Intex Large Inflatable Whale

Product Information

Barnacles are small sea creatures related to crabs and lobsters. They're one of Earth's oldest species, and you can tell just by looking at their simple design. Have you ever wondered about those tiny shell-like hitchhikers on a whale's skin? Barnacles are small ocean travelers that latch onto whales, munching on plankton as they go. But why do these massive whales let them hang around? Given their size, it's likely that whales barely notice these tiny lodgers. Barnacles often latch onto baleen whales, and you'll usually find a specific type, called Cryptolepas rhachianecti, covering gray whales.

Taking carcasses to landfill is generally seen as the optimal disposal method, with around a third of all beached whales being disposed of in this manner in the US. Scientists aren’t sure exactly how barnacles attach themselves to whales, but most experts believe they attach themselves within the first couple of weeks after their birth when they are still very small. When whales move towards the bottom of the sea to feed on schools of fish, they slow down, allowing the free-floating barnacle larvae to hitch a ride.

Sponsorship & Advertising Policy Like many other sea creatures, barnacles are unique and minimally understood. Because they are hard to locate and examine, most of what we know about barnacles comes from observing them as whales migrate.As they grow, barnacles develop tough, pointed shells to protect their soft bodies. These shells dig into the whale's skin, ensuring a secure grip. Inside, they have tube-shaped structures that help them anchor firmly to the whale. According to the team's measurements, Anderson says that the shear force experienced by an average-sized remora in the wake behind the blow hole of a whale swimming at the casual speed of 1.5 m/s can be as low as 0.02 Newtons, half the force of drag in the free stream above. However, Anderson notes that the average remora's suction force of 11-17 Newtons is more than a match for even the most intense parking spot on the whale, its tail, where the remora experiences roughly 0.14 Newtons of shear force. And though the forces are greater, the same is true even for large remora riding on whales swimming at much higher speeds. T​he barnacles found on whales are a type of crustacean that attach themselves to a surface and stay there until they die or are brushed off. The barnacles you see on whales belong to a specific species known as acorn barnacles. A single whale may have up to 1,000 pounds of barnacles living on it at a time.

By attaching themselves to whales, who regularly travel to areas with plenty of food to eat, the barnacles have unlimited access to food. Most barnacles attach themselves on the whale’s head so that they can easily filter the food that the whale spills out of its mouth as it eats. They are guaranteed plenty of fresh food and water in this prime location. Incineration has also been used to safely dispose of remains, but it can be difficult to conduct on a large carcass.Barnacles generally don't harm whales, so there's no need to remove them. However, if there are too many, they might irritate the whale skin. When barnacles dig in, they can sometimes scrape off the top layer of the whale's skin. When a whale swims through plankton-rich waters, the barnacle gets a free meal. It simply stretches out its filtering arm and catches the floating plankton. As the host whale moves, the barnacle enjoys a constant buffet.
