Whales use fat or lipid molecules for energy and insulation.
The Beluga whale stores energy in the form of blubber, a dense fat that is also used for insulation.
Just as with other mammals, when you feed, or engorge yourself, you will gain weight, and with humpback and other whales, weight gain is in the form of blubber, which serves as an insulation, but also is caloric storage for them and gives energy. Those whales who migrate live off their blubber during the long periods of no food intake, which could be 6 months or more, depending on the whale.
All mammals, including humans, have body fat/insulation, but some have more than others (e.g., whales).
Sperm Whales
animals use different methods of insulation. most, including whales, bears, and seals have thick layers of blubber (fat) to keep heat from escaping their bodies in the cold. Other animals have thick pelts (fur) that keeps them warm throughout winter months.
A combination of size (surface area to volume) and good insulation (blubber ... fat)
Whales do not perform photosynthesis. Photosynthesis is a process carried out by plants, algae, and some bacteria to convert light energy into chemical energy. Whales are mammals and obtain their energy by consuming food.
By eating, mainly fish.
No, rabbits do not have blubber. Blubber is a thick layer of fat that some marine mammals like whales and seals have to insulate and store energy. Rabbits rely on their fur for insulation and do not have blubber.
