The production matched each script persona against an oceanic species possessing aligned visual or predatory traits. The table below outlines how DreamWorks translated marine biology into animated mob fiction:
| Character & Actor | Cinematic Archetype | Identified Marine Species | Primary Real-World Trait |
|---|---|---|---|
| Oscar (Will Smith) | Hustling wash worker | Bluestreak Cleaner Wrasse (*Labroides dimidiatus*) | Cleans parasites from visiting reef species |
| Don Lino (Robert De Niro) | Underworld crime boss | Great White Shark (*Carcharodon carcharias*) | Solitary, highly efficient apex predator |
| Lola (Angelina Jolie) | Mercenary femme fatale | Red Lionfish (*Pterois volitans*) | Venomous dorsal spines, aggressive invasive feeder |
| Sykes (Martin Scorsese) | Neurotic loan-shark middleman | Porcupinefish (*Diodon hystrix*) | Inflates body with water to deter predation |
| Ernie & Bernie (Ziggy Marley & Doug E. Doug) | Sykes’ street enforcers | Pelagic Jellyfish (*Scyphozoa*) | Harbors stinging nematocysts along trailing tentacles |
| Don Feinberg (Peter Falk) | Aging, flatulent crime patriarch | Leopard Shark (*Triakis semifasciata*) | Bottom-dwelling feeder, distinct patterned spots |
