Question

which of the following adaptations is typical of marine mammals? a. thick layer of blubber b. body covered in thick fur c. webbed hands and feet d. breathing apparatus on the sides of the head please select the best answer from the choices provided

Explanation:

Marine mammals like seals and whales have a thick layer of blubber for insulation in cold - water environments. Blubber also serves as an energy reserve. Thick fur is not typical as it can become water - logged and less effective in water. Webbed hands and feet are more common in amphibians and some birds for swimming but not the most characteristic of marine mammals. Marine mammals are air - breathers and do not have breathing apparatus on the sides of the head like fish (gills).

Answer:

A. thick layer of blubber
