Orca vs Blue whale

What are they, and what does the difference actually look like?

Two things. One honest scale.

What these two things are

Orca

The orca, or killer whale, is a highly intelligent marine mammal in the dolphin family that hunts in coordinated groups.

7 mLength

Blue whale

A blue whale is a baleen whale that feeds by filtering small animals from seawater.

25 mNose-to-tail length

The nose-to-tail length of Blue whale is about 3.57 times the length of Orca.

Measurements, assumptions & sources +

Orca

A chosen 7 m, 4,500 kg killer whale. This is a toothed whale, not a blue whale.

Defined examples — our methodology

The marked length is calibrated. Unmeasured illustration details are representative.

Blue whale

A chosen 25 m, 100 tonne adult blue whale (Balaenoptera musculus). Population, sex and age matter: this is a representative comparison specimen, not a record animal.

NOAA Fisheries — Blue whale

The marked nose-to-tail length is calibrated. Unmeasured illustration details are representative.

Length ↔ Nose-to-tail length
Relative size
Blue whale is larger on this measurement by a factor of about 3.57. Blue whale's selected measurement is approximately 257% greater than Orca's.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

  • Orca is labelled defined specimen; treat the displayed value as a comparison anchor rather than false precision.
  • Blue whale is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
