Editing Blubber (section)

==Description==
[[Lipid]]-rich, [[collagen]] fiber-laced blubber comprises the [[Subcutaneous tissue|hypodermis]]<ref>{{cite journal |doi=10.1002/jmor.10154 |title=Blubber development in bottlenose dolphins (Tursiops truncatus) |year=2004 |last1=Struntz |first1=D.J. |last2=McLellan |first2=W.A. |last3=Dillaman |first3=R.M. |last4=Blum |first4=J.E. |last5=Kucklick |first5=J.R. |last6=Pabst |first6=D.A. |journal=Journal of Morphology |volume=259 |pages=7–20 |pmid=14666521 |issue=1|s2cid=24897702 }}</ref> and covers the whole body, except for parts of the appendages. It is strongly attached to the musculature and skeleton by highly organized, fan-shaped networks of [[tendon]]s and [[ligament]]s, can comprise up to 50 per cent of the body mass of some [[marine mammal]]s during some points in their lives, and can range from {{cvt|2|in|cm|order=flip|0}} thick in dolphins and smaller whales, to more than {{cvt|12|in|cm|order=flip}} thick in some bigger whales, such as [[Right whale|right]] and [[bowhead whale]]s. However, this is not indicative of larger whales' ability to retain heat better, as the thickness of a whale's blubber does not significantly affect heat loss. More indicative of a whale's ability to retain heat is the water and lipid concentration in blubber, as water reduces heat-retaining capacities, and lipid increases them.<ref>{{cite journal |doi=10.1016/0306-4565(95)00034-8 |title=Thermal conductivity of minke whale blubber |year=1996 |last1=Kvadsheim |first1=P.H. |last2=Folkow |first2=L.P. |last3=Blix |first3=A.S. |journal=Journal of Thermal Biology |volume=21 |issue=2 |pages=123–8}}</ref>
