Lanternfish in the context of Deep sea fish

The king penguin (Aptenodytes patagonicus) is the second largest species of penguin, smaller than but somewhat similar in appearance to the emperor penguin.

King penguins mainly eat lanternfish, squid, and krill. On foraging trips, king penguins repeatedly dive to over 100 metres (300 ft), and have been recorded at depths greater than 300 metres (1,000 ft). Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal, and the orca.

Hector's lanternfish (Lampanyctodes hectoris) is a lanternfish in the family Myctophidae, the only species in the genus Lampanyctodes. It is named after James Hector.

It is a widespread marine fish, known from shallow tropical waters in the south-eastern Atlantic, from the western Pacific off Australia and New Zealand, and from the eastern Pacific off Chile. It is one of the few species of lanternfishes to inhabit shallow waters, and in those waters it is one of the most abundant species of fish, and central to the food chain of the upper continental slope. The abundance is due to its high fecundity — it spawns multiple times in the winter so that the fry can take advantage of the spring bloom of krill.

The Merlucciidae, commonly called merluccid hakes /mərˈluːtʃɪd/, are a family of cod-like fish, containing two genera. They are the only member of the suborder Merlucciodei. They are native to cold water in the Atlantic and Pacific oceans, and typically are found at depths greater than 50 m (160 ft) in subtropical, temperate, sub-Arctic or sub-Antarctic regions.

These predatory fish are up to 1.55 m (5 ft 1 in) in length, though most only reach about half that length, inhabiting the waters of the continental shelf and upper continental slope, where they feed on small fish such as lanternfishes. Several species are important commercial fish, for example the North Pacific hake (Merluccius productus) that is fished off western North America.
