Collared Myna

The Collared Myna, known scientifically as <em>Acridotheres albocinctus</em>, is a passerine bird belonging to the starling family Sturnidae. <em>Acridotheres albocinctus</em> is recognised by its contrasting plumage, which typically features a dark body with a distinct white collar or band — a feature reflected in both its common and scientific names. As a member of the myna genus Acridotheres, this species generally inhabits open woodland, grassland edges, and areas associated with human settlement, where it forages on the ground for invertebrates, fruits, and seeds. It is reported to occur in Norway according to available range data. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Myna is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is considered stable without significant conservation concerns at this time.

Common hammerhead

The common hammerhead, <em>Sphyrna zygaena</em>, is a cartilaginous fish belonging to the order Carcharhiniformes, family Sphyrnidae. This species is typically found in marine environments and has a distribution that includes the waters of Chile, Denmark, Portugal, Sweden, and Taiwan, reflecting a wide range across both Atlantic and Pacific Ocean systems. As a hammerhead shark, <em>Sphyrna zygaena</em> possesses the characteristic cephalofoil, the laterally expanded head structure that provides enhanced sensory capabilities and hydrodynamic benefits. Hammerhead sharks are generally known to be active, wide-ranging predators within marine ecosystems. No dietary information has been provided for this specific species in current records. Biological traits of this species remain poorly documented in the scientific literature.
