A giant seahorse requires training before it can bear a rider in combat. To be trained, a giant seahorse must have a friendly attitude toward the trainer. Training a seahorse as an aquatic mount requires six weeks of work and a successful DC 15 Wisdom (Animal Handling) check. Riding a seahorse requires an exotic saddle. A seahorse can fight while carrying a rider. Seahorse eggs are worth 2,000 gp apiece on the open market, while young are worth 4,000 gp each. Professional trainers charge 1,000 gp to rear or train a giant seahorse.
