Skates are a diverse group within the chondrichthyans
and comprise a large component of the bycatch in many
demersal fisheries. The distribution of the Deepsea
Skate, Bathyraja abyssicola, is presently known
to be limited to the northern temperate Pacific Ocean.
We filmed B. abyssicola from a remote operated
vehicle during surveys undertaken on a seamount located
north of Darwin Island within the Galapagos Marine
Reserve in 2015. This sighting represents the first
record of B. abyssicola in the Galapagos Marine
Reserve and the first record of the species from anywhere
in the tropical eastern Pacific Ocean. The large range
extension of this species to tropical low-latitude
waters of the Pacific Ocean is a critical contribution
to conservation biology of this poorly known species,
especially since deepwater skates and rays are generally
over-exploited. This new record also highlights our
limited knowledge of unique deepwater ecosystems in
general and those of the Galapagos Islands in particular.
