Mythological creatures are very interesting. Dragons, unicorns, and more are spoken of in the Bible, but not in the traditional sense. The King James Version translated many unknown Hebrew words into exotic English words. The Bible mentions dragons in Psalm 148:7, Isaiah 43:20, and Micah 1:8, where the Hebrew word means some kind of very large or hideous creature. Dragons are also mentioned in Revelation 12 and 20. In Revelation, the dragon refers to Satan.

Satyrs are mentioned in the Bible (Isaiah 13:21; 34:14), but they are not the same as the satyrs in mythology. The more accurate translation for the Hebrew word, sa'iyr, is a male goat, not a half-man, half-goat creature. The KJV translated the Hebrew word, re'em, to mean unicorn; however, a more accurate translation is the word auroch, a now-extinct ancestor of cows.

The cockatrice is a mythological monster that is half-rooster and half-snake, with the ability to turn people into stone at a glance. It is mentioned in Deuteronomy 33:17, Psalm 22:21, and Isaiah 34. A more accurate translation of the Hebrew word tsepha' is "poisonous serpent or viper," not a half-rooster, half-snake creature.

The behemoth is said to be a massive creature with a tail like a cedar tree (Job 40:15–24). Many people believe the behemoth is a hippo or an elephant, but this doesn't match the description of the creature's tail. Many biblical scholars think the behemoth is either an apatosaurus or diplodocus dinosaur. The leviathan is also believed to be a dinosaur that lives in the sea (Isaiah 27:1; Psalm 74:14; 104:24–30). It is often referred to as a sea monster (Job 3:8).
