African Lungfish: Anatomy, Habitat, and Unique Survival Adaptations #92753 (License: Personal Use)

This illustration depicts the African lungfish (Protopterus annectens), a freshwater species native to slow-moving rivers and swamps across sub-Saharan Africa. It features a long, eel-like body covered in mottled olive-brown and dark patches, with paired lobed fins and a continuous dorsal-caudal-anal fin fold. Notably, it possesses both gills and functional lungs, allowing it to breathe air and survive months out of water during dry seasons by burrowing into mud and entering estivation.

Used on educational wildlife pages, biology textbooks, museum exhibits, or conservation sites to illustrate anatomical features and adaptive traits of sarcopterygian fish; matches user intent for learning about evolutionary intermediates, aquatic survival strategies, or preparing school reports.
