A unique feature of adult echinoderms compared to their larval stage is their body symmetry. Which statement correctly describes this symmetry shift along with their circulatory/excretory system features?

Adults are radially symmetrical, larvae are bilaterally symmetrical; Specialized excretory system is absent
Adults are bilaterally symmetrical, larvae are radially symmetrical; Excretory system is well developed
Both adults and larvae are radially symmetrical; Excretion occurs via Malpighian tubules
Adults are asymmetrical, larvae are radially symmetrical; Water vascular system functions exclusively for excretion

Correct answer · Option 1

Adults are radially symmetrical, larvae are bilaterally symmetrical; Specialized excretory system is absent

Explanation

Adult echinoderms exhibit radial symmetry while their free-swimming larvae exhibit bilateral symmetry. Echinoderms completely lack a specialized excretory system.

A unique feature of adult echinoderms compared to their larval stage is their body symmetry. Which statement correctly describes this symmetry shift along with their circulatory/excretory system features?
