A male lion can weigh up to 250 kilograms, while a male gorilla can weigh up to 300 kilograms. Gorillas are also stronger than lions pound for pound. A gorilla's grip strength is about 1,000 pounds per square inch, while a lion's grip strength is only about 500 pounds per square inch. This means that a gorilla could hold a lion in its hand and crush its skull.
Gorillas are also more aggressive than lions. Lions are typically only aggressive when they are defending their territory or their young. Gorillas, on the other hand, are known to be aggressive even when they are not provoked. This is because gorillas are very territorial and they will often fight to the death to defend their territory.
