Froggo Fren #48/Spooktober Day 27 - Spongy Spikey Skull

The skull of a Greening's frog (Corythomantis greeningi) Endemic to Eastern Brazil, this is one of the few species of frogs that directly injects venom into attackers via their skull spines which protrude from their upper lip (most fairy godmothers don't recommend trying to kiss this frog; not that many would be tempted to anyway, even with their skin on, they won't be winning any beauty pageants)
