Torpedo is commonly

Options

A. Suckerfish
B. Electric ray
C. Globefish
D. Sea horse

Answer

**Step-by-Step Solution:**

1. **Identify the Classification**: The first step is to classify the organism in question, which is "torpedo". It is important to note that torpedo belongs to the category of cartilaginous fish.

2. **Understand the Structure**: Recognize that cartilaginous fish have an endoskeleton made of cartilage rather than bone. This is a key characteristic that differentiates them from bony fish.

3. **Specialized Cells**: Next, we need to focus on the specialized muscle cells present in torpedo, known as electrocytes. These cells are crucial for the unique ability of torpedo.

4. **Function of Electrocytes**: Understand that electrocytes can generate electrical currents. When stimulated, these cells allow ionic movement across their membranes, which leads to the generation of electrical potential.

5. **Voltage Generation**: The electrical potential generated by these electrocytes can range from 20 to 50 volts. This is significant as it highlights the capability of torpedo to produce electric shocks.

6. **Common Name**: Finally, based on the information gathered, we conclude that torpedo is commonly known as the "electric ray." This name reflects its ability to generate electricity.

**Final Answer**: Torpedo is commonly known as the electric ray.
