The cucumber (Cucumis sativus) is a widely grown plant in the family Cucurbitaceae. This family also includes squash. A cucumber looks similar to a zucchini (British English: courgette).
To a botanist, cucumbers are biologically fruits even if they are commonly thought of as vegetables: that is their value as a food. They can be cooked, eaten raw, or pickled. Some people hollow out the cucumber and fill it with other food, like tomatoes or feta cheese.
