How do Peruvian and Chilean specimens compare to the Costa Rican find?

Question

Accepted Answer

Peruvian and Chilean specimens are still being checked because they look very similar to the Costa Rican ghost shark find
Peruvian and Chilean specimens collected earlier are described as very similar to the ghost shark species found near Cabo Blanco and Cano Island in Costa Rica. Costa Rican researchers have not finalized the conclusion because they are still comparing those Peru and Chile specimens with the Costa Rican species. The available details do not specify which traits match or differ, only that the overall similarity is strong enough to keep the identification under review.
Scientists say the Peru and Chile specimens are “very similar” to the Costa Rican species
Arturo Angulo Sibaja, a biology professor at the University of Costa Rica, said earlier specimens from near Peru and Chile resemble the Costa Rican species. He did not provide the specific comparison results, such as which physical traits or genetic markers align between the regions. Because the evidence is still being weighed, the final determination has not been completed.
The comparison is still ongoing before a final conclusion
Sibaja said researchers are still comparing the Peru and Chile material with the Costa Rican ghost shark before finalising the conclusion. This means the status of whether the specimens represent the same species or different ones remains unresolved. The report frames the work as a step that must happen after the initial similarity is noticed.
The Costa Rican find is characterised by specific traits, but those details are not applied to Peru and Chile
The Costa Rican ghost shark (Rhinochimaera costaricana) was described with a shorter snout, a darker coloration pattern, and a much longer spine on its dorsal fin. It also came with genetic analysis indicating no reproductive contact with other ghost sharks. However, the information provided does not state whether the Peru and Chile specimens show the same shorter snout, darker pattern, or dorsal spine length, nor whether their genetics match.
Genetic results for the Costa Rican species do not automatically settle the Peru and Chile question
The genetic analysis mentioned in connection with the Costa Rican species indicates no reproductive contact with other ghost sharks. That finding supports the distinctiveness of the Costa Rican species, but the Peru and Chile specimens are still under comparison. With no specific genetic or morphological results for the Peru and Chile material included here, the comparison question remains open.
