Helioskrill (Earth-5875)

Helioskrill are massive predatory reptiles that inhabit high mountainous regions of Zolam, Qivro, on Sanghelios.

Anatomy and physiology
The helioskrill are massive, averaging 5' 8" (172,5 cms). They have creamy white skin and deep, amber eyes, much like the average sangheili. They are quadrupedal and their legs and arms are clawed. Their legs are digitigrade, and many bony protusions jut forth from their tails, legs and shoulders. Helioskrill are strong creatures, capable of severely injuring a sangheili and kryn'qodon, the latter which serve some of their natural preys. Their blood is dark purple.

Natural capabilities
As predators near the top of the food chain on Sanghelios, helioskrill developed several methods of hunting. Most famously, they remain still at locations, and their skin color changes to imittate their environments. If a helioskrill is in a rocky area, they will change their skin color to match the location and imitate their surroundings, waiting for its prey to pass. A sangheili martial arts stance is modeled after the hunting position of the hellioskril; in it, the performer fakes being resting, while they will spring to their feed in less than a second to take down their opponents. Notably, this position was used by Thel 'Vadamee and Jora 'Konaree during the Battle of the Rubble.
