Yes, fish pee in the ocean constantly, and their urine is a crucial source of nutrients (like nitrogen and phosphorus) that fertilizes coral reefs and seagrass beds, supporting the entire marine ecosystem, even though it's a small percentage of the vast ocean's water volume. Marine fish produce a concentrated urine, expelling nitrogenous waste, while also using their gills to excrete salts, helping them balance their internal fluids.
In the sea, a fish's body is less salty than its surroundings, so it loses water across its skin and through its gills via osmosis. To stop themselves dehydrating, marine fish drink masses of seawater and produce a trickle of concentrated urine.
Did you know that Caribbean parrotfishes and surgeonfishes eat poop? A study released this week in Coral Reefs is the first to document and explain what may be driving this behavior. These abundant fishes are best known for the important role they play on coral reefs by eating algae that can otherwise overgrow corals.
The amount of urea in our pee is negligible compared to the sea's volume. Even if everyone in the world peed in the Atlantic Ocean, urea would still be just. Plus, urea is a way for our bodies to get rid of extra nitrogen from breaking down proteins. Nitrogen is a great source of food for marine plant life.
Most of the ocean remains unexplored (around 80-95%) due to its immense size, extreme darkness, near-freezing temperatures, crushing pressure (over 1,000 times surface pressure in the deep), and the high cost and technological challenges of developing specialized equipment to withstand these harsh, hostile conditions. Sunlight can't penetrate far, visibility is near zero, and deep-sea life is adapted to pressure that would crush most vessels, making direct human study difficult and expensive.
The "21-second pee rule" comes from a scientific discovery that most mammals over about 3 kg (like dogs, cows, elephants) empty their bladders in roughly 21 seconds, regardless of their size, due to physics involving urethra length and gravity. For humans, this serves as a loose benchmark: urinating significantly faster (e.g., under 10 seconds) or slower (over 30 seconds) might signal holding it too long or an overactive bladder, though it's not an exact diagnosis.
So your fish have red worms sticking out of ….. Recently, I have heard stories from customers about red worms protruding from their fish cloaca's or anus. These red worms are called camallanus worms, a parasitic nematode. These nematodes are extremely contagious and should be dealt with when sighted.
The simple answer is yes. Many scientific studies over many years have demonstrated that fish feel pain. To be precise, this doesn't just mean that fish physically react to potentially injurious stimuli, but rather, that they actually experience a sensation of pain.
The NOAA estimates the oceans at 321,003,271 cubic miles or 1.338e21 L (1.3 sextillion). Dividing those out and you get 0.0002%, or 1 in 500,000 parts Human pee.
Pee that's completely colorless and looks like water is a sign that you're overhydrated. (Yep, that's a real thing.) Too much water in your system can dilute your body's delicate balance of water, sodium and electrolytes.
White stringy poop is a symptom of either internal worms and or internal parasites; brown stringy poop is usually just some sort of stomach irritation the fish is experiencing, usually due to its diet.
Fish Don't Know They're in Water - Alameda Education Foundation.
More than 95% of the ocean is left to be discovered. Scientists say that they don't know what species live deep in the ocean or in undiscovered territory, but they say that there should be millions of species to be found.
Fish don't really know they're wet.
Just one person's poop is enough to cause an outbreak. 1 gram of poop, about the weight of a fish hook, can contain millions of virus particles. It only takes 10-100 viruses to get sick. The waste from one person can contaminate an area about the size of 25 football fields.
It has been proposed that fish can feel pain both because they have peripheral nociceptors and because neural responses to noxious stimuli have been recorded in the spinal cord, cerebellum, tectum and telencephalon of fish (Sneddon 2004; Dunlop and Laming 2005).
Fish are capable of rejecting, expelling, or encapsulating hooks. Encapsulation is a process whereby the fishes' healing process causes the hook to be covered with an inert matrix of calcified material; or a-cellular tissue.
Moreover, some vertebrates, such as fish, may lack the neural machinery or architecture to consciously experience (i.e., to feel) noxious stimuli as painful (Key, 2015a).
Stringy poop can be caused by a lack of fiber and fluids in your diet. Some infections can cause stringy poop, but your poop should return to normal when the infection clears. See a healthcare provider if stringy poop lasts longer than several days.
Most blood red blotches on the fins or skin of tropical fish are blood under the skin or hemorrhagic septicemia (“Red Pest”), an internal bacterial disease. The bacteria is generally a gram negative bacteria, with aeromonas bacteria being the chief culprit.
A: Most adults can safely hold their pee for about 3 to 5 hours, but it's best not to wait that long. Holding it too often can irritate your bladder and increase your risk of infection. The average bladder holds 400–600 mL of urine. “Go” when you first feel the urge, especially on long trips.
You might think that elephants take longer to empty their bladders than humans do, because pachyderms are so much larger. But you'd be wrong. Recent research shows that most animals, including humans, take the same amount of time to pee.
