Sea goblins range in size from 2 meters to over 30 meters and come in a variety of forms, including those that are simply black, those with glowing red eyes, those with hair and beaks, and those that are slimy. Their ecology is shrouded in mystery, but this hand-drawn animation depicts the life of a sea goblin from birth to death, hypothesizing that the differences in size and appearance are the process of metamorphosis of a single individual. This is a documentary on the ecology of sea goblins that no one has yet seen. (Source: Hiroshima Animation Season)
