Well, you see, a Greek philosopher once realized that if you filled a bathtub until it was completely full and put something in, the bigger it was, the more water would spill out. So to figure out their weight, fish have a natural instinct which enables them to calculate their exact mass based
noononono its a joke duh it uses its scales lol
fish
The fish uses its colour as camouflage. The fish also has the ability to hide in small holes against predators.
They swim around and eat whatever they feel like eating. They get it them selfs.
They tend to swim away when they feel movement
There is no standard-size package for fish. It should weigh whatever is on the label.
oar fish weigh about 600 pounds (272 kilograms)
Because a fish has its own scales.
It really depends on the fish.
a lot
That depends on the weight of the fish as compared to the weight of the water their bodies displace. If it's a heavy, dense fish, then the tank with the fish would weigh more. If it's a light, less dense fish, then the tank with water only would weigh more. This assumes that the water displaced has been removed from the tank, right? If you are adding the fish to the water then I think it should increase the weight regardless of the density of your fish. The question then might be, does the fish weigh less when it is swimming than it would on a dry scale?
how do black caiman defend them selfs
a flying fish weigh 3~6pounds. 8~9pounds if it's big as a koala.
