What does a salmon have in common with a man on a bicycle?

They are both Pareto-efficient. Here's a chart of cost of transport (calories/gram/km) vs weight (kg) comparing a salmon vs a bicycle vs a jet fighter etc: https://www.bike.nyc/wp-content/uploads/2017/04/efficiency-g...

When is that measuring the salmon? Surely, calories per gram per kilometer is very high if you're swimming upstream and low when you're going downstream, right? Is this when they're in the ocean phase?

Fun! But how to read the Y axis? Why does it start from 1 twice?

it's a logarithimic scale [0]

Those go 0.1, 0.2, 0.4, .. 1, 2, 4, ... 10, 20, 40...

I am guessing they printed "0.1" as ".1", and because it's a really bad scan the ".1" and "1" look identical.

I think it starts at .1 at the bottom, but the scan quality makes it difficult to discern the decimal.
