Morphology

macroinvertebrate = invertebrate (semi-transparent) = macro + in + vertebr + ate

The meaning is mostly predictable as 'a large invertebrate', but in science it specifically means one large enough to be seen without a microscope.

Etymology

Macroinvertebrate combines macro- 'large' and invertebrate 'without a backbone'. So, a macroinvertebrate is an animal like an insect, worm, or snail that is big enough to see but has no backbone.
