Evolutionary Milestone
Mollusks posses five evolutionary milestones: eukaryote, tissues, bilateral symmetry, body cavity, and enclosed body cavity.
Habitat
Most live in the ocean but some live in freshwater or moist land habitats.

Anatomical/ Structural Features
How do they acquire nutrients
Mollusks use a radula to drill, scrape, grate, or cut food. It depends on the class of the mollusk for exactly how they eat.
What do they eat
algae, plankton, plants, krill
What eats them
fish and turtles
Symmetry
bilateral symmetry
Mobility
Reproduction
Most mollusks have separate sets and will reproduce sexually through external fertilization. Although, land species are hermaphrodites.
