Mourr

The common guitarfish, <em>Rhinobatos rhinobatos</em>, is a cartilaginous fish belonging to the order Rhinopristiformes, family Rhinobatidae. It is a member of the guitarfish group, characterized by a flattened body with a distinct guitar-like silhouette formed by the fusion of the head, pectoral fins, and trunk. <em>Rhinobatos rhinobatos</em> is assessed as Critically Endangered on the IUCN Red List, representing severe conservation concern and indicating that this species faces an extremely high risk of extinction in the wild. Pressures such as overfishing and bycatch are commonly implicated in the decline of guitarfish species globally. Detailed habitat, range, and country distribution data are not available for this species in current records. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
