The collar-like gill structure visually separates it from streamlined pelagic sharks. In dim deep-sea footage, the frill enhances its almost mythical silhouette.
Retaining such ancestral traits reinforces the idea that deep-water habitats can preserve evolutionary features long abandoned elsewhere. The result is a living organism that appears designed from an earlier geological era.
