Where do freshwater fish get most of their water from?
Fish do absorb water through their skin and gills in a process called osmosis. Osmosis is the flow of water across membranes from areas of low concentration of dissolved things (solutes) to areas of high concentration.
Where would you expect a freshwater fish to get most of its water from absorption?
Freshwater fish- gain water through gills and skin while losing ions to the water they do not drink water. osmotic water gain through gills and surface of body.
Where do fish get their water from?
Most fish that live in the ocean tend to lose water–the high salt content of the ocean causes water to constantly flow out through the fish's gills. So fish need to drink lots of seawater to stay hydrated.
Where do fish live in freshwater?
Some fish cannot live in areas where there is much salt and others need salt in the water to live. However, some fish can live in both saltwater and freshwater! Freshwater contains much less salt than the ocean. Most ponds, reservoirs, and rivers across North America are freshwater.
Where does freshwater come from?
Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater.
Do fishes fart?
If you consider farting to be the by-product of digestion – in other words gases expelled from the rear end – then most fish don't fart. However there are two exceptions, the shark and the herring.
Do fishes cry?
"Since fishes lack the parts of the brain that set us apart from the fishes — the cerebral cortex — I doubt very much that fishes engage in anything like crying," Webster told LiveScience. "And certainly they produce no tears, since their eyes are constantly bathed in a watery medium."
How are freshwater fish adapted to their freshwater surroundings?
How are freshwater fish adapted to their freshwater surroundings? – They excrete a small volume of very salty urine. – They excrete salt through specialized cells. How are saltwater fish adapted to their saltwater surroundings?
How do fish get in lakes?
Fish either reach new lakes and ponds through external help, or the creatures stay there, survive the period of drought, and then thrive again when water is plentiful.
Where do most fish live?
Nearly half of all fish species live in fresh water, which means they swim in the rivers, lakes, and wetlands that make up less than 3 percent of Earth's water supply. There are more than 800 known freshwater fish species in North America alone.
What is a fresh water source?
Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater.

Where do fish adapt to their environment?
Many fish have color patterns that help them blend in with their environment. This may allow the fish to avoid being seen by a predator. Some fish, such as the flat fishes (Pleuronectiformes), can change their skin coloration to match the surrounding habitat. Fish can also have disruptive markings to hide body parts.
Do fish ever fart?
If you consider farting to be the by-product of digestion – in other words gases expelled from the rear end – then most fish don't fart. However there are two exceptions, the shark and the herring.
How do fish get in the rivers?
Over longer time periods, movement of fish between basins is often facilitated by "headwater capture." This is when a river tributary cutting its way upstream toward the divide between basins causes enough erosion to cut through that divide, thus serving as a waterway between two rivers.
Where do fish live in lakes?
Lakes and ponds may have shoreline structures such as docks, logs, stump fields, brush, rock piles, grass beds, and downed trees that provide shelter, shade, and protection for fish. Islands, sand bars, rock piles, and log jams in rivers and streams are also good places to fish.
Which is freshwater fish?
Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of salinity.

Where is the most freshwater located?
ice and glaciers And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Another 30 percent of freshwater is in the ground. Fresh surface-water sources, such as rivers and lakes, only constitute about 22,300 cubic miles (93,100 cubic kilometers), which is about 1/150th of one percent of total water.
Where are the most freshwater lakes?
Most of the planet's freshwater lakes are situated at higher latitudes in the Northern Hemisphere. It has been estimated that there are at least 2 million lakes in Canada, out of which 31,752 lakes are larger than 3 sq. km and 591 lakes are more than 100 sq. km.
Can you taste a fart?
You won't be able to taste a fart that escapes through your mouth. Flatulence is made up of swallowed air and gas produced by bacteria in the colon from undigested carbohydrates. It smells bad due to the breakdown of various foods into certain gases, primarily sulfur-containing gases.
Do girls fart more than boys?
Although women and men produce the same amount of flatulence, a study conducted by Dr. Levitt found that women's farts consistently contain significantly greater concentrations of hydrogen sulfide — the stuff that makes them smell.
How do fish adapt to freshwater?
(Fig. 4.1) A physiological adaptation found in fish that enables some fish species to live in freshwater and others to live in saltwater is called osmoregulation. This is where fish regulate their intake of saltwater or freshwater to keep their fluids, such as blood, from becoming too salty or too dilute.
Can a fish drown?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don't technically drown, because they don't inhale the water, but they do die from a lack of oxygen. Fishing equipment, such as some types of hooks, can damage the gills.
