The "Vampire fish" shown is actually a lamprey, which is harmless to humans. Lamprey don't even live within the Amazon, they live throughout North america where they use their strange mouths to latch on to other fish and suck their blood. Vampire fish are an actual fish species found in the Amazon, however, they are not a species of catfish and do not mutilate your reproductive organ. The species of fish he describes here, the Candiru, is a small species of catfish that lives in the Amazon and is RUMORED to swim up the male reproductive organ, they are also called the Toothpick fish or Vampire fish, however, the previously mentioned Vampire fish is an entirely different species than the Candiru.

Worth mentioning that the Vampire fish/Candiru section is incorrect. Candiru are indeed catfish and have spines, but they don't look like eels or have concentric circles of teeth. The photograph in the section is actually of a lamprey, which does have these features, but lampreys are much larger, don't attack prey in this way, and don't have backwards-facing spines. Instead, they latch on to the outside of their prey - usually larger fish - and use their teeth to bore into their victim's flesh.

The first parasite is bs though. The imahes shown are those of a lamprey who is harmless, the actual parasite is named candiru.

[@1._-1]

but no sign up and no credit card, 4/10 would not recommend.

[@cutthroatEntropy]

the vampire fish one is bs though. the fish hes talking about is actually called a candiru, and the pictures shown are lampreys. its physically impossible for a candiru to do that and even if it did itd die within a minute of being inside of you.

[@mangantasy289]

super creepy, extremely interesting evolutionwise. Biologist (entomologist/arachnologist) here, and sorry.. I really don't want to be mean, I actually really like your videos, but I just can't help but correct some points. Already the first one, the author mixed up things dramatically. The unfamously known fish attracted by the ammonium in pee and capable of entering your urethra are Candiru. Small species of catfish. Also this actually happens extremely rarely and the specimens doing so a very small. The images (and sketch) though show Lamprey's. These are way bigger (120 cm (47 in) and not(edit: "real fish" but) "jawless fish". It is again very rare, but possible, that they attach to humans. They are not attracted by ammonium. Both animals may be called "Vampire fish" in the vernacular, hence the obvious confusion. And I'm not wanting to be mean, but IF you are putting out this content (which can be very interesting), it might be a good idea to make a detailed fact check. The more so when dealing with somewhat lurid themes. And I'm aware that does not necessarily come natural to non-professionals, but the scientific names really can help to avoid confusion. You did that even in this video, so you can do it. Sandflies, and once more, vernaclar name referring to several pretty distinct families/species. "Fun" fact about the sandflies aka Phlebotomidae=Leishmania parasites vector, foreign soldiers in the Iraquian war actually were badly surprised be these little critters. They simply had been completely ignorant of their existance and the issues they could cause on the troups (in contrary to the native opponents of course). The military had to adapt and find a solution to protect the soldiers. Phlebotomes are actually very bad fliers, so about 1/2 meter nets around the bases did the job quite well. Also why bites occur mostly on the feet and lower legs. Toxoplasma is a protozoan of microscopic size. I might be a little nitpicking here, put choosing a worm as image could be misleading. That aside, extremely fascinating parasite that, just as you said, without any other issue, can have an influence on your risk taking behavious. Studies have found that the percentage of people carrying the parasite is higher in those engaging in extreme sports relative to the average population. Toxoplasma btw does the same to mice. They get bolder, less fearful and are more prone tapproach cats instead of avoiding them. Which of course benefits the parasite, which wants to end up in the cat's body.

Honestly bot flies would be my first choice of parasite if I was to get one, mostly cuz the larvae are prone to bacterial infections so they secrete a natural antibiotic keeping the wound clean. They also mature after a couple months leaving you with almost no damage other than needing therapy.

[@grantarmstrong2968]

The first one, while called the vampire fish, is better known as the candiru, and despite the legends, there is only one somewhat dubious account of such an event occurring. That being said, it is not entirely preposterous as the candiru is known for being a hill parasite, meaning it squeezes into the gills of other fish and feeds off of them
