The Underwater World Electronic Poster introduces inhabitants of the seas and oceans. The poster shows around 30 members of the underwater world: a whale, dolphin, saw-fish, cuttlefish, squid and more. It has two modes: in one, by pressing the button next to a picture of an animal you"ll get concise information about it (for example, its features, size and hunting methods); you can also listen to the animal"s sounds, if audible to the human ear. The exam mode lets you check your own knowledge by answering questions. When an answer is correct, you"ll be praised and get another question. If you make a mistake, you"ll get two more tries before you"re given another question. The questions are all different: show a specific animal, find an animal by description (i.e., one that looks like an umbrella) or by the sound it emits. The poster has adjustable volume playback and automatic shut-off to preserve battery life and it can be hung on a wall or table. In Russian.
