Sea Swine are aquatic creatures said to have been sighted by explorers in the early Modern Era. They are shown on many maps during this time, as well as being mentioned by Conrad Gesner, who is considered the founder of modern zoology. They are giant boar-like aquatic creatures with tusks. There are no modern sightings, although in the old times many explorers reported or drew these creatures. Some sightings of Sea Swine happened during the 1800s, but in the 1900s, no Sea Swine were reported. Sea Swine could have just been seals, sea lions, or walruses.
