Section 2: Lakefly Invertebrate Identification
Estimated Time For Lesson: 3 minutes
ID Notes
Freshwater snails live in shells.
They have a wide variety of coiled or flattened spiral shaped shells which range in sizes.
Can be brown, other colours, striped, or patterned
Many are small (4mm), while others can be very large
They will often stick to the bottom of the sampling tray
Avoid confusing these with bivalves (these have shells of two similar parts, e.g. freshwater mussels) and terrestrial snails.
They can be found on lake shores and among vegetation, feeding on algae, fish eggs and detritus.
