Residents of the Taiwanese city of Keelung found seven blue dragons on the shore of a fishing pier. These are not – as the name suggests – flying, fire-breathing creatures, but sea snails. They were last seen here 10 years ago.
On Tuesday, November 21, residents of the town of Keelung were surprised to find strange creatures with an intense blue color on the shore of the Changtanli Fishing Harbor. They were blue dragons, or sea snails. Their unique appearance attracted the attention of many onlookers who eagerly took photos of them. Local media reported that seven individuals were found Glaucus atlanticus.
Poisonous blue dragons
Blue dragons have appeared sporadically in Taiwan since 2010, when they were first sighted. They re-emerged in 2012 on Liuqui, a coral island located 13 kilometers from Taiwan. They were last seen at the Keelung fishing pier in 2013.
blue dragon (Glaucus atlanticus) is also called “sea swallow” or “blue angel”. It is a species of sea snail from the order Nudibranchia. These creatures typically reach up to three centimeters in length. They are found in temperate and tropical waters of the Atlantic, Pacific and Indian Oceans. They have an intense blue color, which is a warning signal against predators. This species contains toxic chemicals.
These sea creatures are known not only for their unique color, but also for the fact that they float upside down on the surface of the water,
Glaucus atlanticus are predatory, feeding on organisms larger than themselves and venomous, such as Portuguese sailors (Physalia physalis). The venom of the Portuguese sailor is not poisonous to the blue dragon, which stores it at the ends of its leg protrusions, providing it with a deadly weapon against its victims. These small snails can also be dangerous to humans – when touched, they can release venom that hurts.
