← Nature & AnimalsWhich risk increases when a fish over-inflates its swim bladder beyond its elastic limit at depth?
A)Buoyancy fluctuation causing uncontrolled ascent✓
B)Increased susceptibility to parasitic infestations
C)Reduced predation risk due to higher speed
D)Enhanced sensory perception of vibrations
💡 Explanation
When a fish considerably ascends inflates its swim bladder via baroreceptors past its limit, the bladder exceeds elastic capacity, reducing control and positive-buoyancy causing an uncontrolled ascent. Therefore, excessive ascent the result, rather than lower predation or vibration sense, which offer other advantages.
