Which three major habitats have gastropods successfully colonized?

Gastropods are among the few groups of animals that have successfully colonized all three major habitats. These environments are:1

• Ocean: Marine gastropods are highly diverse, inhabiting areas ranging from the intertidal zone and coral reefs to deep-sea trenches and hydrothermal vents.23
• Fresh water: These gastropods are commonly found in ponds, streams, lakes, and marshes, and some have even adapted to groundwater and hot springs.23
• Land: Gastropods have successfully adapted to terrestrial life, occupying diverse environments that range from wet forests to barren deserts and high-altitude alpine meadows.23

The ability of gastropods to thrive in these varied environments is largely attributed to the plasticity of their body and organ systems.4
