The story

Māui dolphins are small enough to mistake for a child's bodyboard and live their whole lives within sight of New Zealand beaches. Net bans now cover much of their range, but toxoplasmosis washing from land and any remaining gillnetting could still tip a population that produces only a handful of calves each year.

What's killing them

  • Gillnet and trawl bycatch
  • Disease (toxoplasmosis from cat-borne runoff)
  • Tiny population
