Gastropod, whole spiral shell
Family
Ampullariidae (Apple snail family)
Size
Approximately 2 inches in height, which is typical for a sub-adult specimen. Adults of this species can reach up to 3 to 6 inches.
Color & Pattern
Solid deep olive-brown to dark chestnut coloration with a smooth, glossy, polished appearance. The surface lacks strong patterning, displaying a uniform dark hue.
Rarity
Very Common
Habitat
Freshwater habitats including slow-moving rivers, marshes, swamps, lakes, and drainage ditches, often found in areas with abundant aquatic vegetation.
Geographic Range
Native to South America, but widely introduced globally as an invasive species in North America, Asia, and Europe.
Description
A robust, globose freshwater gastropod shell featuring a low spire, rounded body whorl, and a smooth exterior texture. The shell is sturdy and adapted for protecting the animal in shallow freshwater environments.
Key Features
Globose, rounded shape, low to moderately elevated spire, deep suture channels, and dark brown coloration.
Collector Value
Low to moderate value for shell collectors, as they are very common globally, though popular in educational contexts and among malacologists studying invasive species.
Condition Notes
Good condition with intact whorls and glossy surface, showing minimal wear and no significant fractures.
Interesting Facts
Apple snails are capable of breathing both air and water using a combination of a gill and a lung, an adaptation for surviving in stagnant, oxygen-poor water.
Ecological Role
Acts as an aggressive herbivore in non-native regions, often causing severe damage to aquatic ecosystems and agricultural crops like rice.
Similar Species
Pomacea maculata (Island Apple Snail), which is typically larger and can have distinct banding patterns.
Beach Finding Tips
Found along the muddy banks, shallow edges, and floating vegetation mats of freshwater lakes and rivers, rather than marine beaches.
