👉 The term "Dipseudopsinae" refers to a group of animals that primarily inhabit the water environment and are known for their ability to swim in both upright and inverted positions, often resembling human-like movements. This group includes aquatic mammals such as the pufferfish (Pseudopodophis), which can change its position from upright to inverted while swimming; some species also exhibit behaviors such as swimming backwards or upside down.
