Pacific Seahorse
Hippocampus ingensAlso known as Giant Seahorse, Galapagos Seahorse
Pacific seahorses are the largest of their kind, blending seamlessly into kelp forests and rocky reefs along the Pacific coast using color-changing camouflage. These remarkable fish anchor themselves to marine vegetation with prehensile tails, waiting to ambush tiny passing crustaceans with their straw-like snouts. Like other syngnathids, males carry the developing eggs in a specialized brood pouch, giving birth to fully formed miniature offspring.

- Support conservation
- Never touch, capture, or disturb wild seahorses; observe them quietly from a respectful distance.
Responsible observation
- Look closely: Search among kelp holdfasts, gorgonians, and black corals where they anchor themselves.
- Maintain distance: Avoid touching or crowding them, as stress can disrupt their delicate feeding and mating behaviors.
- Use ambient light: Avoid using strong flash photography, which can startle and disorient these sensitive fish.
