Tips
usage
Two very different meanings: (1) in biology classes, 眼虫 = Euglena, a protist famous for blurring the plant/animal line; (2) in parasitology, 眼虫 = the eye worm (Loa loa, Thelazia) that physically lives under the conjunctiva. Context decides.
memory
Euglena has an 眼点 (eyespot / stigma) — a red photoreceptor that steers it toward light. That little 'eye' gave the organism its Chinese name.
