Video of a leopard seal swimming and looking for emperor penguins in Antarctica, from Watanabe et al., Activity Time Budget during Foraging Trips of Emperor Penguins A leopard seal attacking an emperor penguin. The only natural predator of leopard seals is the orca. [4] The seal's canine teeth are up to 2.5 cm (1 in) long. [35]
Gentoo penguins can reach a length of 70 to 90 cm (28 to 35 in), [19] [20] making them the third-largest species of penguin after the emperor penguin and the king penguin. Males have a maximum weight around 8.5 kg (19 lb) just before moulting and a minimum weight of about 4.9 kg (11 lb) just before mating.
The chinstrap penguin's tightly packed feathers provide a waterproof coat, enabling it to swim in freezing waters. Additionally, thick blubber deposits and intricate blood vessels in the flippers and legs assist in the preservation of heat. [6] The main predator of the chinstrap penguin at sea is the leopard seal (Hydrurga leptonyx). Every year ...
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). [2] Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal, and the orca.
[97] [98] The leopard seal, a prolific predator of penguins, is known to violently shake its prey to death. [99] Complex serrations in the teeth of filter-feeding species, such as crabeater seals, allow water to leak out as they swallow their planktonic food. [85]
Emperor penguin attacked by a leopard seal Giant petrel and emperor penguin chicks. The emperor penguin's predators include birds and aquatic mammals. Southern giant petrels (Macronectes giganteus) are the predominant land predator of chicks, responsible for over one-third of chick deaths in some colonies; they also scavenge dead penguins.
Predators and Threats. Emperor penguins are preyed upon by a number of large, marine carnivores, but their exact predators vary between geographic locations. ... Leopard seals prey on adult ...
Thus, the crabeater seal, with the most specialized sieve-like dental features, is the only seal that feeds predominantly on Antarctic krill, while the leopard seal is the only seal which actively preys on other seals and penguins, while still retaining the ability to filter-feed on krill. [4]
