Which risk increases as a deep-sea siphonophore detaches its gas-filled pneumatophore?

💡 Explanation

Detaching the pneumatophore removes hydrostatic equilibrium maintenance via buoyancy; therefore, the siphonophore loses its ability to control depth and orientation. This loss of hydrostatic equilibrium occurs because bladder deflation affects Archimedes' principle, rather than temperature or osmosis regulation.
