Fish

Carp can live up to 20-30 years in the wild, but in captivity or recreational fishing environments their lifespan may be shorter. Factors such as water quality, diet, and environment can influence their longevity.

Marlins typically live up to 10-15 years in the wild, although some have been known to live longer. Factors such as habitat, food availability, and predation can influence their lifespan.

The response of receptor cells to odorants is, like other neuronal cells, variable depending on the conditions. There may not be enough of the odorant to stimulate an action potential; scavenger enzymes in the mucus layer may breakdown the odorant particles before they have a chance to bind to the receptor; or the receptor activation may cause an alternative signalling pathway to operate, preventing depolarisation. Even if a receptor does depolarise, it will eventually become adapted to the presence of the odorant and stop reacting to it. This is why, on encountering a strong smell that initially overwhelms you, after a few minutes you will fail to notice it any more. However, if you were to suddenly take a sharp intake of breath, you'd become aware of the smell again; the action of suddenly inhaling odorant-laden air exposes more of the olfactory epithelium to a greater amount of stimulus, which results in more action potentials.(smell@Everything2.com)

Puffer fish typically live for about 5 to 10 years in the wild, but some species have been known to live up to 20 years. In captivity, they can live even longer, sometimes reaching up to 15-25 years depending on the species and quality of care provided.

Arctic Cod are meat eaters who prefer hunting at night. Arctic Cod eat other cod, mussels, worms, haddock, and sand eels.

The answer is smelt. Caught in rivers emptying into Lake Superior by net when they swim up stream to spawn.

Clownfish are found in warm waters of the Pacific and Indian Oceans, typically in coral reefs and lagoons. They form symbiotic relationships with certain species of sea anemones, where they find protection and shelter.

Little fish can get eaten by larger fish, birds, marine mammals, and even some larger invertebrates like crabs and octopuses. They are an important food source for many predators in aquatic ecosystems.

Fish don't have money as they do not use currency or have a concept of ownership. They live in water environments where currency is not needed for survival.

The coelacanth was thought to be extinct until 1938 when one was caught off the coast of South Africa. Previously only known from the fossil record, its discovery was a significant scientific find.

Pufferfish can live up to 10-15 years in the wild, with some individuals possibly living longer. However, due to various factors such as predation, environmental conditions, and human interference, it is difficult to determine the exact age of the oldest pufferfish.

If your fish is listing to one side, it could be a sign of a swim bladder disorder, which can be caused by overfeeding, issues with water quality, or internal infections. It's important to check water parameters, ensure proper diet, and consider treating for any underlying infections if necessary. Consulting a veterinarian specializing in aquatic animals may also be beneficial for a proper diagnosis and treatment plan.

It depends on the species. Lily Pads have a flat surface area which allows them to float on the surface like a boat as well as having stems that keep growing until they reach the surface and then stop growing. With many Kelp species, they have "float sacs" filled with air which allow them to stay afloat.

Increasing surface agitation, adding live plants, using an air stone or bubble wand, and ensuring proper filtration can help increase oxygen levels in the fish tank. It's important to maintain a balance between oxygen production and carbon dioxide removal to keep the fish healthy.

Some live-bearing freshwater fish include guppies, mollies, platies, swordtails, and endlers. These fish give birth to live young rather than laying eggs, making them popular choices for beginner hobbyists due to their reproductive behavior.

Yes, a fish has weight in water due to the gravitational pull acting on its mass. However, the weight of the fish in water is offset by the buoyant force exerted by the water, which helps keep the fish afloat.

The jelly-like substance is likely fish eggs that the pregnant fish has released. These eggs are fertilized by the male fish and will hatch into baby fish if conditions are right. It is important to provide a safe environment for the eggs to develop if you want to raise the fry.

Most fish lay eggs in water, either attaching them to plants or structures or releasing them into the water. Some fish, like salmon and herring, migrate upstream to spawn in freshwater before returning to the ocean. There are a few exceptions, like the mudskipper, which is able to lay eggs on land.

The inside of a male fish typically contains organs such as the heart, liver, intestines, and swim bladder. Their reproductive organs will also be present, including testes for producing sperm. The specific appearance can vary depending on the species of fish.

Improperly prepared puffer fish can be deadly due to toxins within the fish.

Improperly handled and undercooked fish could be deadly due to microbiological growth.

Some people are deathly allergic to seafood.

But not all fish are deadly to all people.

It is not recommended to physically harm animals in any way. Fish are living beings that should be treated with respect and care. If you have a concern about a fish, the best course of action is to seek help from a professional who can provide guidance on how to address the issue in a humane manner.

Flying fish are not typically dangerous to humans. They use their ability to glide above the water as a way to escape from predators. If startled, they may end up in boats or hit people, but they do not pose a direct threat to humans.

Yeah, a rudimentary brain that controls basic functions of life.

__________

I think they don't have a brain.
