Hairy Frogfish

The hairy frogfish is covered in elongated dermal appendages that mimic the texture of algae-encrusted rock or sponge, rendering it effectively invisible on Lobster Wall's richly colonised substrate. It uses a worm-like esca to lure small fish and shrimp within striking range, swallowing prey whole in a jaw expansion lasting under a millisecond. Kapalai's gentle current keeps the wall surface well-oxygenated and the frogfish well-fed, supporting multiple resident individuals across different depth bands.
