Summary
| Description |
English: Clea helena is a carnivorous species of freshwater snail, here shown with its siphon protruding. Most species of snails with a siphon use it for breathing, however in Clea helena the siphon is also adapted to be used when hunting other snails. The plants in the immediate background are a small species of Sword plant, Echinodorus quadricostatus var. magdalenensis. Svenska: Clea helena är en köttätande art av sötvattenssnäcka, som främst lever av andra snäckor. Här visas den med sin periskop-liknande sifon utskjuten. De flesta arter av sötvattenssnäckor som har en sifon använder den för att underlätta andningen, genom att använda den som en sorts "snabel" som pumpar vatten över gälarna. Utöver denna funktion använder Clea helena dessutom sifonen för att jaga andra sniglar med. Växterna i bakgrunden närmast snäckan är en svärdsvalting, Echinodorus quadricostatus var. magdalenensis. |
