Hypothesis
The study aims to describe two new species of the genus Rissoella from Venezuela.
Conclusion
Two new species of Rissoella were identified and described, expanding the known diversity of this genus in the Caribbean.
Supporting Evidence
- Two new species were discovered in the Caribbean region.
- Rissoella morrocoyensis sp. n. and Rissoella venezolanicola sp. n. were described.
- Both species have unique anatomical features that differentiate them from known species.
Takeaway
Scientists found two tiny new types of snails in Venezuela that live on sea plants.
Methodology
Specimens were collected by snorkelling and examined using a stereomicroscope and SEM for anatomical details.
Limitations
The study may not cover all species in the region due to the difficulty in identifying small gastropods.
