Morphology

Actinopoda = actin + poda

A technical taxonomic name built from Greek combining forms (actino- + -poda) that are not productive standalone English morphemes for average learners, so the meaning is not readily derivable.

Etymology

Actinopoda comes from Greek parts actino- meaning 'ray' and -poda meaning 'foot', so it literally means 'ray-foot'. A helpful image is tiny, single-celled sea creatures with thin, ray-like 'feet' that they use to move and catch food, which explains the modern meaning.
