A puddle can be either fresh water or salt water, depending upon the source of the water. Generally, in an environment other than one very near the sea, a puddle would be expected to be fresh water.
In the wild, damselfish generally graze on algae covering reefs. If you are asking in order to figure out what to feed your pet fish... I'm not sure. Marine fish food. Small flakes or small pellets.
Depends on the fish. Tunas and some sharks are known to regulate their body temperatures. Most other fish don't.
if your parakeet stand long hours below in your cage. you can`t put your parakeet in a winter place because they can`t make it to survive. i have a parakeet who died because at the rainy winter place.
yes
Flounders belong to the Actinoterygii class
The Actinopterygii (the plural form of Actinopterygius) constitute the class of the ray-finned fishes.
The ray-finned fishes are so called because they possess lepidotrichia or "fin rays", their fins being webs of skin supported by bony or horny spines ("rays"), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii which also, however, possess lepidotrichia.
Sawfish are Critically Endangered according to the IUCN. Sawfish are illegally hunted for their rostrum, liver oil, and fins. Additionally, they are accidentally fished up in nets. Besides sawfish, many other species are being threatened due to fishing nets. That is why it is best to by line-caught fish.
Depends.
There are predatory sharks like the Great White, Tiger, and Bull Sharks which actively hunt and eat other varieties of shark. There are other species which will not actively hunt other species of sharks, but will feed on an already dead shark. However, there are sharks, like the Whale Shark which do not consume shark meat in any form, because their diet is entirely different.
Many microorganisms are found naturally in fresh and saltwater.
The sea animals that eat red cod are campteropis. These are usually found in the deep parts of the sea and are similar to shrimps in terms of appearances.
It will kill them/it. If you are refering to salt water at the same rate of specific gravity as ocean water wich is about 1.022, Then you will definitely kill your goldfish, It will take between 1/2 and 5 hours. If your goldfish are sick or icky you can dip them in saltwater for about 15 seconds or so and that will actually help them,(possibly) this does not always help but it will not kill.
The Salt
For one, it would be very hard to capture a Whale Shark(as in fishermen). And it is not prey to any known animal.
ofcause they are they have really sharp razor teeths
Humans have been fishing for thousands and thousands of years. We cant be sure.
Hake is a bony white fish, similar to cod or haddock. It is a generally small fish that feeds on plants in the water.
