Ventura et al. (2006)
listed
O. alexandri
for Martin Vaz among the echinoderms amassed during the REVIZEE-Central Program (Evaluation of the Living Resources in the Brazilian Economic Exclusive Zone, sampling station C5-48R,
23°53’S–
45°26’W
,
52 m
.

). Surprisingly enough,
O. alexandri
was not integrated into the atlas of the fauna caught during the REVIZEE-Central Program. In Martin Vaz, that species occurred well beyond the depths of our typical SCUBA diving survey.
