Why are tardigrades called water bear?

Tardigrades are commonly known as "water bears" due to their bear-like appearance when viewed under a microscope, characterized by their plump bodies and short, stubby limbs that resemble the legs of a bear. The name reflects their unique, slow-moving nature, as they often crawl through moist environments like a bear would. Additionally, their resilience and ability to survive extreme conditions add to their intriguing reputation, much like the formidable nature of a bear.
