#aheloide
- Acheloids — A term given to a category or family of marine or fossil organisms, or insects in older taxonomic classifications (sometimes correlated with Coleoptera species or primitive crustaceans), whose anatomical structure resembles a fluid shape or traits historically associated with aquatic deities (Achelous). In a modern sense, the term appears in niche papers to describe specimens with a specific hydrodynamic morphology.
