The pygmy seahorse is one of the smallest seahorse species. Its length does not exceed 2.5 centimeters. It lives among seagrass in warm coastal waters.
The pygmy seahorse differs from other species by its very small size and short lifespan. It is important for nature as part of the food chain in seagrass beds and as a predator of small crustaceans.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
