Many people may not distinguish a soft-shelled turtle from a regular turtle! Additionally, it often carries the frightening image of never letting go once it bites.

![](/logo.webp)
Class: Reptilia, Order: Testudines, Family: Trionychidae, Genus: Trionyx
Shell length: 25–30 cm (both male and female), Weight: up to about 7 kg
In Japan, it is found in Honshu, Shikoku, Kyushu, Okinawa Island, Ishigaki Island, Iriomote Island, and Yonaguni Island.
Outside Japan, it is said to be distributed in China, the Korean Peninsula, southeastern Siberia, Taiwan, and northern Vietnam.
The back shell part is very flat and covered with soft skin without any scutes.
The tip of its nose protrudes, and it can often be seen hiding in the sand or mud at the bottom of the water, with only its nose sticking out.
Soft-shelled turtles also bask in the sun, so you might see them sunbathing on their shells near rivers.
They are very timid creatures and are highly sensitive to noises, quickly diving back into the water when approached.
They mate from April to June and lay eggs from June to August. The eggs are spherical, about 2 cm in size, and each mating can result in laying 10 to 40 eggs.

What is the origin of the name 'Soft-shelled Turtle'?
There are various theories about the origin of the name 'soft-shelled turtle'. This turtle is very timid and quickly dives into the water when sensing the presence of other creatures.
The name is believed to have originated from the behavior of diving into the water so swiftly, often described as 'diving in like a soft-shelled turtle'.
Previously, it was also known as 'Drogame', but it has been called 'soft-shelled turtle' since the Edo period.

Why do soft-shelled turtles live there?
Soft-shelled turtles are not only found in Japan but also inhabit areas in China and the Korean Peninsula.
The exact natural distribution of soft-shelled turtles is not well understood. While there are native species, it is thought that many are either escapees from captivity or have been introduced from abroad, leading to potential hybridization.
Furthermore, the soft-shelled turtles in the southwestern islands are considered to have been artificially introduced from China, and studies are still being conducted to trace their origins.

In captivity, they are fed commercially available pellet food, but also consume mealworms, bloodworms, and snails.

Do soft-shelled turtles not let go once they bite?
There is a saying that a soft-shelled turtle will not let go until it thunders. In reality, while soft-shelled turtles can clamp down hard and not easily release their bite, it's not true that they wait for thunder to let go. The strong jaw can pull back into the shell while biting, so if you ever get bitten, calmly place the turtle back into the water without panicking.

What is the difference between soft-shelled turtles and other turtles?
Many people find it difficult to distinguish between soft-shelled turtles and other turtles. The main difference is that the shell of a soft-shelled turtle is softer and flatter compared to other turtles.
Additionally, soft-shelled turtles have visible stripes on their necks, three toes (compared to five in other turtles), and a thicker, longer tail.

Why are soft-shelled turtles expensive?
Soft-shelled turtles are known as a luxury food ingredient, but they can also be seen swimming in rivers.
The high price is attributed to the variability in taste between individuals, susceptibility to disease, and the common use of farmed turtles. Farming soft-shelled turtles is not only limited in scale but also takes two to three years before they are suitable for consumption. Additionally, culinary preparation of soft-shelled turtles requires specialized skills, contributing to the high cost of dishes.

Can soft-shelled turtles be kept as pets?
It is possible to keep soft-shelled turtles in a home setting. They can eat commercial turtle food as well as mealworms and snails, making feeding relatively simple.
