliseconds!
What fish is that?
green neon tetra
The neon tetra is native to blackwater and clearwater streams in the Orinoco and Amazon basin of South America. Its bright colouring makes the fish visible to conspecifics in the dark blackwater streams, and is also the main reason for its popularity among tropical fish hobbyists. It is often confused with the cardinal tetra, but its red coloration extends only about halfway to the nose, and its blue stripe is a less vibrant blue.
