Periophthalmus chrysospilos is a fish from the goby family that can breathe air and move on land using its pectoral fins. It lives in mangrove thickets and often ventures onto muddy shallows.
This species differs from other mudskippers by golden spots on its body and head. It is important for nature because it mixes mud, controls the population of small animals, and serves as food for birds and other predators.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
