Silonia childreni is a freshwater fish with a long silvery body. It lives in the rivers of India and Bangladesh and feeds on small animals.
Children's silurus is distinguished by its very long anal fin from other catfishes. It helps maintain balance in the river ecosystem by eating small animals and serving as food for large predators.
Quick pursuit and swallowing prey whole.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
