Let’s go step by step through each sentence and match it with the correct word from the list on the left.

We are given a word bank:
- C: coral
- crab
- E: eel
- F: fish
- J: jellyfish
- L: lobster
- O: octopus
- P: plankton
- S: seahorse (already used in #1)
- seal
- sea turtle
- shark
- shellfish
- starfish
- W: whale

Now, let’s solve each one:

---

2. Tuna, cod, and salmon are kinds of ________.
→ These are all types of fish.
✔ Answer: fish

---

3. A ________ is very large and it looks like a big fish, but it isn’t a fish. It breathes air.

✔ Answer: whale

---

4. A ________, of course, looks like a star.
→ Starfish! The name says it all.
✔ Answer: starfish

---

5. An ________ looks like a snake, but it’s a fish.
→ Eels look like snakes but are fish.
✔ Answer: eel

---

6. ________ are very brightly colored animals that live in the ocean – and they look like plants!
→ Coral often looks like colorful underwater plants.
✔ Answer: coral

---

7. ________ are ocean plants and animals that are so small you need a microscope to see them!
→ Plankton are tiny organisms floating in the ocean.
✔ Answer: plankton

---

8. Most people are very afraid of ________ because they can be very dangerous.
→ Sharks are often feared for being dangerous.
✔ Answer: sharks *(Note: “shark” is listed as singular, but sentence uses plural verb “are” — wait, no: sentence says “afraid of ________s” — actually, looking back: original says “afraid of ________s”? Let me check the image text again... Actually, in the user’s transcription, it says: “Most people are very afraid of ________s because...” — but in the actual worksheet, it might just say “________”. Wait — looking at the original problem statement provided by user: “8. Most people are very afraid of ________s because they can be very dangerous.” — Hmm, but in the word bank, we have “shark n.” — singular. But the blank has an ‘s’? Actually, rechecking the user’s input: In their typed version, they wrote: “8. Most people are very afraid of ________s because...” — but in the real worksheet image description, it may not have the ‘s’. Since this is a fill-in-the-blank, and the word bank gives “shark”, and the sentence likely expects “sharks” (plural), but since the instruction says to use words from the left, and “shark” is listed, we’ll assume the blank is for the base word, and the ‘s’ is part of the sentence structure. So we put “shark” and the sentence becomes “afraid of sharks” — which makes sense. Alternatively, maybe the worksheet doesn’t have the ‘s’ — but based on standard usage, we’ll go with “shark” as the answer, understanding it implies plural. To be safe, let’s note: if the blank includes the ‘s’, then we still write “shark” because that’s the root word given. But actually, looking again at the user’s transcription: they wrote “________s” — meaning the blank is before the ‘s’. So we should write “shark” → making “sharks”. Yes. ✔ Answer: shark

Wait — correction: The user wrote: “8. Most people are very afraid of ________s because...” — so the blank is followed by an ‘s’. That means we fill in the singular form, and the ‘s’ makes it plural. So “shark” + “s” = “sharks”. Perfect. So answer is shark.

9. A ________ looks a little like a spider.
→ Octopuses have many legs and can resemble spiders. Also, sometimes people compare them to spiders. Jellyfish don’t really look like spiders. Lobsters? No. Crab? Maybe, but octopus is better fit. Also, clue #14 mentions eight legs — that’s octopus too. But here, “looks like a spider” — octopus is commonly compared to spider due to multiple arms/legs.
✔ Answer: octopus

But wait — let’s hold off and check #14: “An ________ has eight legs and it has a soft body. It’s not a jellyfish.” → That’s definitely octopus. So #9 might be something else? What looks like a spider? Maybe crab? Crabs have claws and legs, somewhat spider-like. Or even lobster? But octopus is more famously compared to spider. However, since #14 clearly points to octopus, perhaps #9 is crab? Let’s think.

Actually, some sources say crabs are sometimes called “sea spiders” informally, but technically sea spiders are different creatures. Given the options, and since octopus is taken by #14, maybe #9 is crab? But let’s read carefully.

Alternative: Could it be jellyfish? No, jellyfish don’t look like spiders. Starfish? No. Seahorse? No.

Wait — perhaps I made a mistake. Let’s list what’s left after assigning others.

Maybe #9 is crab? Crabs have a round body and legs sticking out — could resemble a spider. And #15 says: “A ________ looks a little like a crab, but it has a longer body.” → That would be lobster. So if #15 is lobster, then #9 could be crab.

Yes! That makes sense.

So revise:

#9: Looks like a spider → crab (because crabs have multiple legs and a central body, similar to spider shape)

#14: Has eight legs, soft body → octopus

#15: Looks like crab but longer body → lobster

That fits better.

So update:

✔ #9: crab
