← Nature & AnimalsWhich outcome occurs when a physoclistous fish's gas bladder inflation rate exceeds resorption capacity during rapid ascent?
A)Development of fatal swim bladder overexpansion✓
B)Suffocation due to depleted blood oxygen
C)Dehydration from increased osmotic pressure
D)Muscular failure due to altered buoyancy control
💡 Explanation
When inflation rate exceeds resorption, a physoclistous fish's gas bladder over expands due to rapid pressure decrease because resorption is slow, leading to barotrauma damaging internal organs. Therefore fatal swim bladder overexpansion results, rather than suffocation, dehydration, or muscular failure involving respiratory or osmotic processes.
