Thread-thin worms so numerous that one in every four animals on Earth is one.
means A nematode is a slender, unsegmented roundworm — one of a vast phylum found in soil, water, and as parasites inside plants and animals.
from From Greek 'nema' (thread) plus '-ode' (like, resembling) — literally 'thread-like.' The name was coined in the 1800s by scientists classifying these worms, capturing their defining trait: long, slim, tapering bodies with no segments, unlike earthworms. The root 'nema' also survives in English words like 'nematic' (describing thread-like alignment in liquid crystals).
