Hipopótamo Anfibio

El mamífero terrestre grande más peligroso de África, el hipopótamo común (Hippopotamus amphibius) puede alcanzar los 3.200 kg y habita ríos, lagos y humedales del África subsahariana. Semiacuático, pasa hasta 16 horas diarias sumergido para mantenerse fresco y pace en tierra por la noche. Pese a su apariencia tranquila, es extremadamente agresivo y territorial, responsable de cientos de muertes humanas cada año. Clasificado como Vulnerable, sus poblaciones están amenazadas por la pérdida de hábitat y la caza furtiva de colmillos de marfil.
