The converse of this is the nasty neighbour effect in which a territory-holder shows heightened aggression toward neighbouring territory-holders but unaffected aggression to unfamiliar animals or distant territory-holders. These contrasting strategies depend on which intruder (familiar or unfamiliar) poses the greatest threat to the resident ...
This puts them well over the second tallest animal, the African Bush Elephant at 10 to 13 feet. Not only are they tall, but giraffes are massive animals, weighing between 1,750 and 2,800 pounds.
The state of New York considers attending an animal fight to be merely a violation, which ultimately leads to a fine. States surrounding New York like New Jersey and Connecticut passed a bill, stated that attendance at an animal fight is indeed a felony charge.

The Gila Monster (Heloderma suspectum) for example, express bright orange splotches during territorial conflict to warn competitors that they are poisonous, and thus assert their dominance over a territory.
