Horned Cannon Beetle

The Horned Cannon Beetle is a Lithopod found during the expedition of the Rescue Corps onto PNF-404. At first this species was mistaken as a subspecies of Armored Cannon Beetle due to its appearance, but it's revealed during later study that it migrated from another continent as a non-native species to the area which its discovered.

Biology
Although the species strongly resembles the earlier species of Armored Cannon Beetle, observations show a few distinct characteristics to the species such as a set of "mandibles" along the side of the circular mouth, vaguely resembling horns and giving the creature its name. The natural exoskeleton is also more segmented than that of its close relative. The hole above its body is also aimed slightly higher towards the sky than directly ahead as in Armored Cannon Beetles.

Although males are capable of shooting rock-like material from their mouths, fully mature females lose this ability as the hole above their heads close off once they reach sexual maturity. These females, while described by Captain Olimar, hadn't been observed by the Rescue Corps however.

Reproduction
Eggs of the Horned Cannon Beetle are laid on various rocks by the females, which are then launched away by the male. This exact behavior is unclear, but it is known that the young of the animals consume the rock they are laid on once they hatch.

Cannon Beetle "Hybrid"
Curiously, this species is able to reproduce offspring with the Armored Cannon Beetle, create a form of Cannon Beetle hybrid. These hybrids themselves are only described in full by observations from Captain Olimar shortly after the discovery of the Horned Cannon Beetle species. These are described as being more aggressive than either species, known for attacking Armored Cannon Beetle larva with little to no provocation.
