Conclusion
The study provides a comprehensive overview of the global biodiversity of the class Ascidiacea, highlighting the high species richness in tropical regions and the risks posed by invasive species.
Supporting Evidence
- Sixty percent of described species are colonial.
- Species richness is highest in tropical regions.
- The highest number of species and families is found in the order Aplousobranchia.
- Many new species continue to be discovered and described each year.
- Ascidians are a key ecological group due to their invasive potential.
Takeaway
Ascidians, also known as sea squirts, are a diverse group of marine animals with many species found in tropical waters, but they can also be invasive and harm local ecosystems.
Methodology
The study involved a literature review and analysis of species registered in the World Register of Marine Species to compile a systematic list of ascidian species.
Potential Biases
The reliance on existing literature and databases may introduce biases in species identification and distribution.
Limitations
The inventory is likely incomplete as many areas are poorly studied and new species continue to be discovered.
