Meaning and Definition
A large, slow-swimming, coastal shark (Carcharias taurus) with a greyish-brown body and a formidable, but generally non-aggressive, disposition towards humans.
A species of shark also known as the sand tiger shark or ragged-tooth shark, found in subtropical and temperate waters. It is notable for its habit of maintaining buoyancy by gulping air at the surface and for being one of the few shark species that exhibits intrauterine cannibalism.
Dialectal Variation
British vs American Usage
Differences
The spelling of the colour: British English predominantly uses 'grey nurse shark,' while American English uses 'gray nurse shark.' The species is less commonly referenced in everyday UK English due to its absence from British waters.
Connotations
Similar in both varieties: evokes a mix of fear (due to appearance and the word 'shark') and curiosity (due to the unusual combination with 'nurse'). In Australia, it has specific conservation connotations.
Frequency
More frequent in Australian, South African, and U.S. (Atlantic coast) English due to its local presence. Rare in inland or non-coastal dialects.

Learning
Memory Aids
Mnemonic
Imagine a nurse in a grey uniform who is also a shark – she looks stern but is actually quite calm and just 'cruises' the hospital corridors (the ocean). Grey (colour) + Nurse (profession) + Shark (animal).
Conceptual Metaphor
THE OCEAN IS A HOSPITAL; THE SHARK IS A CARETAKER/INHABITANT. This is ironic, as the 'nurse' label is misleading but creates a metaphor of a resident entity within a larger system.
