Melanoides tuberculata

Malaysian trumpet snail

A pointed-shell freshwater snail that burrows through lake sand, grazes biofilm, and processes leftover organics while usually staying visible at low density.

Identity & Origin +

Common Name: Malaysian trumpet snail
Scientific Name: Melanoides tuberculata
Realm: Freshwater
Biome: Freshwater Lake
Date First Introduced: July 09, 2025

Population Dynamics +

Current Estimated Population: Adults and juveniles present; three juveniles immediately observed on 2026-05-21, with the species normally visible at low density rather than high abundance.
Population Status: Established
Carrying Capacity Status: Stable/persistent at modest density; competing successfully alongside the lake snail community without becoming highly abundant.
Date Last Observed: May 21, 2026

Section Notes

Juvenile Malaysian trumpet snails were consistently observed in the Freshwater Lake on 2026-05-21 and appear to be growing over time. Adults and juveniles are both present, confirming continued reproduction and persistence. Density remains modest, but low visible abundance is consistent with prior observations of this species in the system.

Trophic Ecology +

Trophic Level: Primary Consumer
Feeding Niche / Method: Algae grazer and detritivore
Dietary Inputs: Algae, biofilm, microbial films, and soft surface growth

Section Notes

Trophic classification is Primary Consumer. Food-web role: Algae and biofilm grazer. Feeding method: Algae grazer and detritivore. Dietary inputs: Algae, biofilm, microbial films, and soft surface growth

Environmental Tolerances +

Life Cycle & Reproduction +

System Reproduction Status: Confirmed; juveniles are present and visibly developing in the Freshwater Lake.

Section Notes

Possible juvenile observations on 2026-04-13 and hatchling emergence on 2026-04-17 are now supported by continued juvenile presence and growth on 2026-05-21.

Ecological Role & Symbiosis +

Ecological Role: Algae control
Microhabitat Preference: Lake substrate, glass, and surface films; juveniles observed within the Freshwater Lake at low but consistent visible density.

Section Notes

Persistent burrowing detritivore and algae/biofilm grazer. Juvenile development suggests the lake substrate and food resources can support ongoing recruitment.

Freshwater

A still freshwater habitat where submerged plants, tiny grazers, shrimp, snails, and crayfish are rebuilding the lake's food web after fish pressure changed.
