A splinter is an insectoid quadruped creature that Samus encounters on the planet Aether. They live in cocoons constructed of their own secretions when not hunting for food, though movement outside will awaken them and other splinters nearby. Splinters can be quite dangerous in large numbers. They bear a similar appearance to many other creatures, such as Hoppers, Beetles, and even the Ing.
 Logbook Entry
When it isn't hunting, a Splinter will secrete a protective cocoon around itself and enter a state of hibernation. Localized seismic disturbances will awaken the Splinter, triggering a state of blood frenzy in the process. While in this state, a Splinter emits pheromones that trigger frenzy in all nearby Splinters. Disturbing a pack of sleeping Splinters is not advisable.
