When were puffer fish discovered?
Puffer fish have been known to humans for centuries. The exact timeframe of their discovery is unclear, but they have been referenced in ancient texts and historical records from various cultures around the world. Modern scientific classification and study of puffer fish began in the 18th century.
Can brine shrimp survive in a biosphere?
Yes, brine shrimp can survive in a biosphere as they are resilient and adaptable creatures. As long as the biosphere provides the necessary conditions such as appropriate temperature, salinity, and food source, brine shrimp can thrive and reproduce within the controlled environment of a biosphere.
We see color in the electromagnetic spectrum because different wavelengths of light correspond to different colors. Our eyes have specialized cells called cones that are sensitive to different wavelengths of light. When light enters our eyes, the cones are activated, sending signals to our brain that allow us to see and interpret colors. Ultraviolet, infrared, X-rays, and gamma rays are outside the visible spectrum, so we cannot see them as colors, but rather, we use specialized sensors or equipment to detect and interpret them.
Haddock fish are typically a grayish color with a white underbelly. They may also have a slight hint of green or blue on their backs.
A respiratory medium is a substance that facilitates the exchange of gases during respiration. In many organisms, including humans, air is the respiratory medium that allows oxygen to be taken in and carbon dioxide to be expelled. In aquatic organisms, water serves as the respiratory medium for gas exchange.
While some species (Goldfish etc) have been selectively bred by aquarists for their colour the majority of fish have colours to help them stay alive or find a mate in some way. In some species it makes them stand out because they are poisonous and their colours stop other creatures from attacking them. This preserves the lives of both the potential hunter and the hunted. All fish need to hide for one reason or another and camouflage is a main reason for most colours.
Where can you buy puffer fish food?
You can buy puffer fish food at pet stores that specialize in aquarium supplies. Look for food specifically designed for puffer fish, such as small snails, shrimp, or specially formulated pellets. You can also find puffer fish food online through various websites that specialize in aquarium supplies.
The angelfish species overall is not considered endangered. However, specific species of angelfish may be threatened or endangered due to factors such as habitat loss, overfishing, and pollution. It is important to protect their habitats and regulate fishing practices to ensure the conservation of these species.
What is the swim bladder used for and how does it work?
- Swim bladders are located in the center of a fish's body in order to help the fish's balance and swimming ability. According to the book "Goldfish", some fancy goldfish like the lionhead are poor swimmers because their swim bladder is located too far forward. When the fish wants to go up, a pneumatic duct opens to let in oxygen to swell the bladder up like a little balloon. By gulping, the fish can help fill up the bladder. Some fish, like the rudd, have two swim bladders.
- When the fish wants to swim lower, they deflate their swim bladders. The gas is absorbed into their gas glands, which are located on either side of the swim bladder. The fish's body can also use the gas glands to help inflate the swim bladder. Fish can also expel excess gas from their mouths in something similar to a belch. Also, if fish are caught in oxygen-poor water, they can use some of the oxygen in the gas glands or swim bladder to help them breathe. According to the Encyclopedia Britannica, some of fish species like sharks use oil instead of gas to inflate or deflate an area in the liver, since oil is lighter than water.
- If a fish is swimming sideways, is unable to rise to the surface or is clearly having trouble swimming, chances are it is due to swim bladder disorder. If a fish is constipated, this could press the digestive organs against the swim bladder, not allowing it to inflate properly. According to HealthyBetta.com, a fish that has swim a bladder disorder should go on a fast for a day and not be fed so much in the future. Also, splitting the feedings to two or three a day is better on the swim bladder than one large feed per day.
No mollies are omnivores they eat almost all fish food even algae.
What helps draw water into the mouth of bony fish?
Bony fish use a process called buccal pumping to draw water into their mouths. By expanding their buccal cavity, they create a negative pressure which pulls water in. This helps them breathe by passing water over their gills for oxygen exchange.
Is carbon monoxide harmful in fish?
Every poison has a particular trait that causes it to be poisonous. In the case of carbon monoxide, the trait has to do with hemoglobin in the blood.
Hemoglobin is made up of complex proteins that bind to iron atoms. The structure of the protein and its iron atom causes oxygen to bind to the iron atom very loosely. When blood passes through the lungs, the iron atoms in the hemoglobin bind to oxygen atoms. When the blood flows into areas of the body that are lacking in oxygen, the iron atoms release their oxygen. The difference in oxygen pressure in the lungs and in the parts of the body needing oxygen is very slight. The hemoglobin is very finely tuned to absorb and release oxygen at just the right times.
Carbon monoxide, on the other hand, binds very strongly to the iron in hemoglobin. Once carbon monoxide attaches, it is very difficult to release. So if you breath in carbon monoxide, it sticks to your hemoglobin and takes up all of the oxygen binding sites. Eventually, your blood loses all of its ability to transport oxygen, and you suffocate.
Because carbon monoxide binds to hemoglobin so strongly, you can be poisoned by carbon monoxide even at very low concentrations if you are exposed for a long period of time. Concentrations as low as 20 or 30 parts per million (PPM) can be harmful if you are exposed for several hours. Exposure at 2,000 PPM for one hour will cause unconsciousness.
Many common devices produce carbon monoxide, including cars, gas appliances, wood stoves and cigarettes.
Can it Rain fish from hurricane?
Yes, it is possible for hurricanes to sometimes "rain" fish or other marine animals if they pick them up from bodies of water and carry them inland before dropping them back to the ground. This phenomenon is known as "animal rain" and has been documented in various hurricanes throughout history.
What is special about the lifestyle of salmon?
The life cycle of a Salmon starts in a fresh water stream. After hatching the fish swims to the sea where it spends almost all of its life. Finally it returns back to the spot it was born; the fresh water stream, & to reach it, it even has to swim up the falls. This is only where it would have sex or lay eggs again.
What is the habitat of the lionfish?
the aphotic zone.... but where in the aphotic zone???
At depths of 3000 meters, where no sunlight can penetrate. It survives thanks to its bioluminiscent crest on its head and by its stomach that it can make three times bigger than itself.
How many eggs does a sea anemone lay?
Sea anemones do not lay eggs. They reproduce sexually by releasing sperm and eggs into the water, where fertilization occurs. The fertilized eggs develop into larvae, which eventually settle and grow into new sea anemones.
What Arctic animals eat seaweed?
Arctic animals that eat seaweed include walruses, some species of seals, and certain species of fish such as the Arctic cod and the Arctic char. These animals rely on seaweed as a source of food and nutrients in their cold, harsh environment.
Salmon fishing is the recreational or commercial activity of catching salmon fish from rivers, lakes, or oceans using various methods such as fly fishing, trolling, or drift fishing. Salmon fishing is popular for its challenging nature and the prized culinary value of salmon.
Is a mudskipper a herbivore or a carnivore?
Mudskippers are carnivores. They eat small crabs, worms and insects.
In what year was the beluga sturgeon listed as endangered?
The International Union for Conservation of Nature (IUCN) placed the Beluga Sturgeon, Huso huso, on it's Red List, as "Endangered", in 1996. The U. S. Fish and Wildlife Service (USFWS) currently lists The Beluga Sturgeon Huso huso, as "Threatened". They also have a proposed rule (67586) that, also, would finally list these animals as endangered.
Salmon are anadromous fish, meaning they are born in freshwater, migrate to the ocean to mature, and then return to freshwater to spawn. They spend most of their life in the ocean but require freshwater for reproduction.
