- noun
- Specialized

Morphology
geryonid = Geryon (opaque) = geryon + id
The taxonomic base is an obscure proper name and '-id' is a specialist suffix, so the compound is not transparent to average learners.
Etymology
Geryonid comes from the mythic name Geryon, a 'giant' with three bodies, and naturalists gave his name to a family of deep-sea crabs because of their strange, strong look. So a geryonid is a deep-sea crab in that family.
