Helioskrill

Helioskrills are predatory creatures that live on Sanghelios. In order to feed themselves, they remain completely still at a location, imitating a rock, waiting for unsuspecting prey to pass by.They are thought to be bird-like as the book The Cole Protocol describes them as living in high, mountainous, rocky places. There is a Sangheili stance modeled on the Helioskrill's hunting position. It allows the performer to appear to be resting, but actually allows the user to be ready to spring to their feet in a matter of less than a second. The user must have a certain amount of stamina, however, because it can cause the muscles in your legs to begin to burn. Thel 'Vadamee used this position whilst being held in a cell by humans in the Rubble with three other SpecOps Elites.

Trivia

 * The "helios" part of their name may derive directly from the name of Sanghelios, their native planet.
