Did you know that one fish species lives only in a single Croatian lake, and nowhere else on Earth? The Croatian riffle dace (Telestes polylepis) survives in only one confirmed location, the Šmitovo Lake drainage. It’s just one of many remarkable endemic species of the Balkans, Europe’s unique biodiversity hotspot. What are endemic species and […]

We often picture a clear divide  between water and land. Fish stay in rivers, forest belong to mammals, and canopy is ruled by birds and insects. But nature is far more complex than that. Energy and nutrients constantly move between freshwater and terrestrial ecosystems, quietly shaping life on both sides.  Over the past few decades, scientists have discovered that this boundary […]

To end on a high note, meet the true divas of the freshwater’s habitats: the larvae of case-building caddisflies (order: Trichoptera). These are the most fashionable tiny creatures you’ll find underwater. When Style Meets Survival Caddisflies larvae construct their own portable homes, protective cases they carry wherever they go. These cases serve as both protection […]

The water’s surface is a boundary between two worlds and only a few creatures navigate is as skillfully as the backswimmers (family: Notonectidae), who have mastered life right in between. Life on the Upside Down These small freshwater insects live right at this thin line, just beneath the surface, upside down. Special hair covering their […]

What insect can swim, fly – and hunt frogs?   In this edition of Tiny but Mighty, we introduce another small but fierce freshwater predator: the diving beetle!  Diving beetles (family: Dytiscidae) are true multitalents of the freshwater world. You can usually spot them in ponds and shallow lakes, but these remarkably versatile insects are […]

A series of Tiny but Mighty Freshwater ecosystems are full of life. We tend to notice the obvious residents first: fish darting through reeds, frogs calling from pond edges, or we catch the splash of a beaver’s tail.  But beneath the surface lies a far richer, and largely unseen world, powered by tiny yet mighty […]
