Octopuses: Acrobats of the Sea
LET'S LEARN ABOUT THE OCTOPUS | |
Octopuses are sea animals famous for their rounded bodies, bulging eyes, and eight appendages. They live in a all the world's oceans but are especially abundant in warm, tropical waters. Octopuses, like their cousin the squid, are often considered "monsters of the deep," though some species occupy relatively shallow waters. Most stay along the ocean's floor, although some are pelagic, which means they live near the water's surface. Other octopus species live in deep, dark waters, rising from below at dawn and dusk to search for food. Crabs, shrimps, and lobsters rank among their favorite foods, though some can attack larger prey, like sharks. Octopuses typically drop down on their prey from above and, using powerful suctions that line their arms, pull the animal into their mouth. The octopus performs its famous backward swim by blasting water through a muscular tube on the body called a siphon. They also crawl along the ocean's floor, tucking their arms into small openings to search for food. Seals, whales, and large fish are their predators. |

If threatened, they'll shoot an inky fluid that darkens the water, confusing the aggressor. Another form of protection is its ability to change colors to gray, brown, pink, blue, or green to blend in with its surroundings. They may also change color as a way to communicate with other octopuses. They're solitary creatures that live in dens built from rocks, which it moves into place using its powerful arms. Octopuses sometimes even fashion a rock "door" for their den that pulls closed when the octopus is safely inside. Although they live and breathe underwater, the land is no obstacle for this extraordinary species. Most species can live out of water for up to an hour using its muscular mantle cavity to draw air into the pallial cavity, which is absorbed into the gill structure, which then extracts oxygen and releases carbon dioxide. They literally absorb oxygen through its skin, which can allow it to hunt on land if needed. How cool is that?!? | |
Octopuses live relatively short lives with some species living for as little as six months, and others that may live for as much as five years. Their lives are limited by reproduction, which causes the breakdown of cellular function without repair or replacement. This happens to males after mating, and to females when they lay their eggs. Females will spend their time aerating and protecting their eggs until they hatch, refusing to eat throughout the process. They quickly weaken until they die. However, the Pacific Striped Octopus is an exception as they can reproduce more than once in their life. They're also HIGHLY intelligent with the ability to solve mazes and problem-solving experiments. they can store both short and long-term memory and able to do so without learning from a parent. They also have the ability to break out of aquariums, open bottles, play with toys, and more. |
