Template:Ratings Helioskrills are predatory creatures that live on Sanghelios. In order to feed themselvesTemplate:Fact, they remain completely still at a location, imitating a rock, waiting for unsuspecting prey to pass by[1].

Trivia

  • Their name, Helioskrills, suggests they are from Sanghelios even to those with limited info.
  • It is highly unlikely that the Sangheili are the "unsuspecting prey" the Helioskrills attack. The Sangheili surely are extremely more powerful than these predators, which would allow them to control their attacks.]
