Redside Blenny. To 8.5 cm (3.3 in) SL (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California), and perhaps to 9 cm (3.5 in) TL (Allen and Robertson 1994) (the latter record unclear as the presence of M. polyporosus Springer, 1959 was unknown at the time). Bahía de Sebastian Vizcaino, central Baja California (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California) into northern Gulf of California (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Benthic; depth: intertidal to 20 m (3–65 ft) (min.: Ruiz-Campos et al. 2010b; max.: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Hastings and Springer (2009) separated this species from M. polyporosus (previously M. hubbsi polyporosus); that species is found from Sinaloa, central Mexico southward to Acapulco, including the Islas Tres Marias.
