3 males

914–925 m

Remarks.
Previously known from off California and from the Gulf of California (from ca 26°N south to off Tres Marias Islands). The present record extends the northernmost limit of
M. depressa
in the Gulf of California by over two degrees of latitude, to ca
28°16’N
.
The recorded depth range of
M. depressa
in the Gulf of California is from
780 to 1300 m
, just below the OMZ (Hendrickx 2003). As noted by
Hendrickx & Serrano (2010)
, deep-water species occurring below the OMZ off western
Mexico
are unable to migrate to shallow water due to the physiological barrier formed by the OMZ and they form a distinct community, with no representative of the continental shelf community.
