Non‐coding RNAs (ncRNAs), including small ncRNAs (e.g., miRNA, siRNA, piRNA), long ncRNAs (lncRNAs), and circular RNAs (circRNAs), do not encode proteins but play crucial roles in gene regulation, growth, development, metabolism, and immune responses in metazoans. Pancrustacea is the largest clade of the phylum Arthropoda, including many important species such as shrimps, crabs, and insects. In recent years, an increasing numb...
