Pardela de Navidad

The Christmas shearwater (Puffinus nativitatis) is a medium-sized seabird in the family Procellariidae, distributed across the tropical Pacific Ocean. It is entirely dark — sooty brown to black — with no contrasting pale underparts, distinguishing it from most other shearwaters. The species breeds on tropical Pacific island groups including the Hawaiian Islands, Johnston Atoll, the Phoenix Islands, the Line Islands, and several other central Pacific atolls, nesting in coral rubble, dense vegetation, or rock crevices. Like other shearwaters, it is a pelagic species that spends most of its life at sea, foraging for fish and squid in tropical Pacific waters. Christmas shearwaters fly with stiff, shearwater-style wing beats interspersed with gliding, following wave contours close to the ocean surface. Breeding colonies are vulnerable to introduced predators such as rats and cats, which have severely affected many Pacific seabird colonies. The species is generally considered stable within its extensive oceanic range, though individual island populations can be threatened by predator incursions. Conservation of Pacific island nesting sites through invasive mammal eradication programs has benefited this and many other tropical seabird species.

Delfín tonina

La especie de delfín más estudiada y reconocida, los delfines mulares habitan océanos cálidos y templados de todo el mundo, desde las aguas costeras poco profundas hasta el mar abierto. Altamente inteligentes con grandes cerebros en relación con el tamaño corporal, demuestran autoreconocimiento, comunicación compleja y aprendizaje social. Viven en sociedades fluidas de fisión-fusión y cooperan para arrear peces. Una especie indicadora clave de la salud del ecosistema marino.
