To learn more about the regulation of muscle contraction in the structural and functionally different muscles in Ecdysozoa, we have analysed the four EF-hand proteins calmodulin (CaM), troponin C (TnC), essential myosin light chain (eMLC) and regulatory myosin light chain (rMLC) in the velvet worm <em>Peripatoides</em> sp. These proteins are typified by a helix-loop-helix motif and trigger the actin–myosin interaction in muscle tissue and non-muscle cells by coordinative binding of calcium ions. CaM (632 bp) and TnC (853 bp) revealed 4 and 2 potential calcium-binding domains, respectively. Based on analysis of both MLCs, only the rMLC (798 bp) showed one potential N-terminal EF-hand domain and a consensus phosphorylation sequence motif, which suggests a phosphorylation of this myosin light chain. We have compared these results with previously published data from the eutardigrade <em>Hypsibius klebelsbergi</em> and found striking conformity between both taxa. Further, we compared the new sequences with corresponding sequences from nematodes and arthropods retrieved from GenBank
