Praying Skitter Leaf

The Praying Skitter Leaf is a boss enemy Skitterling found in Pikmin Z, and the smallest bosses in the game. It has an insect-like body, with a set of long, sharp pincers.

Biology
The Praying Skitter Leaf is a ambush predator, and remains motionless until prey gets close. During the boss fight, it will move very quickly, and slice at you with its pincers.
 * Diet: insects
 * Predators: large carnivores

Piklopedia entry
''The Praying Skitter Leaf is another one of many examples of convergent evolution, evolving to mirror a creature that once existed on this planet many years ago. It is the first true Skitterling to have evolved into a large predator.''

Strategy
The skitterling won't target your Pikmin, and instead strictly targets the captains, so be sure to avoid the lunges the Praying Skitter Leaf will make at you. Its back is covered in leaf armor, so in order to harm it, have one of your Pikmin pick up a bomb rock, and throw it near the boss, resulting in the armor exploding off for an opening to attack.
