The White-bellied Go-away-birds and their alarm calls
Corythaixoides leucogaster (Cuculiformes - Musophagidae) is an African bird that has the peculiar common name of White-bellied Go-away-bird, because of their sentinel calls that (they say) sound like “Go Away” (listen here).
White-bellied Go-away-birds are also distinctive by the crest on the top of their head, along with its facial pattern. But the really interesting thing about this bird is that the Gunther’s dik-diks (Madoqua guentheri) responds to go-away bird alarm calls with anti predator behavior.
Recent studies suggest that alarm calls elicit responses not only from predators and conspecifics (organisms that belong to the same species) but also from other species (in this case, eavesdropping or cooperating heterospecifics).
When dik-diks hear the go-away bird alarm calls, they respond increasing alertness and adopting a protective behavior that include the immediate running, decreasing the time they spend foraging, increasing the looking rate, and increasing the time they spend stand looking.
Dik-diks neither produce complex alarm calls nor do they live socially, yet their extreme vulnerability to predators creates a strong selective force that may drive the evolution of associative learning abilities. This process is named associative learning evolution.

sci-universe:

Glaucus atlanticus, the blue dragon (also called sea swallow and blue angel), is a species of small-sized blue sea slug. This tiny animal spends its life floating upside-down on the surface of the Pacific, Atlantic, or Indian Ocean thanks to an air bubble which it swallows and keeps inside its belly, going wherever the currents and the wind take it.

This cute-looking creature is actually an aggressive predator that feeds on organisms much larger than itself, including the most venomous ones. It also can give you a poison sting when picking one up barehanded.
