Indohyus was not a direct ancestor of whales, but they diverged from the whale's evolutionary line after gaining some traits of whales, such as their unique inner ear and thick bones. Indohyus had a long thick tail. Indohyus was actually a vegetarian and was only the size of a cat. Comparing Indohyus' size to modern whales' size shows quite the difference in sizes.
Because Indohyus was herbivorous, this mammal's underwater activity was mostly based on Indohyus diving into the water to escape predators.
