Because of its small size, the pig-nosed turtle was once considered one of the rarest aquatic turtles in the world. Let us understand this kind of turtle below!

Evolution:
Twenty-five million years ago, a type of turtle called the "shieldless turtle" was widely scattered on the Eurasian land. Including most areas in the eastern part of the country, the scales on their carapace have mostly deteriorated. Some individuals still have a ring of scales on the edge of the plate, but the layered scales are more obvious on the belly carapace. These and Today's pig-nosed turtles are common (the modern pig-nosed turtles also have no scales on the edge of the snout plate), and the modern pig-nosed turtles are the only descendants of the once prosperous shieldless turtles. The novel pig-nosed turtle is its own species and not directly related.
Dispersed:
Only found in freshwater rivers in northern Australia and New Guinea
Body length:
< p> Regarding this issue, there are mixed opinions and no conclusion. Some books say 55cm, some books say 70cm, and some books say 80cm. In general, the pig-nosed turtle is a big guy, at least 50cm. The above is common to Pangu's shieldless tortoises, and shieldless tortoises are generally great.Differences between turtles and turtles:
It can be said that pig-nosed turtles are not completely consistent with turtles and turtles. The main differences between pig-nosed turtles and turtles are: The carapace and plastron of the pig nose are hard rather than soft. Under the skin is a brittle and hard tortoise carapace. The carapace has a developed bony plate edge. The plastron is an obvious layered bony plate, which is brittle and hard. In block form. The difference from turtles is that the body surface is not scales but skin, and the hands and feet are specialized into fins.
Development in the marine pet market:
I first knew that the pig-nosed turtle was entirely because of the arowana. In fact, the popularity of pig-nosed turtles in our country is also thanks to the dragon fish. At first, Malaysia's Xianglong Fishing Ground, Jingang Fishing Ground, and Singapore's Rainbow Fishing Ground and Thousand Lakes Fishing Ground, while producing Asian arowana, took advantage of their location and began to grow precious pig-nosed turtles and use them as background animals. Sold to Konihara arowana enthusiasts because it is the background of dried noble fish such as chili red dragon and over-backed golden dragon. At this time, the pig noseThe price is unusually high. At first in Singapore, the price was $300. According to the most famous arowana dealer in Beijing, around 1996, pig snout also appeared in Guangzhou, and naturally it was sold with arowana, and the price was high. Later, in 1998, pig-nosed turtles also appeared in Beijing and Shanghai, and the price dropped a lot. Since 2000, pig-nosed turtles have been found in most cities around the world. Due to the development of artificial growth technology, pig-nosed turtles are now very cheap. Interpretation: Regarding the translation of the name of pig-nosed turtle, Taiwan and Japan used to call it pig-nosed turtle from the beginning. However, when the land started, it was translated in various ways. There is already a popular way of calling it "two-clawed turtle". This translation is actually fallacious. , in fact, the word "turtle" does not exist in Latin at all. In the eyes of the ancient Romans, there were only land turtles and water turtles. The people who initially promoted the word turtle in mainland China made the mistake of using the translation word turtle because Chinese people complained inexplicably about the word turtle. This was a failed case of corporate transformation. Naturally, Japanese people play in many fields, and the translated names eventually dominate the Japanese customary names.
Water body conditions:
Living in water all day long, living normally when the water temperature is 25-31℃, never hibernate! Once dormant, he wakes up soon. Regarding the ph and kh values of water, the pig-nosed turtle is not a fish, does not have a lateral line, and is not very sensitive to the ph of water. If it is really true, you can refer to the Communist Party’s "Dianlingjin", ph6.0-7.5, kh hardness is neutral That’s it. However, you still have to be careful about harmful substances in the water. Pig-nosed turtles are not likely to have rotten skin. Generally, a filter is used. There are upper type, overflow type, and barrel type. They are all good choices. It is recommended to put a biochemical filter. , can cultivate a large number of nitrifying bacteria, which is very useful for controlling the concentration of nitrite and ammonium ions in the water. In an environment with sufficient dissolved oxygen, there will be no harmful gases such as hydrogen sulfide. If you want to lower the ph and kh values of the water, you may wish to follow the method of raising colorful giants and short snappers and put some grass mud pills and water softening resin.
