Molluscarium description

Molluscarium

Dive into a living world of mollusks where hundreds of species awaken on screen. Molluscarium lets you discover and collect over 500 hand‑drawn mollusk varieties across nine themed packs, each with its own movement, habitat, and behavior.

Nine diverse packs to explore

  • Garden & Forest – Snails slowly crawl across mossy terrain.
  • Beach & Tidepool – Limpets and conchs cling to sun‑warmed rocks.
  • Freshwater – Peaceful pond snails drift through calm waters.
  • Coral Reef – Nudibranchs glide among vibrant corals.
  • Spiral Shells – Heavy‑shelled beauties creep along the sea floor.
  • Bivalves – Oysters and mussels rhythmically open and close their shells.
  • Hunters – Cone snails and predators stalk their prey.
  • Cephalopods – Octopuses and squid jet through open water.
  • Deep Blue – Mysterious creatures drift in the eternal dark.

Real‑time growth

Every mollusk begins as a tiny larva. Watch them feed, grow, and metamorphose into their adult forms—each with distinct poses and behaviors. Land snails crawl, bivalves anchor to the substrate, and cephalopods burst through the water with jet propulsion.

Idle and relaxing

Your habitats continue to thrive while you’re away. Return to find your mollusks grown, earning income, and discovering new behaviors. Gentle ambient sounds and hand‑drawn art make Molluscarium a soothing background companion.

Customize habitats

Design the perfect environment with upgradable backgrounds. Observe interactions as bottom‑dwellers hug the substrate and swimmers explore every corner—creating a personalized underwater world.

Collect rare variants

Each species can appear in four visual variants—Normal, Painted, Golden, and Rainbow. Hunt for the rarest combinations across seven rarity tiers from Common to Ancient.

Global competition

Climb global leaderboards by collection value and species discovery count. Show off your rare finds to players around the world and compare your mollusk menagerie.
