A new review paper on the muscular adaptations for generating high power, explaining why the pectoral muscles of the blue-breasted quail generate the highest power per kg https://t.co/7F8XgRgI9T

New paper out (+ check out the JEB cover!) - Mechanics of cuttlefish mantle muscle - we found muscle contraction kinetics slow during development w this underlying the shift in optimal frequency for maximal power output during jet propulsion swimming https://t.co/zOhbYIGslS

@JohnAltringham @BanksideGallery @woodengravers Congratulations John! I can see why, it’s wonderful!

From the moth trap this morning - a poplar hawkmoth and a brimstone moth.

Hawkmoths caught in the garden last night - a lime hawkmoth and an elephant hawkmoth. Quite tricky to photograph as they were blowing in the wind and shivering to warm up their flight muscles!

@JohnAltringham I’m sure we will run into each other at some point up there! I was hunkered down behind a rock waiting for the sunlight to go in the right spot for a while.

Blue-blubber jellyfish have a relatively high propulsive efficiency compared with other swimmers, which they achieve by manipulating the water around them with their flexible bodies

@JohnAltringham I don’t have his book but I do have ‘Autumn Langdales’ on my wall!

The nautilus is a highly efficient jet-propelled creature, wasting much less energy than marine organisms like squid or jellyfish https://t.co/ILQ114N0Q7

Forget fish fins. The chambered nautilus speeds through the ocean on little jets of water like a tiny submarine. https://t.co/AqP0jnu1yQ
