At present, the domestic supply of domestic snapping turtles and turtle seedlings is relatively scarce. Some profit-seeking speculators have used the vast majority of farmers who have never seen small snapping turtles. They are ignorant of the shape characteristics of small snapping turtles, but are anxious to purchase them. For the “null†used for breeding, other turtles that are a bit similar in appearance or similar in living habits are pretending to be small snapping turtles, which are fraudulent purchasers and sold at high prices. Recently, the author's two friends went to a company to buy a plant. When they saw the real thing, they suddenly realized that what they sold was only a semi-submerged turtle that had a similar shape to a small snapping turtle. Small Snapping Turtle is a species in the Snapping Turtle family, referred to as Snapping Turtle, alias Crocodile Turtle, Turtle Tortoise, American Snake Tortoise, etc. It originates in rivers and lakes in North and Central America, and is mainly eaten as meat and belongs to aquatic species. My country was introduced from the United States in 1996 and it has now been successfully farmed. Due to the fast growth rate of small snapping turtles, individuals gain about 1 kilogram a year and grow up to a maximum of 10 kilograms; meat production rate is more than 85%, which is obviously higher than other turtle species; spawning is more, breeding is faster, and eggs are laid one year. 2-3 batches, each batch of 20-30 egg-laying; strong disease resistance, easy feeding, coupled with its delicious meat, nutrient-rich, so it has become China's farmers are competing species ideal breeding. Small snapping turtles feature prominently. As long as they are observed carefully, they can be identified and will not be deceived by unscrupulous merchants. Adult turtles are brown or brown in color, mainly brown, and hatchlings are approximately black. The carapace is broad-circle with a length-to-width ratio of approximately 4:3. The plastron is very small and the area is only about 1/3 of the carapace. The shape and shape of the X-shaped figure are relatively rare in turtles. After the head of a small snapping turtle head is fully extended, the length from the beginning to the end can be roughly divided into three equal parts, that is, the head, the body, and the tail each occupy 1/1. 3; The head can not be fully retracted, the tail tail is thick and the tail is thin, and from coarse to fine sharp reduction; faster and thicker limbs, strong fingernail bending, there are moles between the toes, crawling, the four limbs propped up, head Stretching slightly faster than other turtle species; after the turtle's body has fallen into the water, it will surface for a while and breathe it with its nostrils; when the adult snapping turtle encounters a dangerous situation, it will quickly lift its head and glared at it. Open a big mouth, give off a gas, and warn the other party with a squawk. If the warning is invalid, the head will bite, and the action will be quick and swift. Once it bites, it will remain for a long time. When the melon wall escapes, the limbs will climb and the hind limbs will escape. Standing upright and assisting with tail support, the climbing ability is stronger. The small snapping turtle has a full and well-developed muscle. It is very good for the leg. If you weigh it with your hand, the body is heavy, giving you a sense of “hand pressingâ€. This is also incomparable to other species of turtles. The distinctive feature of the small snapping turtle is its distinctive back and tail. There are three well-arranged obvious scutellums on the carapace, two rows of clearly visible spinous processes on each side of the middle column, the prominent point is located at the junction of the two scutellums, and radiates many rays into the film; The edge, with the tail as the boundary, has four reciprocal symmetrical jagged pieces on the left and right sides. The teeth are blunt and not as sharp as a turtle. The central tail has a prominently protruding skeleton, which is arranged from high to low to the tip of the tail except for the first one. It resembles the back of a crocodile and the cocoon on its tail. The crocodile turtle is named after this.
