Amazonian Freshwater Shrimp Morphometrics and Growth Patterns

Caio Santos Nogueira provides the first morphometric and biological data for the freshwater shrimp species Euryrhynchus amazoniensis and E. burchelli. The dataset includes measurements for carapace length and cheliped articles from specimens collected in floodplain areas near Manaus, Brazil. It was last updated on 2026-04 17 and is licensed under CC-BY-4.0.

Use Cases

• Analyze relative growth patterns based on carapace length and cheliped measurements.
• Study sexual dimorphism based on comparisons of male and female size and cheliped development.
• Investigate handedness and heterochely patterns based on cheliped side occurrence data.
• Identify male morphotypes based on morphological analyses described for E. amazoniensis.

Strengths

• Provides first biological data for Euryrhynchidae shrimp species, filling a knowledge gap.
• Includes measurements for carapace length and multiple cheliped articles.
• Dataset is 5.5 MB, facilitating quick download and inspection.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the collection sites near Manaus, Brazil.
