Heard that geckos urine is poisonous and cannot be touched? But who has ever seen what geckos urine looks like?

Geckos do not urinate alone, and their "urine" is always excreted along with feces. The gecko's cymbal is a columnar that is half white and half black and does not turn into water. The available research evidence has shown that the geckos in China are not toxic and there are no cases of spreading diseases.

1. Which lizards are poisonous? Are geckos poisonous?

Lizards are a large group of reptiles, with more than 6,000 species, but in fact there are only a few known species of poisonous lizards, such as the Sheila of the genus Poisonous Lizard, the Mexican Poison Lizard, and the Comodo Monitor Lizard of the Monitor Lizard Family, and even fewer species have venom glands that can secrete venom. Existing scientific research proves that some lizards do have primitive venom glands similar to those of venomous snakes, but they do not secrete venom, so naturally we cannot classify these lizards into the category of "poisonous". Therefore, there are indeed poisonous lizards in the world, but there are very few species.

After talking about poisonous lizards, let's talk about geckos. Taxonomically , geckos are a collective term for small and medium-sized lizards belonging to the reptile family Ofquales , with about 1,000 species , while known species of the gecko family are non-toxic. Geckos have no poisonous fangs or glands that can secrete venom, and geckos that have been discovered by humans are non-toxic.

2. Will geckos urinate? Is gecko urine poisonous?

First of all, we need to clarify the concept of "urine", in general, urine or urine refers to the fluid excrement of human beings and other vertebrates that is excreted from the body through the urinary system and urinary tract for the needs of metabolism. Humans and other animals can regulate the electrolyte balance in the body, excrete metabolic waste, and maintain the relative stability of the internal environment through urination. Although the excretion mechanism and purpose of different animals are roughly similar, the process of excretion and the things excreted are various. Mammals, fish, and amphibians, including humans, excrete urea, while reptiles and birds urinate uric acid, including geckos who are members of reptiles. Geckos, unlike humans, do not have a body reserved for urination, their intestines, urethra and reproductive tract share the same outlet, this structure is called the cloaca, that is, geckos do not urinate alone, their "urine" is always excreted along with feces.

So what does excrement from a gecko look like? If you've ever found some columns on the walls that are half white and half black, then you've probably seen geckos, and the black part is the gecko's feces, and the white part is the uric acid that the gecko excretes with the feces. The uric acid that the gecko has just excreted from its body is semi-solid paste, which will harden rapidly after contact with air and will not turn into water.

Schematic of gecko feces

Therefore, "the excrement of the gecko is poisonous, some people in the eaves, corners or platforms, accidentally on the hands will be stained with liquid like water, usually people will be stained with gecko urine after the skin itching, redness, rash and other conditions" The statement is not scientifically based, and the gecko generally does not directly discharge liquid urine. Moreover, for healthy people, the uric acid excreted by geckos is not skin toxic, and even if it is accidentally swallowed, it will not cause serious poisoning reactions. The available research evidence has shown that the geckos in China are not toxic and there are no cases of spreading diseases.

At this point, we can conclude that the statement that "geckos urine is poisonous" is a rumor.
