Crocodilefish: Camouflage Masters with Venomous Defense

*Stonefish are the world's most venomous fish*They get their common name from their likeness to the stoney habitats that they prefer to lurk in*They’re often mistaken for a stone or part of a coral reef. But the failure to distinguish a stonefish from a stone due to this camouflaging can have life-threatening consequences*Their skin is covered in a rough, mottled texture, varying in colour from grayish-brown to reddish-brown*A stonefish can stay out of water for up to 24 hours thanks to its special adaptations. Their tough, slimy coating keeps their skin moist and helps them to breathe air through their gills, even on land
