Las focas y los leones marinos tienen un aspecto similar y algunas veces es complicado saber cuál es cuál. Ambos mamíferos marinos nadan con aletas y pueden encontrarse en océanos alrededor del mundo. Uno tiene orejas visibles, mientras que las orejas del otro no son externas. Uno atraviesa el agua utilizando sus aletas traseras, mientras que el otro usa sus aletas frontales para nadar. Ya sobre tierra, uno rebota hacia sus alrededores, mientras que el otro puede “caminar” sobre sus aletas.
¿Qué tienen en común y en qué se diferencian los cangrejos y las langostas? Aunque ambos animales viven en el océano, uno prefiere nadar y el otro caminar. Uno puede ser encontrado en pozas costeras y el otro en alta mar. Ambos tienen esqueletos en la parte externa de sus cuerpos. ¡Hay mucho más sobre estos animales además de ser un buen alimento para nosotros!

Most of Earth is covered by oceans and seas that are home to an amazing variety of animals. Some have adapted to life in the cold, dark aphotic zone.
