A couple in Thailand kept hearing a strange noise outside at night, and they recently were able to discover where it was coming from.

In a video shared on TikTok in July under the username @dollylolly4, the couple explains that the sound they kept hearing at night was coming from a small lizard known as a Tokay gecko.

"I love learning about new species!!! We've been hearing this sound and could never find where it was coming from! This is the sound of the Tokay gecko mating call, we've seen him a few times breaking into our kitchen at night," a caption says.

Tokay geckos are greenish gray lizard with gray and orange-brown spots covering body. They are characterized by a slender body with a large head, prominent eyes, and broad fleshy toes with inner folds, as explained by United Parks and Resorts.

These lizard can live up to 20 years, eating insects, baby birds, and small mammals such as nesting mice. They are usually found around Southeast Asia and the Malayan Isles; northeast China, Indonesia, and Thailand, where they like to hide behind bushes and trees, and on or around rocks.

"Nearly all geckos have a voice, ranging from a small squeak to the deafening whistles of the African whistling gecko," the website says.

When they feel threatened enough, these geckoes can inflict severe bites, and when caught in an altercation, they have the ability to cast off its tail in defense and later regenerate a new one.

"The cast off part will continue to move for several minutes, giving the gecko time to escape. It takes approximately three weeks for these geckoes to completely regenerate a new tail although it is usually never as long as the original tail," the website added.

The video quickly went viral on social media, getting viewers from across TikTok. It has so far received over105,300 views and 1970 likes on the platform.

One user, Ilse, commented: "Those are feisty!! They bite really hard."

Crypt said: "Sound like a duck."

Another user, Yonks, added: "So cute!"
