Could this ghost shark species be found along more of the Pacific coast?

Question

Accepted Answer

This Ghost Shark Species May Have a Wider Distribution Along the Pacific Coast

Costa Rican scientists suggest that the newly identified ghost shark species, tentatively named Rhinochimaera costaricana, likely inhabits a broader area along the Pacific coast of Central and South America. Initial observations of specimens collected near Peru and Chile reveal strong similarities to the Costa Rican discovery, indicating a potential distribution beyond its initial finding. Further genetic and morphological comparisons are underway to confirm these findings and delineate the species' full geographic range.
Distinct Physical Characteristics Identified

The ghost shark discovered off the coast of Costa Rica exhibits several distinct features compared to its relatives. These include a notably shorter snout, a darker overall coloration pattern, and a significantly longer spine on its dorsal fin. These specific traits are crucial in distinguishing it as a potentially new species within the Rhinochimaera genus.
Genetic Analysis Suggests Reproductive Isolation

Genetic analysis conducted by researchers at the University of Costa Rica indicates that this newly identified species does not engage in reproductive activities with other known ghost shark populations. This genetic divergence supports the classification of the Costa Rican specimen as a distinct species, separate from other ghost sharks found globally.
Similar Specimens Found in South America

Specimens collected from waters near Peru and Chile share significant similarities with the ghost shark found in Costa Rica. This geographical proximity and morphological resemblance are key factors leading scientists to hypothesize a broader distribution for this species along the Pacific coast of both Central and South America.
Potential for Broader Pacific Range

Arturo Angulo Sibaja, a biology professor at the University of Costa Rica, stated that it is "most likely" that this new species has a wider distribution. The similarities observed between the Costa Rican ghost shark and those found further south in Peru and Chile strongly suggest that its habitat extends along the Pacific coast of the Americas, though precise boundaries are still under investigation.
