The task in the image is to classify whales into two main categories: Baleen Whales and Toothed Whales. Let's solve this step by step.

🐋 Understanding Whale Classification

Whales are divided into two primary groups based on their feeding mechanisms:

1. Baleen Whales (Mysticetes)
- Have baleen plates instead of teeth.
- Use baleen to filter small prey like krill and small fish from water.
- Typically large, have two blowholes, and no dorsal fin (in some species).
- Examples: Blue Whale, Humpback Whale, Gray Whale.

2. Toothed Whales (Odontocetes)
- Have teeth for catching prey (fish, squid, seals, etc.).
- Use echolocation to navigate and hunt.
- Usually smaller than baleen whales (though sperm whale is large), have one blowhole, and often have a dorsal fin.
- Examples: Killer Whale, Sperm Whale, Narwhal.

✔ Step-by-Step Sorting

Now, let’s go through each whale in the image and classify it:

#### Baleen Whales (Mysticetes) – These have baleen plates (no teeth):
- Gray Whale – Yes, baleen whale.
- Bowhead Whale – Yes, baleen whale (large, no teeth).
- Blue Whale – Yes, largest animal, baleen.
- Humpback Whale – Yes, has baleen.
- Right Whale – Yes, baleen whale.
- Fin Whale – Yes, baleen.
- Sei Whale – Yes, baleen.

✔ Baleen Whales List:
- Gray Whale
- Bowhead Whale
- Blue Whale
- Humpback Whale
- Right Whale
- Fin Whale
- Sei Whale

#### Toothed Whales (Odontocetes) – These have teeth:
- Killer Whale (Orca) – Yes, toothed whale (even though it's large, it hunts with teeth).
- Minke Whale – Yes, toothed whale (smaller, but has teeth).
- Sperm Whale – Yes, has large teeth; famous for its huge head.
- Pilot Whale – Yes, toothed whale.
- Narwhal – Yes, toothed whale (has a long tusk, which is an elongated tooth).

✔ Toothed Whales List:
- Killer Whale
- Minke Whale
- Sperm Whale
- Pilot Whale
- Narwhal

🧩 Final Answer: Classification

#### Baleen Whales:
- Gray Whale
- Bowhead Whale
- Blue Whale
- Humpback Whale
- Right Whale
- Fin Whale
- Sei Whale

#### Toothed Whales:
- Killer Whale
- Minke Whale
- Sperm Whale
- Pilot Whale
- Narwhal

💡 Tips for Students:

- Look for baleen plates (shown as fringes inside mouth) — these are only in baleen whales.
- Teeth or tusks indicate toothed whales.
- Blowhole count: Baleen whales usually have 2 blowholes; toothed whales have 1.
- Dorsal fin: Present in many toothed whales, absent in some baleen whales (e.g., blue whale).

This classification helps students understand how whales evolved different feeding strategies and adapt to their environments. 🐋💙
