Is there a limit to how big animals can grow?

Joshua A. Krish poses this question in his article in Live Science (March 2023) and he says that there is a limit – animals can’t grow indefinitely.

The largest land animal is the African Elephant (Loxodonta africana) which is a mammal that reaches 250 centimetres (8 feet 4 inches) tall and 750 centimetres (25 feet) long, weighing about 6 metric tons (7 tons). It is not a meat-eating carnivore. It is an herbivore and eats grass, trees, bushes, fruit, and bark.
