Okinawa is home to many precious creatures. Appearing after sunset is the Okinawa Warty Newt. It is a designated natural monument of Okinawa Prefecture. Despite its cute appearance, it is a natural monument and must not be touched. Of course, moving, keeping, or selling them is also illegal. These regulations are in place to protect the Okinawa Warty Newt. If you find one, please treat it gently and respectfully. However, these Okinawa Warty Newts are preyed upon by invasive species! They are swallowed whole by species such as the Taiwanese pit viper and the Okinawa bullfrog… The spotted crayfish (mystery crayfish) even eats the eggs and larvae of the Okinawa Warty Newt. If this species invades the Okinawa Warty Newt's habitat, it will be a serious problem! This clearly explains why it is regulated under the Invasive Alien Species Act. Catching invasive species before they spread is crucial! From a conservation standpoint, we cannot reveal the Okinawa Warty Newt's habitat, but we hope that this conveys the importance of controlling the spotted crayfish that have entered Naha City's Ameku Churamachi Park. Laws to protect native species Laws to properly manage invasive species First, let's develop the ability to identify familiar organisms! ●Ponds are a mirror of the community If garbage and living creatures are dumped in them, the pond will be filled in... If they are carefully and properly managed, they can recover! Of course, it's important to maintain an environment that can be reset at any time. It's important to cut back lotus plants before they wither in winter. Withered leaves accumulate and the water becomes polluted. Use ponds responsibly! 【YouTube】 No moving or selling!
