Habitat & Fossil Locality

Slow-flowing freshwater (where chironomid larvae live alongside it)

💡 Everyday Comparisons for Size, Mass & Speed

💡 Because of its ability to regenerate even after being cut into pieces, it is used as a model animal in biology classes and regeneration research (Frontiers in Genetics).
💡 A study showed that it can be raised in the laboratory for over 1 year on bloodworms instead of beef liver, offering an experimental method that reduces the use of vertebrates (PMC).
💡 A length of 1 cm is similar to two grains of rice (about 5 mm each) placed end to end (Comparison).

#플라나리아#Dugesia japonica

📖 1. Overview

Dugesia japonica is a flattened freshwater flatworm famous for its regenerative ability to rebuild an entire body from just a small body fragment.

🦴 2. Anatomy & Morphology

Its body length is around 1 cm in laboratory specimens. Even when cut into pieces, it regenerates its head and all parts of its body.

🔍 3. Ecology & Behavior

It naturally feeds on insect larvae such as bloodworms (chironomid larvae), and a study has maintained it in the laboratory for over 1 year on bloodworms alone. In laboratories, it is commonly fed ground beef or chicken liver.
