Answer 1

Earthworm blood – unlike that of most invertebrates – contains haemoglobin, a protein in red blood cells to carry oxygen around their bodies. ... The commonearthworm or nightcrawler (Lumbricus terrestris), for instance – one of the UK's largest earthworm species – comes up to the surface at night to feed on dead leaves.
