Specific heat has nothing to do with specific volume.
Heat does not possess a specific volume
Yes it has! the specific heat of water at constant volume is given by cV : Heat capacity at constant volume cP : Heat capacity at constant pressure : Thermal expansion coefficient : Isothermal compressibility : Density
This is the necessary heat to raise the temprataure of 1 mol with 1 kelvin, at constant volume.

The "specific heat capacity" is simply the heat capacity per unit - it might be per mass unit, per volume unit, or per amount of moles.
The high specific heat allows water to act as a heat sink. Water will retain its temperature after absorbing large amount of heat and retain its temperature after losing equally large amount of heat. So water is essential for life.
Another way to say heat capacity is thermal capacity.
Density has dimensions of: mass/volume for example: the density of water at 4 °C is 1.000 g/cm3 Specific heat has dimensions of: energy/(mass·temperature) for example: the specific heat of water is about 1 calorie/g·°C
Because water has a high specific heat content (~4200 J/kg/K ) which means it takes a lot of changes in heat (i.e. energy flux, whether it's heating from the sun, or lost of heat through latent heat flux, sensible heat flux etc) to get a degree of temperature change
Thremoregulation is easily achieved in large animal as they are able to retain the heat gained. In small animal the surface area is large as compares to their volume and hence gain or loose heat faster. large animal having smaller surface area as compared to their volume gain heat slower.
