Садові вугрі розміром з сантиметр використовують хвіст для ковтання нор у піску

At just over a centimetre in diameter, Garden eels may be small compared to other species of eels, but what they lack in size they make up for in muscle. They use their strong, muscular tails to dig into the sandy seafloor then secrete a slimy mucus which acts like cement to keep its burrow from caving in. They spend the majority of their lives partially embedded in the sea floor, hiding fully in their holes when they see a predator. There can be hundreds of thousands of eels in just one colony.⁠
