Name the cnidoblast bearing ctenophore

Options

A. Pleurobrachia
B. Ctenoplana
C. Euchlora
D. Cestum

Answer

To solve the question "Name the cnidoblast bearing ctenophore," we will follow these steps:

### Step 1: Understand the Terms
- **Cnidoblast**: These are specialized cells found in certain marine animals, particularly in the phylum Cnidaria. They contain nematocysts, which are stinging organelles used for defense and capturing prey.
- **Ctenophore**: This refers to members of the phylum Ctenophora, commonly known as comb jellies. They are gelatinous marine animals that are distinct from jellyfish (which belong to Cnidaria).

### Step 2: Identify the Options
The options provided are:
1. Plurobrachia
2. Tinoplanar
3. Euchlura
4. Sestum

### Step 3: Analyze Each Option
- **Plurobrachia**: This is a genus of ctenophores known as comb jellies.
- **Tinoplanar**: This does not correspond to any known ctenophore or cnidoblast-bearing organism.
- **Euchlura**: This is a ctenophore that is known to have cnidoblasts.
- **Sestum**: This is another genus of ctenophores, but it is not specifically known for having cnidoblasts.

### Step 4: Determine the Correct Answer
From the analysis, **Euchlura** is identified as the ctenophore that bears cnidoblasts.

### Final Answer
The cnidoblast bearing ctenophore is **Euchlura**.
