Animals without tails

Here are some animals without tails:

1. Koalas: Koalas are a mammal that is unique to Australia. Although they are called "bears", they are not actually bears. Koalas are about 60-80 cm long and have a ball-like shape. They have no obvious tail.

2. Birds: Birds are a class of vertebrates with feathers and beaks. They usually have no obvious tail or only a very short tail. For example, penguins have almost no tail, and ornithischians have very short tails.

3. Snakes: Snakes are a class of reptiles without limbs. They have no obvious tail, but have a terminal part composed of many vertebrae, which is specially used to control movement and balance.

4. Whales: Whales are a type of marine mammals. Their tails are called "whale tails", which are actually fan-shaped and very strong muscle structures. However, the tails of some whales are not as obvious as the tails of ordinary mammals.

5. Angelfish: Angelfish are a type of tropical freshwater fish. They have beautiful colors and streamlined shapes, but they do not have obvious tails, only a small hole similar to an anus.

In short, koalas, birds, snakes, whales, and angelfish are some animals that do not have or have obvious tails.
