Sorting Animals worksheet featuring various animals and categories for classification.

Let’s go step by step to sort each animal into the correct category:
Animals with feelers, Animals with shells, or Animals with scales.

First, let’s look at each animal and think about what it has:

---

A. Crab
→ Crabs have a hard outer shell (exoskeleton). They also have antennae (feelers), but their most obvious feature for sorting here is the shell.
→ So, put A in Animals with shells.

B. Snake
→ Snakes don’t have legs, but they are covered in scales. No shell, no feelers.
→ Put B in Animals with scales.

C. Seahorse
→ Seahorses are fish — they have tiny scales under their skin (even though you can’t always see them clearly). Some might think “no scales,” but scientifically, yes — they do. Also, no shell, no feelers like insects.
→ Put C in Animals with scales.

Wait — let’s double-check seahorse: Actually, seahorses have bony plates instead of typical fish scales, but in elementary science, they’re often grouped with scaled animals because they’re fish. But let’s be precise: In many school worksheets, seahorses are considered to have scales (or scale-like armor). We’ll keep it there unless contradicted.

But hold on — maybe we should check if any other animal fits better? Let’s continue.

D. Fish (striped)
→ Fish have scales. Clear case.
→ Put D in Animals with scales.

E. Turtle
→ Turtles have a big hard shell on their back.
→ Put E in Animals with shells.

F. Cockroach (or similar insect)
→ Insects have antennae — those are called “feelers” in kid-friendly terms.
→ Put F in Animals with feelers.

G. Butterfly
→ Butterflies are insects → they have antennae (feelers).
→ Put G in Animals with feelers.

H. Ant
→ Ants are insects → they have antennae (feelers).
→ Put H in Animals with feelers.

I. Scallop (seashell)
→ This is a mollusk with a hard shell.
→ Put I in Animals with shells.

Now let’s review categories:

✔ Animals with feelers:
- F (cockroach)
- G (butterfly)
- H (ant)
→ That’s 3 animals. Good.

✔ Animals with shells:
- A (crab)
- E (turtle)
- I (scallop)
→ That’s 3 animals. Good.

✔ Animals with scales:
- B (snake)
- C (seahorse) ← Wait — is this accurate?

Hold on — let’s recheck seahorse (C).

Actually, seahorses do NOT have traditional scales. They have bony rings/plates. In many elementary curricula, they may not be classified as having “scales.” But looking at the options, we need to assign every animal.

What else could go in “scales”? Only snake and fish are clear.

We have 9 animals total. Each column has 3 boxes — so likely 3 per category.

So far:

Feelers: F, G, H → 3 ✔️
Shells: A, E, I → 3 ✔️
Scales: B, D → only 2. Need one more.

That leaves C (seahorse). Even though technically not scaled like a fish, in this worksheet context, since it’s a fish relative and often taught as having “scale-like” covering, and we NEED three in scales, we’ll put C in scales.

Alternatively — is crab sometimes considered to have “scales”? No, crabs have exoskeleton/shell.

Is turtle ever considered scaled? Some turtles have scutes (which are like scales), but again, primary feature is shell.

Best fit: Since seahorse is a fish, and fish = scales in basic bio, we’ll include it.

Final assignment:

Animals with feelers: F, G, H
Animals with shells: A, E, I
Animals with scales: B, C, D

Yes — that uses all 9, 3 per group.

Double-check:

- Feelers: insects → ant, butterfly, cockroach → correct.
- Shells: crab (exoskeleton counts as shell in kids’ bio), turtle (obvious), scallop (mollusk shell) → correct.
- Scales: snake (reptile scales), fish (fish scales), seahorse (fish family, accepted as scaled in this level) → acceptable for grade level.

All set.

Final Answer:
Animals with feelers: F, G, H
Animals with shells: A, E, I
Animals with scales: B, C, D
