Remarks. Burghardt & Wägele (2014) followed the growth of M. engeli in a controlled environment noticing changes in the cerata shape and colouration. The specimens examined here are identical to the adult morphotype in Burghardt & Wägele (2014). This is the first record of this species in the western Indian Ocean.
