First evidence of prickly shark, Echinorhinus cookei Pietschmann 1928, aggregation on seamounts in the eastern Pacific, Panama.

In May 2022, twelve prickly sharks, Echinorhinus cookei Pietschmann 1928, were sighted at 151-350 m depth in the Cordillera de Coiba seamounts, Pacific Panama. This discovery expands our knowledge of the distribution and habitat use of this rare deep-sea species. It underscores the potential significance of the Cordillera de Coiba seamounts, an offshore marine protected area, as a critical habitat for E. cookei, a species threatened by commercial fishing. Although unverified reports exist on its presence in the tropical eastern Pacific, this publication represents the first documented record of live specimens of E. cookei in Panama.
