Why do marine mammals spend a lot of energy producing milk for their young?

All mammals expend a significant amount of energy producing milk for their offspring. This is an evolutionary feature unique to mammals and it confers a significant benefit to the offspring - the milk is complete nutrition for the offspring, which gives the offspring better odds of surviving to reproductive age itself.

How to Stand Out from Other Budding Marine Biologists?
The ugly truth is, it can be difficult to get a job as marine biologist. Many marine biologists begin their studies hoping to study colorful marine creatures or train marine mammals. These goals are definitely attainable. However, the really interesting jobs are highly competitive. If you want to become a dolphin trainer, for example, you need experience. Yes, a degree is necessary to become a trainer, but what employers really look for is experience. While you�re working on your degree, volunteer with your local zoo or aquarium. Apply for internships that deal with marine mammals. If you can�t get an internship working with dolphins or other marine mammals, find internships or volunteer opportunities that have to do with marine life. The more time you spend gaining experience and networking in the field, the better you will look to future employers.
What animal produces few eggs and what animal produces numerous eggs?
Animals that take care of their young produce fewer eggs. e.g. crocodiles. Animals that leave their young to fend for themselves produce numerous eggs. e.g. fish. This is an energy balance. You spend little energy to produce eggs, but spend more energy taking care of your offspring. Conversely, you can spend lots of energy producing many eggs and spend little energy thereafter. It's a numbers game.
Are dolphins mammals or anphibians?
They are aquatic mammals, or marine mammals, because even though they live in they ocean, they're still warm-blooded animals (they could maintain their body temperature) and they give birth. Amphibians are cold-blooded, lays eggs, usually spend their juvenile lives in water and adult life on land, and sometimes have smooth skin.
How can Humpbacks be protected?
The best way to effectively see our humpbacks (and other marine life) protected is through education. Aquariums, schools, tours such as whale watching, can all increase awareness. There needs to be much more education on the harms of captive marine mammals as well. No whale or dolphin should be forced to spend their entire lives in a pen, fed dead food, and forced to do tricks. Marine mammals often have lifetime family bonds. To force anything less is cruel and unjust.
Is a polar bear a marine mammal or any kind of mammal?
Polar bear is definitely a mammal. Many scientists and zoos classify them as a marine mammal due to the amount of time they spend in the water swimming from ice flow to ice flow looking for seals, but they are mammals who nurse their young like any other mammal.
What are mammals that can swim called?
Most mammals are capable of swimming. The ones that spend all of their time in water are called aquatic mammals, and the ones that spend part of their time in water (such as platypuses, otters and beavers) are called semi-aquatic.
Why do mammals and birds spend a lot of time grooming their body?
So they can get laid
What opportunities are there for being a marine biologist?
you get the satisfation of helping animals and you get to spend a lot of time with them
How long can you spend in camp?
Marine Corps Boot Camp is a thirteen week ordeal.
How long can a dugong stay in the water?
Dugongs are aquatic mammals, they spend their whole life in the water.
What is cetology?
Cetology is a science, which studies eight species of whales, dolphins, and porpoises. It is a branch of marine mammal science and focuses on these larger animals. The study of cetaceans can pose many difficulties as cetaceans spend only 10% of their time on the surface. They also do not leave tracks that can be followed. Numerous times this science consists mainly of watching and waiting.
