What affects shark weight

  • Species. Sharks range from under a kilogram to many tonnes.
  • Length. Weight scales steeply with body length within a species.
  • Sex. In many species females grow larger and heavier than males.
  • Diet and region. Prey availability shapes typical adult size.
  • Age. Sharks keep growing, so older individuals tend to be heaviest.

How shark weight compares
