The Hippocampus is one of several species in Valley of Unicorns. Hippocampi have multiple adult lineart poses, referred to as V1 and V2. However, all existing hippocampus colors at this point are only available in one of the two poses.
Hippocampi are recognizable by their fishlike bodies and flowing fins. They are currently the only species on the site to not have hooves, which was previously a requirement for species to be implemented. They are also the only unbreedable horse species that can be either male or female.
Below is the complete list of Hippocampi currently on VoU.
