Beryl is a colorless mineral made up of beryllium aluminium cyclosilicate. It forms hexagonal crystals that can be very large. When beryl has impurities, it can have a coloured tint or be opaque. Coloured beryl has different names - green beryl is called emerald, pale blue beryl is called aquamarine and pink beryl is called morganite.

Scientific name: family Potoroidae, genus Bettongia
A bettong is a small marsupial from Australia. Many people also call it a kangaroo rat because it looks a bit like a small rodent.
Bettongs hop on long back legs and have a pouch like other marsupials. They dig in the ground to find food, such as roots and insects. You can find them in dry areas and grasslands.
A group of quail is called a bevy or a covey.
