Natural Habitat

Ephemeral or temporary freshwater pools, ponds, and rice paddies that dry out seasonally.

Diet & Feeding

Omnivorous; feeds on organic detritus, algae, bacteria, and small invertebrates like mosquito larvae.

Behavior Patterns

Known as 'living fossils', they have a rapid life cycle designed to survive in temporary waters. They lay drought-resistant eggs that can remain dormant for years until rain triggers hatching.

Risks & Benefits

Generally harmless to humans. They are beneficial in ecosystems for controlling mosquito populations but can occasionally be considered pests in rice fields due to their digging habits.
