What do you call agroups of tigers and how fast can they run?

A group of tigers is called an "ambush" or a "streak". Tigers are powerful and remarkably fast predators. Different tiger species can reach different maximum speeds. Here are the top speeds recorded for various tiger species:

1. Bengal Tiger:

- Maximum speed: Up to 49-55 km/h (30-34 mph)

2. Siberian (Amur) Tiger:

- Maximum speed: Up to 50-60 km/h (31-37 mph)

3. Indochinese Tiger:

- Maximum speed: Up to 49-55 km/h (30-34 mph)

4. Malayan Tiger:

- Maximum speed: Up to 45-50 km/h (28-31 mph)

5. Sumatran Tiger:

- Maximum speed: Up to 40-50 km/h (25-31 mph)

These speeds vary depending on several factors such as the tiger's age, size, and the terrain they are running on. Tigers are known for their short bursts of speed over short distances, and they typically hunt by ambushing their prey rather than relying on sustained chases.
