The rockhopper penguin's diet consists of krill and small crustaceans, which may include shrimp, crabs, lobsters or crayfish. [2] They also eat squid and myctophid fish. [2] [3] Rockhopper penguins consume more krill than they do fish; their diet changes during migration and as the seasons change. [3]

Chinstrap penguin. Penguins are birds in the family Spheniscidae in the monotypic order Sphenisciformes. [1] They inhabit high-productivity marine habitats, almost exclusively in the Southern Hemisphere; the only species to occur north of the Equator is the Galapagos penguin.
The type species was designated as the southern rockhopper penguin by George Robert Gray in 1840. [5] [6] Six extant species have been classically recognised, with the recent splitting of the rockhopper penguin increasing it to seven.
With the exception of the emperor penguin, where the male does it all, all penguins share the incubation duties. [63] These incubation shifts can last days and even weeks as one member of the pair feeds at sea. Penguins generally only lay one brood; the exception is the little penguin, which can raise two or three broods in a season. [64]

Most penguins feed on krill, fish, squid, and other forms of marine life caught while swimming underwater.

The rockhopper penguin (Eudyptes chrysocome) was split into three distinct subspecies in 1992; the southern, (E. c. chrysocome), eastern (E. c. filholi) and northern rockhopper penguin (E. c. moseleyi). The three subspecies are distinguished by differences in the length of the tassels of the crests, the size and colour of the fleshy margin of ...
