African elephant

The largest land animal on Earth, African elephants can reach 7,000 kg and inhabit sub-Saharan savannas, forests, and wetlands. Highly intelligent with complex social structures led by matriarchs, they communicate through infrasound, rumbles, and touch. As ecosystem engineers, they shape habitats by uprooting trees, digging waterholes, and dispersing seeds. Vulnerable, with populations declining due to ivory poaching and habitat loss.
