How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/biology/133-finding-nemo-dory-turtles-and-the-reef/). - [0](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/0/) — Dory, Crush, Squirt, Bloat and Mr Ray are all based on real sea animals, but the film changes some things for the story. - [1](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/1/) — Real blue tangs do not forget everything: most fish remember things for weeks or months, so Dory's memory is a story idea, not fish science. - [2](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/2/) — Imagine a beach at night: tiny turtles pop out of the sand and race towards the brightest thing they can see, which is normally the moonlit sea; that is why beach towns switch off their lights in hatching season. - [3](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/3/) — Sea turtles cannot pull their heads into their shells like Squirt does, and to a hungry turtle a floating plastic bag looks just like a jellyfish. - [4](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/4/) — Adult blue tangs are blue with black markings and a yellow tail, but young ones are bright yellow, and blue tangs can turn paler at night or when scared. - [5](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/5/) — A blue tang has a sharp spine like a little knife near its tail that it can flick out to defend itself. - [6](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/6/) — Blue tangs often feed in groups, grazing algae off coral and rocks, which helps them push past fish guarding their own algae patches and stops algae smothering the coral. - [7](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/7/) — Green sea turtles probably live 80 years or more, but 150 years is more than scientists know of, and they may not have babies until they are 20 to 40 years old. - [8](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/8/) — Sea turtles have lived in the oceans since the time of the dinosaurs. - [9](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/9/) — The East Australian Current is real: it carries warm water south along the coast of Australia, and turtles and fish use currents to travel with less effort. - [10](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/10/) — Turtle hatchlings climb out of their nests at night and head for the brightest horizon, usually the sea; street and hotel lights can lead them the wrong way. - [11](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/11/) — Sea turtles cannot pull their heads or flippers into their shells, because their streamlined swimming shells have no room inside. - [12](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/12/) — Sea turtles eat jellyfish, and floating plastic bags look like jellyfish, so turtles sometimes swallow plastic, which can block their stomachs. - [13](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/13/) — Leatherback turtles eat huge amounts of jellyfish, and their throats are lined with spikes that keep the slippery food from sliding back out. - [14](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/14/) — Jellyfish sting with tiny harpoon cells in their tentacles that fire when touched, and they have no brain, heart or bones and are mostly water. - [15](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/15/) — Pufferfish gulp water and swell into a spiky ball when scared, which makes them hard to swallow, and many contain a strong poison, so in Japan only specially trained cooks may prepare them. - [16](https://md.mova.elamur.ai/free/en/corpora/school/biology/133-finding-nemo-dory-turtles-and-the-reef/16/) — Spotted eagle rays flap wing-like fins to fly through the water and sometimes leap out of it; rays are flat relatives of sharks with skeletons of cartilage (the bendy stuff in your ear), not bone. - ← previous: [Finding Nemo: real clownfish and sea anemones](https://md.mova.elamur.ai/free/en/corpora/school/biology/132-finding-nemo-real-clownfish-and-anemones/) - next →: [Finding Nemo: real sharks, anglerfish, pelicans and gulls](https://md.mova.elamur.ai/free/en/corpora/school/biology/134-finding-nemo-real-sharks-anglerfish-and-seabirds/) - ↑ back to [Biology](https://md.mova.elamur.ai/free/en/corpora/school/biology/)
