1. It is an aquatic carnivorous plant. The golden threadfin uses small sac-like traps to suck in and digest small organisms such as mosquito larvae and microcrustaceans. Photo: wikimedia. 2. The bait trap works like a vacuum. The bag-shaped traps have a flip-top lid, and when the prey touches it, the lid opens and sucks the prey in less than a millisecond. Photo: wikimedia.
3. They don’t have roots like regular plants. Instead of clinging to the bottom of the lake, they float or cling to other plants with their slender stems and tiny tendrils.

This is a characteristic that helps identify the species. Photo: fierceflora.com.
5. Widely distributed in Southeast Asia. Utricularia aurea is found in Vietnam, Thailand, Cambodia, Indonesia... in ponds, lakes, and quiet freshwater swamps. Photo: wikimedia. 6. Survives by digesting animals. Due to the lack of nutrients from the soil, this plant compensates by decomposing its prey to obtain nitrogen and phosphorus. Photo: Pinterest. 7. Highly adaptable to nutrient-poor water environments. The plant thrives in shallow, mineral-poor waters where other plants have difficulty surviving. Photo: Pinterest.
8. Contributes to the balance of freshwater ecosystems. Golden threadworms help control the number of small organisms such as mosquito larvae, contributing to population regulation and reducing the risk of disease spread. Photo: entomologytoday.org.
