The term "sea pig" usually refers to a pink, blob-like creature that lives on the ocean floor. However, there are other names for this unique animal. In scientific terms, sea pigs belong to the family of deep sea sea cucumbers known as Scotoplanes. These animals are sometimes referred to as "sea cucumbers" or "sea slugs". Other common names include "ocean pigs", "sea hogs" and "deep-sea potatoes". Sea pigs are harmless creatures that play an important role in the ocean ecosystem by filtering through sediment on the ocean floor and acting as a food source for other animals. Despite their unflattering appearance, sea pigs are a fascinating part of the underwater world.
