Penguins are birds of the ocean, spending up to 75 percent of their lives in the water. Some penguins, like the fiordland and rockhopper, have even been found with barnacles growing on their feathers! Much of what seems odd about penguins is due to the fact that they spend so much time in the water. Swimming is what penguins do best.

Highly adapted for life in the ocean water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. [5]

2020年2月24日 · Just by looking at a penguin, it is clear to see that their bodies have been specially adapted for swimming. They have developed a streamlined body shape that reduces drag when they are in the water; a shape which has also been adopted by fish and marine mammals. Their wings (called “flippers” on penguins) and feet also serve a purpose.

2021年4月8日 · Penguins are flightless birds with flippers instead of wings. Their bodies are adapted for swimming and diving in the water, with some species able to reach speeds up to 15 miles per hour....

Penguins use their streamlined bodies and strong flippers to swim rapidly through the water, enabling them to close in on their prey with precision and speed. They are skilled predators, using their agility and hydrodynamic features to their advantage, making them formidable hunters in their marine environment.

2021年11月3日 · In this study, we recorded the forward and horizontal swimming of gentoo penguins (Pygoscelis papua) at an aquarium with multiple underwater action cameras and then performed a 3D motion analysis. We also conducted a series of water tunnel experiments with a 3D printed rigid wing to obtain lift and drag coefficients in the gliding configuration.

2023年10月4日 · Gentoo penguins cut through water with shocking speed. These Antarctic birds are only about the size of human toddlers. Yet they can swim up to 35.4 kilometers (22 miles) per hour. That makes them the fastest swimming birds in the world. Now, scientists think they’ve figured out how they do it.

2019年11月22日 · Penguins use their well developed breast and wing muscles to swim through the dense water. The penguin's blood, specifically its hemoglobin, is specially adapted to circulate additional amounts of oxygen for use during swimming.
