Fish have gills, slippery scales, and lay eggs. They can live in high mountain streams, rivers, lakes, and all the way down to the bottom of the ocean. Fish can be plant eaters, meat eaters, or a mix of these two. Fish are threatened by overfishing as well as their habitat getting destroyed.

What does a fish look like on down imaging?
On fish finders with down imaging technology, fish show up as dots rather than arches. This is because down imaging sonar uses a narrower sonar cone, and only shows a small section of what’s under your boat when fishing.

What do fish look like when they sleep?
It’s pretty easy to tell when fish are sleeping: they lie motionless, often at the bottom or near the surface of the water. They are slow to respond to things going on around them, or may not respond at all (see some sleeping catfish here). If you watch their gills, you’ll notice they’re breathing very slowly.
Aside from how a fish’s eyes are constructed, all fish looking up towards the surface will see a round hole of light. This is known in physics as ‘Snells window’ and is to do with how light is refracted as it hits water – it’s complicated! This means that when looking up, fish can only see through a 97.2° window.
What shape does a fish look like on a sonar screen?
If you will turn Fish Icons off, you’ll see that fish in sonar readings are displayed like arches or lines. The thickness of those lines/arches is the indication of how big the fish is.

to allow them to swim & keep breathing. Sharks do not show up on a fish finder either, No you could have ten dozen Sharks under your boat and not one would show up.
What color are fish on sonar?
The size of a fish is determined by the color of the fish arch. For example if you have palette colors yellow, blue and red. The more yellow you see the bigger the fish. The thickness of the fish arch also determines fish size.
On one end of the spectrum, reds and oranges are most readily absorbed in water, so these colors are most visible in shallow water. Darker blues and purples penetrate the deepest. Yellow and greens are in between.
Can fish navigate in dark?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
What does green mean on deeper?
Green colors – vegetation or silt. You might also see green colors as a horizontal line going across the bottom – this means the bottom is very soft, made of mud or silt.
