Sort animals into categories based on whether they have wings or not.

Explanation:
We need to sort the animals into two groups:
- with wings
- without wings

Let’s go through each animal one by one and decide:

1. eagle – a bird → has wings ✔
2. snake – reptile, no wings ✘
3. crab – crustacean, no wings ✘
4. tapir – mammal, no wings ✘
5. goat – mammal, no wings ✘
6. butterfly – insect, has wings ✔
7. seal – marine mammal, no wings ✘
8. duck – bird, has wings ✔
9. ostrich – bird (even though it can’t fly), still has wings ✔
10. tiger – mammal, no wings ✘
11. sparrow – bird, has wings ✔
12. bat – mammal, but has wing-like membranes used for flying → considered *with wings* ✔

So, animals with wings:
- eagle
- butterfly
- duck
- ostrich
- sparrow
- bat

That’s 6 animals.

Animals without wings:
- snake
- crab
- tapir
- goat
- seal
- tiger

Also 6 animals.

Now list them clearly under each heading.

Final Answer:
with wings: eagle, butterfly, duck, ostrich, sparrow, bat
without wings: snake, crab, tapir, goat, seal, tiger
