Like scaly sumo wrestlers, these male monitor lizards are squaring off over food and females. They might brawl for 45 minutes before a victor emerges.
When out on the hunt in its tropical domain, the monitor lizard likes to fly solo.
His forked tongue helps him sniff out decaying fish, flesh...and females.
But when love is in the air, potential suitors come out of the woodwork.
And with this quick-tempered lizard, that means instant competition.
These scaly battles can last for up to 45 minutes.
This isn't a fight to the death, but rather a display of dominance and strength, a heavyweight sumo match with claws...where the loser gets pinned underwater.
The triumphant male gets the girl, but he better watch out.
Female monitors are just as ready to scrap-they'll fight their mates for food.
When it comes to survival amongst these lizards, there's no such thing as one big, happy family.
