Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.

Question

Refer to the figure below based on a study by Purcell, S., 2002. The study 15 points
compared the morphology of wild juvenile trochus (A) and hatchery
produced trochus (B). You will note that wild juveniles (A) have spiked
shell whorls. In contrast, hatchery-produced juveniles (B) of the same
size have smooth shell whorls even at a smaller size. Describe the
adaptive advantage that the spike whorls confer to these juvenile
topshells. What kind of environmental selective pressure, could have led
this type of morphological adaptation in topshells. *
