A mammal in which milk is squirted down to throat of baby by muscular contraction of mother is

Options

A. Bear
B. Camel
C. Whale
D. Rhinoceros

Answer

To answer the question, "A mammal in which milk is squirted down to the throat of the baby by muscular contraction of the mother is," we can follow these steps:

### Step 1: Understand the Question
The question is asking about a specific type of mammal that has a unique method of feeding its young. We need to identify which mammal uses muscular contractions to squirt milk into the throat of its baby.

**Hint:** Focus on the feeding methods of different mammals, particularly how they deliver milk to their young.

### Step 2: Analyze the Options
The options given are:
- Bear
- Camel
- Whale
- Rhinoceros

We need to consider the characteristics of each of these animals.

**Hint:** Think about whether each of these animals is terrestrial or aquatic and how that might affect their feeding methods.

### Step 3: Identify Mammal Characteristics
All the listed animals are mammals, which means they have mammary glands that produce milk. However, the method of feeding can vary significantly between terrestrial and aquatic mammals.

**Hint:** Recall that aquatic mammals may have different adaptations for nursing their young compared to terrestrial mammals.

### Step 4: Consider Aquatic Mammals
Among the options, the whale is the only aquatic mammal. Aquatic mammals face challenges in breastfeeding due to their environment. Whales have adapted by using muscular contractions to squirt milk into their calves' mouths.

**Hint:** Think about how the physical structure of whales might influence their nursing behavior.

### Step 5: Confirm the Mechanism of Milk Delivery
In whales, the mother's abdominal muscles contract to squeeze the mammary glands, ejecting milk into the mouth of the calf. This is a unique adaptation that allows them to nurse effectively in water.

**Hint:** Consider how the anatomy of whales differs from that of terrestrial mammals regarding milk delivery.

### Conclusion
Based on the analysis, the answer to the question is that the mammal in which milk is squirted down to the throat of the baby by muscular contraction of the mother is the **whale**.

**Final Answer:** Whale
