It seems to me the only land animal that can't swim is the land tortoise. I am only saying this because I believe it is too heavy to say afloat and its feeble arms and legs couldn't possibly displace enough water to keep it's head above water. Other animals might include: Coral and some insects (seems like they just drown).

When a fish dies, its body undergoes decomposition where bacteria and other organisms break down the tissues. This process releases nutrients back into the water and contributes to the food chain. Over time, the fish's body will be fully broken down and recycled by other organisms in the ecosystem.

Marlin and Dory were swallowed by a whale in the movie "Finding Nemo".

Fish develop externally, meaning that fertilization and embryonic development occur outside of the parent fish's body. The eggs are often released into the water where fertilization takes place, and the embryos develop independently until they hatch.

Snakehead fish were introduced to the US primarily through the aquarium trade and by food markets in Asian communities. Some snakeheads were released into local waters by hobbyists, leading to established populations in certain areas.

A fish could suffer from hypoxia if there is a decrease in oxygen levels in the water, which could be due to pollution, algal blooms, or changes in temperature leading to decreased oxygen solubility. This can cause stress, difficulty breathing, and ultimately harm the fish's health and survival.

Several years. It is more reliable to say that Black Ghost Knives are mature at 15-18 cm (6-7 inches) long.

Some types of fish found in the Coromandel Zone include pomfret, mackerel, sardines, and anchovies. These waters are also known for supporting a diverse range of marine species such as tuna, barracuda, and snapper.

1. 35.5 inches: This length is the most accurate as it matches the actual size of the Chinook salmon.
2. 3 feet: This conversion is less accurate but still provides a general idea of the size of the salmon.
3. 91 centimeters: This metric measurement is slightly less accurate than 35.5 inches as it is a rounded approximation.
4. 3 yards: This conversion is the least accurate as it greatly overestimates the length of the Chinook salmon.

The Chondrichthyes are the cartilaginous fishes including the sharks, rays, skates and chimaeras. The Osteichthyes are the bony fish. Both of these groups became established during the Devonian Period about 400 million years ago. The Chondrichthyes differ from the Osteichthyes in many respects, including their skeletons, scales, teeth, buoyancy, swimming, gills and reproduction. Skeleton: The Chondrichthyes have a skeleton of cartilage, composed of chondrocytes suspended in a protein matrix. The Osteichthyes skeletons' are composed of cartilage and bone. Scales: Cartilaginous fish have large scales called placoid scales. These have a bone like base embedded in the skin and a backward projecting enamel covered dentine spine. The whole thing has a central pulp cavity ( rather like the structure of teeth). The epidermis and dermis form placoid scales. In bony fish the scales are formed only by the dermis. The majority of modern bony fishes have cycloid or ctendoid scales. These lack enamel and dentine and both have overlapping design where the anterior part of the scales is overlapped by the posterior portion of the scale in front. Cycloid scales are smooth, flat and round. Ctenoid scales are similar to cycloid scales except that the posterior edge also possesses a row of comb-like extensions (ctenii) which are believed to reduce drag during swimming. As a fish with cycloid or ctenoid scales grow the scales also grow. In summer when food supplies are abundant the fish grow rapidly, and so do the scales. In winter growth slows, and it is this difference that produces concentric growth rings (annuli). These rings can be used to age fishes. Teeth: In Chondrichthyes the teeth are confined to the jaws and are embedded in the gums. They have the same basic structure as the placoid scales. They occur on ligaments and are replaced as they get worn-the new teeth grown on the inner face of the jaw and gradually move up to the jaw edge, row upon row, pushing out the old worn teeth. They work as opposing saws- hence sharks wriggle their whole body when shredding prey. In Osteichthyes the teeth are not confined to jaws. In nearlly all bony fish the teeth are shed one by one and replaced by new ones growing up in the same place. Buoyancy: In Chondrichthyes the pelagic forms remain buoyant by producing large amounts of oil, called squalene, in their livers. They can undergo extensive vertical migrations because oil does not compress/expand much with changes in pressure. In Osteichthyes buoyancy is often by a swim bladder, a lunglike, gas-filled organ. Swimming: The cartilaginous fish can swim forward only. Bony fishes can swim forward and backward. Gills: Both cartilaginous and bony fish have gill slits but the bony fish also have gill covers (an operculum). Reproduction: In the Chondrichthyes the males have claspers which assist in copulation. Fertilisation is internal-almost unique among fish. They have elaborate courtship rituals, males often bite onto the female to assist during copulation and females have thicker skins to protect against such amour. There is varied development of the eggs: Some lay them on substrates- oviparous. They eggs are large with hard shells and a large amount of yolk, taking up to a year to hatch as minature adults. They are called mermaid purses. Some species retain the developing eggs in the uterus- ovo-viviparous. In these the young are nourished by yolk in a yolk sac and live in the oviduct until birth as mini adults. In a few species there is true vivparity where nourishment is supplied directly to the developing embryos by the mother. Most cartilaginous fish mature at 6-18 years old but a few such as lemon sharks do not mature until they are 24 and spiny dogfish do not mature until they are about 35 years old. They also produce relatively few young. These two factors cause them to be vulnerable to over-exploitation and many of the shark species are now endangered. In bony fish the males do not usually have a special copulatory device. Most species are oviparous and fertilisation is external. Some species are sexually mature at one year old or less. Generally, smaller species mature at a younger age and the larger species become sexually mature at a few years old.

When a fish is floating at the surface of the water, it could indicate a problem with its swim bladder, which helps control buoyancy. This could be caused by factors like infection, overfeeding, or poor water quality. It's important to address the issue promptly to ensure the fish's well-being.

Most fishes never come to the surface for air. Most 'breath' water, extracting oxygen from water they pump across their gills. Frequently fish in oxygen depleted water will rise to the surface and take in water from just below the surface because there is usually a higher concentration of oxygen there. Fish 'gasping' at the surface of an aquarium or pond usually indicates that the water quality has deteriorated.

There are some fishes with specialized gills that allow them to breath air directly, and obtain some of their oxygen in that manner. These fishes usually are found in water with normally low oxygen levels, as may be found in bogs and swamps. The ability to breath air directly sometimes diminishes the ability some species to obtain all of their oxygen from the water, so these fish usually need to visit the surface periodically each day.

There are also obligate air breathers who must obtain most of their oxygen from the air. Lungfish are an example. Mudskippers are another example of air-breathing fish. Such creatures are, however, unsuited for life on land, and must exist at least partially in the water. There is a great variety of adaptation and variety among fishes in breathing and related activities. Even air breathing fish must remain moist at all times. The ability of fishes to breath air and/or water covers a broad spectrum, generally dictated by environmental factors.

Salmon spawn in various rivers throughout the UK, including the River Tweed, River Tay, and River Severn. These rivers provide suitable conditions for salmon to lay their eggs and complete their lifecycle. Protection and conservation efforts are in place to ensure the sustainability of salmon populations in these areas.

the relationship is that the anemone is dangerous to other fish but the clown fish is immune to its shocks so the anemone houses the clown fish and it eats the clown fish's waste

Some predators of the Halfmoon fish include larger fish, sea birds, and marine mammals such as seals and sea lions. These animals prey on the Halfmoon fish in their natural habitat, which includes kelp forests and rocky reef environments.

Fish in schools typically eat a variety of small aquatic organisms such as plankton, algae, insects, and small fish. They may also feed on detritus or plant matter depending on their species and habitat. The group feeding behavior of schooling fish allows them to efficiently locate and consume food resources in their environment.

No, it is not safe to eat sai-sai fish as they are often poisonous and can cause serious health issues if consumed. It is best to avoid eating sai-sai fish to prevent any adverse effects on your health.

The piano tuna

If a silver molly fish is lying on its side at the bottom of the bowl, it may indicate a health issue such as swim bladder disorder, poor water conditions, or stress. It is important to monitor the fish closely, check water parameters, and consider consulting a veterinarian specializing in fish health for proper diagnosis and treatment.

These are saw toothed scales. One of the fish that has this kind of scale is the American Bass.

It depends on the maturity and species. Since you didn't mention a species, I can only give you an average weight.

- Dwarf puffer fish only weigh just under an ounce. Depending on the species of the dwarf puffer fish

- Ordinary puffer fish can weigh 20-30 lbs (9-13.5kg). Again, depending on the species.

The oarfish is the longest bony fish in the ocean, also known as a ribbon fish. It can grow up to lengths of over 50 feet and is typically found in deep ocean waters. Oarfish are known for their elongated, ribbon-like bodies and distinctive red fins.

Freshwater crabs can be aggressive and may attack betta fish, especially if they are small. It is not recommended to keep them together in the same bowl to prevent any harm to the betta fish. They have different care requirements and tank setups.
