Morphology

Pycnogonida = pycnogon + ida

A technical taxonomic name built from Greek combining forms and the class-forming suffix '-ida', which are not productive English morphemes and so do not yield a clear meaning to average learners.

Etymology

Pycnogonida comes from Greek parts pycno- meaning 'thick' and gony meaning 'knee', a helpful image for their chunky leg joints. That's why Pycnogonida are often called sea spiders: they are small, spider-like sea animals with long, jointed legs.
