Interesting. Maybe they'd be used to intimidate predators too, like how the Blue-Tongued Skink flashes its tongue.

I think that when the Hapurubokka is exposed (like when a hunter fishes it out of the sand), it would use the bright colors to stun the attacker long enough for the Hapurubokka to escape.
