The water droplet fish emoticon means that one is very sad, but it will soon pass, because the fish's memory is seven seconds.

The teardrop fish, also known as the sad fish or soft cryptic sculpin, bobber fish, due to a face of crying, known as "the world's saddest expression" of the fish. The teardrop fish lives off the coast of Australia and Tasmania, at depths of up to 1,200 meters, and is rarely found by humans because it is difficult to reach the fish's habitat.

Where the teardrop fish lives, fish fat (which helps fish stay afloat) is difficult to work effectively. To stay afloat, the water dropfish is covered in a gel-like substance that is slightly less dense than water, which helps it float easily from the bottom. The dropfish does not swim very fast underwater, which also prevents it from escaping in time when faced with deep-sea fishing.

Scientists have warned that the dropseed is threatened with extinction due to deep-sea fishing operations. Due to the massive increase in fishing activity, the dropfish is being caught along with other fish. Although the flesh of the dropfish itself is not fit for consumption, it is being sacrificed because it lives at the same depths as more flavorful sea creatures, such as crabs and lobsters.
