The depths of the ocean are pitch black, how do the fish find food?

Some fish rely on light to attract some food, some fish rely on sound waves to lock on to some food, and each fish has its own unique method.

These fish use their skills and their own sensor system to find food, so they can distinguish between food and predators.

Some fish swim to shallow waters to hunt, some hunt by smell, and some have very sensitive ears and listen to sounds to hunt.

Summary. Based on your question, make the following answers:

What the little black fish saw was.

Jellyfish, large lobsters, strange fish, seaweeds, moray eels, small red fish.

Sentiment. In the past two days, my mother and I watched "Little Black Fish" together. I love this little black fish because it's very good at finding a way.

It was super clever to organize the little red fish into super big fish and scare away all the other big fish in the sea! My favorite thing is to see the last picture: the little black fish as eyes for the red fish.

It's so smart and cute! I also want to be like a little black fish, and find a way to solve problems when I encounter them!

What are the things that the little black fish sees in the depths of the sea?

There is no light in the deep sea, so how do fish find food?

In addition to being able to emit light on their own, deep-sea fish have a very sensitive sense of smell and touch, the main food in the deep sea is the carcass of food in the upper ocean, which is one of the main deep-sea plants.

The second is their sense of hearing, which is much more efficient in the deep sea than in the air, and any animal in the water can feel the waves if they want to move. Good hearing not only helps them maintain their balance, but also helps them feel the fluctuating effects of sounds and water waves from different organisms. Relying on these, coupled with your body's sensitive sense of touch, you can feel whether there is prey around you according to the change in water pressure.

So in the deep sea, animals don't necessarily rely on light to determine the location of their prey, but can also capture them through their senses of smell, hearing and touch.

The physiological structure of fish is different from that of humans, and their special physique can be seen.

I think that even creatures that are able to adapt to that environment without light have their own unique ways of obtaining food. For example, they can feel the fluctuations of the current to find prey. It can also be swallowed directly into the seawater to prey on plankton or zooplankton in the water.

Most of the fish in the deep sea rely on their sense of smell to find food, and their vision is only an aid, and they need to eat less food.
