Fish

No, fish do not cry in the same way that mammals do. They do not produce tears to express emotions like sadness. However, they may exhibit stress or discomfort through other behaviors such as erratic swimming or changes in color.

A corrie fish is a small freshwater fish native to Europe. It is typically found in cold, rocky streams and lakes. The corrie fish has a distinctive appearance, with vibrant coloring and small size, making it a popular choice for aquariums.

sedimentary, as clear fish imprints are often found in sedimentary rocks formed by the accumulation of sediment over time. Sedimentary rocks can preserve fossils and imprints due to the gentle burial process that allows for the preservation of organic remains.

yes actually it is the oldest known class in the world. About forty sixth graders, thirty- six seventh graders and about eighteen eighth graders even know that. only because they are truly gifted and foun out from their teacher and classmates!

Actually the genes for this kind of protein is widespread in nature occurring in both plants and animals, all kinds of animals including fish, insects, crustations. This would indicate that this protein occured early in evolution. This makes sense as the need to protect things that live in the cold and are mostly water would have occured throughout life's history on a planet where the temperature is and has been only a few degrees (remember even 500 degrees is not all that much astronomically) higher than the freezing point of water.

Yes, there are often limits in place to regulate fishing activities, such as catch limits, size limits, and closed seasons to protect fish populations from overexploitation. These limits help maintain sustainable fisheries and protect the overall health of marine ecosystems.

The Haida people used wooden fishing hooks, baited with herring, to catch fish. They also utilized harpoons and fish traps made from cedar branches to catch fish in the rivers and along the coastline. Additionally, Haida fishermen used canoes to navigate the waters and catch fish.

The blobfish appears pink or reddish in color when it is deep-sea dwelling due to the lack of pigmentation in its skin and the pressure of the deep sea.

Shooting fish in a barrel is considered very easy because the confined space of the barrel makes it difficult for the fish to escape, resulting in an almost guaranteed hit for the shooter. The saying "like shooting fish in a barrel" is used to describe a task that is extremely simple or effortless.

In 1996 it was about 120 million tons. Up from about 20 million tons in 1950.

Salmon can live both in groups and alone. They are known to form schools, especially during migrations, spawning, or feeding. However, they can also be solitary when searching for territories or during periods of rest.

Flying fish are typically found in surface waters of the ocean, where they can leap and glide to escape predators. They are not deep-water species and do not live at great depths. Flying fish generally stay within the top few meters of the water column.

hi

you can not just tip it out and replace it

it will kill your pets

BUT you can buy the aqua leash from online sites and good toy shops to clean the bottom of the tank.

another way is to remove a little fraction of water from the tank and replace it with bottled or distilled water.

but be carefull!

make sure the temperature of the new water is the same as the tanks water!

The main function of the dorsal fin in any animal with a dorsal fin is stability. Some fish have adapted for using the dorsal fin for other uses, such as propulsion in the Sunfish. The anglerfish's dorsal fin has evolved to work as a fishing pole so that the fish can bait and catch their prey.

Their are certain ways of stopping fish from eating your tadoles firstly you shouldn't be keeping tadpoles in the same place where fish hang around. Tadpoles are water animals so if you want to keep the fish away from eating tadpoles the best way is to find a water based thiing for example a condom. A condom is water based so tadpoles will live in it and fish are afraid of plastic. for some reason but it sounds strange and weird but its the truth

Yes, Lake Texoma is known for its diverse fish population, including species like striped bass, largemouth bass, catfish, and crappie. It is a popular destination for fishing enthusiasts due to the abundance of fish in its waters.

The scales. It's not the head, tail, or anywhere else.

The backbone of a fish, also known as the spine, provides support and structure to the fish's body. It also protects the spinal cord, which is essential for sending messages between the fish's brain and body, allowing it to move and function properly.

Salmon have an endoskeleton, which is an internal skeletal system made up of bones and cartilage. This endoskeleton provides support and protection for the salmon's organs and muscles, allowing them to swim efficiently.

Bony fishes achieve buoyancy through an air filled sac called a swim bladder. The bladder controls the fish's buoyancy by varying the gas pressure inside the fish's body to allow it to sink or rise in the water.

Chondrichthys, or cartilaginous fishes (sharks, skates, rays) achieve buoyancy in other ways because they do not have swim bladders. They do this 3 ways:

1. Store low-density compounds in the body. They store various lipids in throughout their bodies ,which have lower densities than seawater. Squalene is one lipid that is stored in the liver of sharks.

2. Reduction of dense tissues. Chondrichthys do not have replaced bones with cartilage, which helps them reduce their weight in the water. Cartilage is 1/2 as dense as bone. They also reduce muscle mass and protein content. They also increase water content of tissues .

3. Dynamic lift. Sharks can generate lift by their swimming motion. They have a heterocercal tail with a larger dorsal lobe than the ventral lobe. This tail generates lift on the posterior end of the fish, but pushes the anterior end down. This is corrected by having large pectoral fins. This positive attack angle generates head lift. The head of a shark is also flattened dorsoventrally and counteracts the tendency for the tail to push the head downward.

The disadvantage of the Chondrichthys methods of buoyancy is that it is difficult for them to adjust their buoyancy and low density lipids are energetically expensive to make. Dynamic lift requires constant forward motion. They must keep swimming, which can also cost a lot of energy.

Bromothymol blue is typically used. That can be purchased at most pet shops. The trouble with an ick infection is that by the time you see it, it has grown throughout the fish's body and there isn't much that will save it. You can also try quarantine so the rest of the fish in the aquarium don't come down with it.
