The Alpha Splinter's cocoon at Temple Sanctuary

Splinter Cocoons are small, organic hives that house tired or sated Splinters. If the cocoon is destroyed, it will kill the Splinter inside, but not before it emits a shriek that alerts all Splinters nearby into battle. Splinters will violently burst from their cocoons if they sense a threat in the area; the method in which they detect the enemy is unknown, although it is likely because of a heightened sense.

An Alpha Splinter nests within a far larger cocoon than its brethren. Curiously, all of the Splinter Cocoons inside the Temple Sanctuary were surrounded by an energy field that impeded Samus from scanning them correctly. This field may have been caused by interdimensional disturbances from which the Ing would emerge and possess the creatures.

Curiously, the common Splinters inside the Great Temple of the Luminoth did not violently burst out of their cocoons, which is the case with all other Splinters found in Temple Grounds. Instead, through the use of their webbing extruded from their rears, they gently lower themselves from the ceiling onto the ground. Only the Alpha Splinter exits its cocoon in the common manner.

Morphology: Splinter Cocoon
Protective structure for sleeping Splinters. Destroying this structure will eliminate the Splinter inside, but it will also alert other Splinters nearby.

Logbook entry

Splinters will enter their protective cocoons when tired or sated. The cocoon is durable, but can be destroyed by weapons fire. Destroying a cocoon will kill the Splinter inside; when this occurs, the dying Splinter will emit a shriek that will alert all nearby Splinters in hibernation. This will drive them into battle frenzy as a defense mechanism.
