What fish is attracted to urine?
The candiru (carnero in some Spanish‐based accounts)
is known as a little fish keen on entering the nether regions of people urinating in the Amazon River.
Does peeing in the ocean attract fish?
No reaction. From a scientific standpoint, Esbaugh says that
it's “definitely not true” that sharks are attracted to urine
, and he assumes the rumor got started because many animals use scent to track their prey. But he says this doesn't hold up because humans aren't the most common meal for sharks. Fish are.
Is it OK to pee in a lake?
Human urine contains something called nitrates, which can cause increased algae in the water, making it toxic to the fish and other wildlife. “
Urine, although sterile, is considered a biohazard and should be discarded appropriately
. Water treatment plants help us to have safe, clean drinking water.
How do you prevent candiru fish?
These fish may not prey on victims through scent, but they can detect movement. If you're in a large pool of candiru, stay still, and you may stay off their radar.
Try tossing a nearby object away from you to disrupt the water
. But if this fish does attach itself to you, try moving to the shore.
How do you prevent Candirus?
There are many troubling stories from the region regarding human run-ins with the candirú. It is not uncommon for people swimming or bathing in the river to urinate while in the water, an action which
creates tiny water currents that are rich in urea and ammonia
, much like an exhaling fish.
A shark's sense of smell is powerful – it allows them to find prey from hundreds of yards away.
Menstrual blood in the water could be detected by a shark
, just like any urine or other bodily fluids.
Well, we contacted the world experts from the International Shark Attack File in Florida. Like us – they found
no evidence urine attracts sharks
.
But are they attracted to blood or urine? Sharks are attracted to blood in the water. While they can smell human urine,
they aren't particularly interested in it
. Any tasty, smelly odorant is likely to get a shark excited but their sense of smell is no better than that of a tuna, and tiny amounts will go unnoticed.
Dr. Alicia Jeffrey-Thomas, a Boston-based doctor of physical therapy, told her 467,000 followers you shouldn't pee in the shower because
it can train your brain to associate the sound of running water with urinating
.
But scientists have long known that
bacteria can swim against currents
. Those upstream swimmers can cause problems when they wend their way into medical devices. For example, 75% of hospital urinary tract infections occur in catheters, despite their outward flow of urine, according to the Centers for Disease Control.
Every family has an overachiever. For fish, that title goes to
manta rays
. They're giant, charismatic and basically geniuses. Mantas have huge brains — the biggest of any fish — with especially developed areas for learning, problem solving and communicating.
Most commonly, fish popeye is caused by an injury, an infection, or poor water conditions in the aquarium
. Another cause of popeye is an infection. 1 This is most likely seen in both eyes. Infection may be caused by a variety of organisms, including bacteria, fungi, and parasites.
Reproduction. It is assumed that candiru
breed multiple times during their breeding season
. Breeding season for this species is unknown but females with ripe ovaries have been collected in December.
On the freshwater side,
the vampire fish is a nickname for the payara, an abundant gamefish found in the Amazon Basin
. While this large, 1.5-to-3 foot fish does not suck the blood of its prey, its six-inch-long fangs, which protrude from an undershot jaw, result in a face only a (payara) mother could love.
Studies have shown that
men rate women's smells and looks as more attractive during fertile periods of a women's menstrual cycle.
Assuming all pee goes to the ocean, and an average output of
1400 ml per person per day
(The internet says 800-2000 so that's what we've got). That would be 511 liters per person per year.

Yes and no
, according to fishing pro Tom Redington. Since sound doesn't travel well between air and water, loud talking or screaming will be barely noticeable to the fish underwater. They won't get spooked or scared. However, sound that occurs underwater is loud and travels fast.
