I'll Just Go For a Lie-Down

A recent study suggests that the most lethargic organisms are more likely to stave off extinction for longer than counterparts who 'burn' more energy (https://www.theguardian.com/science/2018/aug/22/forget-survival-of-the-fittest-the-laziest-will-inherit-the-earth). The study is largely based on an examination of marine invertebrates but one can see that a lower metabolic rate could well benefit animals (such as those limited to a relatively small sea) who might well find it difficult to ingest large numbers of calories.
