I've had a little [bird] to say about the adverse effects of surface to volume ratio. Mammals and birds are generally homeothermic: designed to function only in a narrow range of temperatures. Small creatures, like those stormy petrels have a proportionately large surface area which is leaking heat all the time. They have, therefore, to be eating all the time to replace the lost calories. Big things otoh don't have enough surface for their bulk and have to be concerned not to over-heat. Having large ears networked with hot blood-vessels is the elephant's way of fanning off some of the excess heat. The system only really works if the skin is wet so that the latent heat of evaporation can suck heat from the body as the liquid water turns to vapour.
hot weather as their skinny cousins. otoh the thin dudes feel the cold more. You don't hear much about sealing nowadays. In the 1970s we all got exercised about the practice of clubbing baby seals to death so that rich ladies could wear naturally white fur coats. I'm assuming that doesn't go on any more in commercial quantities. After struggling through Moby Dick, many years ago, I went on a whaling reading jag and that led to the sealing 'industry'. Any industry depends for its success on efficiency. Seal hunting required a sealing ship to descend on some undisturbed rookery and have the crew kill the mostest with the leastest and load the 'product' on board. The product was threefold: skin, meat and fat. Herding the seals to a central place was more efficient than hauling dead seals to the loading point. As the terrified seals lolloped to the killing fields some would die from heat-stroke. The pragmatic sealers had an uncompassionate term for these unfortunate seals which I cannot now track down - it might have been road-kill. The point at issue being that in seal physiology, as in human ditto, the transfer of energy from glucose to muscle movement via ATP is inefficient and this is manifest as heat. The frantic seals, flooded with adrenalin, were too bulky and had too small a surface area to dissipate the heat with the physiological systems that were designed to work in Arctic waters at 5oC.
Weirdly, my thoughts on these disturbing issues were triggered by my look at another sort of maritime enterprise - cruise-ships. In retirement, my folks acquired a wide experience in that industry and they 'spent my inheritance' [and welcome to it] on almost annual cultural cruises with Swan-Hellenic. There is a limited market for spending the time between ports being lectured by a retired bishop about Byzantine triptychs and the Ἀρτεμίσιον: the great ruined temple of Artemis at Ephesus. So the Swan-Hellenic cruise-ships were quite small and pretty much everyone's cabin had a view of the heaving sea through a port-hole.
virtual balconies" connected to out-facing cameras elsewhere in the ship. Why this should be considered acceptable rather than fraudulent is a mystery to me.
lifeboats can carry 370 people. They are used as shuttles [L above] when not called upon for an emergency. In an emergency, even a traditional 150-person life-boat looks real crowded, hope they get rescued soon.
