A Phazon Shriekbat is a Phazon version of the common Shriekbat. They are found on the G.F.S. Valhalla. They possess the same basic "closed loop" body form as the Urtragian and Aetherian Shriekbats (albiet with considerably longer tails) and detonate with a small Phazon shockwave, but are otherwise identical in behavior to their cousins.
"Even more aggressive than normal species, Phazon Shriekbats will not hesitate to attack any creature that wanders too close. Their dive-bomb attack erupts in a burst of Phazon energy, which usually proves fatal to weaker organisms. These Shriekbats are mainly found in areas with high amounts of Phazon. Instead of the usual insects and small creatures Shriekbats usually feed on, they have come to rely on Phazon as a food source."
