Abstract

CASTRO-AGUIRRE, José Luis; SANTANA-HERNANDEZ, Heriberto; ESPINO-BARR, Elaine  and  JIMENEZ-QUIROZ, María del Carmen. First record of Harriota raleighiana (Chondrichthyes: Holocephali: Rhinochimaeridae) in the central Pacific coast of Mexico. Rev. Mex. Biodiv. [online]. 2007, vol.78, n.2, pp.489-492. ISSN 2007-8706.

This is the first record in Mexican central Pacific of the "longnosed chimaera" Harriota raleighiana Goode and Bean 1895, based on a nearly dead female specimen collected at sea surface over very deep water of Manzanillo, Colima. Also, it is the second published report on the occurrence of this species in the eastern Pacific ocean, and seems to support its geographical distribution pattern, which has been classified as cosmopolitan-like type. Morphometric and some biological data are also offered.
