Their color varies from brown to bright orange, often matching the surroundings. Unlike tropical species, they have a slightly more angular coronet on top of the head.

4. Are there any other seahorse species that might appear in Washington?
Occasional reports of the lined seahorse (Hippocampus erectus) exist, but these are likely aquarium releases. No other species have confirmed wild populations. If you see a seahorse with a long snout and a curled tail, it’s almost certainly a Pacific seahorse. For detailed species breakdowns, see ourtypes of seahorses page.

5. What is the best way to identify a seahorse in the field?
Look for a horse-like head, a prehensile tail, and a body encased in bony rings. Pacific seahorses have 11 trunk rings and 35-38 tail rings. They hold onto eelgrass with their tail and swim upright. Use a snorkel mask in calm, clear water to spot them.This seahorse field guideincludes a ring-count chart.
6. Why are seahorses so rarely seen in Washington compared to other marine life?
Seahorses are masters of camouflage and blend perfectly with eelgrass. Their populations are naturally sparse at the northern edge of their range. Water temperature and habitat loss also limit their numbers. For context on Washington’s marine biodiversity, check ourWashington wildlife overview.
