Hypothesis
What are the host species of pygmy seahorses?
Conclusion
Pygmy seahorses are associated with more gorgonian and hydrozoan hosts than previously assumed.
Supporting Evidence
- Seven new associations of pygmy seahorses with host species were recognized.
- Hippocampus bargibanti is associated with at least five different Muricella species.
- Hippocampus denise lives in association with at least three different Annella species.
- Hippocampus pontohi was observed on four hydrozoan species.
Takeaway
Pygmy seahorses live on certain types of corals and can be found in different colors that help them blend in.
Methodology
Fieldwork was conducted in various locations in Indonesia and Malaysia, where pygmy seahorses were observed and their host species identified.
Potential Biases
Previous identifications of host species may be erroneous due to non-specialist assessments.
Limitations
The study relies on visual identification, which may lead to errors in species classification.
