Quick answers

Is Nemo an ocellaris or a percula?

Pixar Nemo is styled on Amphiprion ocellaris (this atlas type). Shops still mix ocellaris and percula under one common name.

How does sex change work?

A group is a female, a breeding male and non-breeders. If the female dies, the male changes sex. The film missing-mother plot skipped that rule.

Did Finding Nemo increase wild take?

Several trade analyses reported a demand spike after 2003. Captive-bred ocellaris later absorbed much of the legal market in the US and EU.

Why do anemones not sting their fish?

The fish mucus lacks the cues that trigger nematocysts, and acclimation behaviour matters. It is not a cartoon handshake.

What happens when a host bleaches?

Fish may linger on a dying anemone and then vanish from that site. Reef heatwaves are a housing crisis for the genus.

Are clownfish good parents in the film sense?

Males tend the nest of demersal eggs. The biology is paternal care, not a transoceanic search.

Money around the clownfish is regional even when the brand is global.

Figures are dated educational bands -- not live quotes and not a buying guide.

Encounter bands

Viewing / tourism (2010s band)

Ticketed

Safari, hide, cage-dive or parade tickets in the 2010s often sat in the tens to hundreds of USD per person -- a dated band, not a live quote.

Conflict / livestock loss

Local & episodic

Predation and crop-raid compensation schemes (US, Kenya, India) published per-head bands that changed with election cycles.

Fishery / take value

Commodity

Where the type is a catch (tuna, salmon, fugu), 2000s-2020s ex-vessel or auction bands were the political number -- not a supermarket tag.

Captive / zoo husbandry

Institutional

Annual keep for a large mammal or a specialist bird in AZA/EAZA reports ran to five or six figures USD in the 2010s.

Enforcement / reserve ops

Public

Ranger, observer and census costs are socialised; they do not appear on a viewing ticket.

Regions

North America

ESA listings, Parks Canada, Alaska runs and Churchill buggies are the English-language field the localLens keeps returning to.

United Kingdom and Ireland

RSPB, NatureScot, reintroductions and a dense NGO press shape how this atlas type is taught in British English.

European Union / wider Europe

Habitats Directive, IWC delegations and returning wolves sit beside UK practice without being identical.

Range-state core

The biological centre of the clownfish -- often not English-speaking -- still writes the Red List.

Australia and New Zealand

DOC, Phillip Island, Taiaroa Head and kakapo-style ICU projects are the southern English conservation dialect.

Global trade desks

CITES, ICCAT, IWC and auction houses price the animal whether or not a local language has a word for it.
