Hello Ladies & Gentlemen! In collaboration with our Social Media Volunteers, we designed a series of 13 informational graphics on the subject of Dolphins! Dolphins are a group of cetaceans belonging to the families Delphinidae, Platanistidae, Iniidae, Pontoporiidae, & Lipotidae families. Dolphins are known for their intelligence, playfulness, agility, & streamlined physiques. The first graphic in this series discusses the anatomy of a dolphin, including their ability to use echolocation. “Dolphins may look like fish, but their bodies are built very differently. Inside, they have lungs instead of gills, which means they must swim to the surface to breathe air through their blowhole. Their bodies are streamlined, with smooth skin and a layer of blubber that helps them stay warm in the ocean. This shape allows them to glide through the water with very little resistance. One of the most important structures inside a dolphin is the melon, a rounded organ in the forehead. The melon helps focus sound waves for echolocation, which dolphins use to “see” underwater. They also have strong muscles along their spine and tail that power their flukes, giving them the speed and agility they’re known for. Dolphins have a simple stomach for storing food and a second chamber for breaking it down. Their teeth are shaped like small cones, perfect for grabbing slippery fish and squid. Instead of chewing, dolphins swallow their food whole. Their internal organs are arranged to help them stay balanced and stable as they swim.”
