Show Answer Key & Explanations Step-by-step solution for: Odd one out | TPT
I will solve this "Find the Odd One Out" puzzle by examining each row and identifying the item that doesn't belong with the others. I'll go through each line one by one.

Line 1:


- First, look closely: This row has four images: a fish, another fish, a whale, and a third fish.
- Analysis: Three of the images are clearly fish, which are bony or cartilaginous fish (Osteichthyes or Chondrichthyes). The third image is a whale, which is a mammal, not a fish. Whales breathe air, give live birth, and nurse their young, unlike fish.
- Conclusion: The whale is the odd one out in this row.

Line 2:


- First, look closely: This row contains four different types of underwater flora or fauna: what appears to be a sea anemone or coral, seaweed or kelp, a branching coral, and a brain coral.
- Analysis: All four items are marine organisms, but let's categorize them. The first, third, and fourth are all types of coral (cnidarians), while the second is a type of algae or seaweed (a plant-like organism).
- Conclusion: The seaweed/kelp is the odd one out because it is a plant, while the others are animals (corals).

Line 3:


- First, look closely: This row shows four items: an open clam shell with a pearl, a snail shell, a hermit crab, and a scallop shell.
- Analysis: The first, second, and fourth items are all shells (from mollusks). The third item is a hermit crab, which is an animal that uses shells for protection but is itself a crustacean, not a mollusk.
- Conclusion: The hermit crab is the odd one out because it is a living animal, while the others are empty shells.

Line 4:


- First, look closely: This row includes a clownfish, a hedgehog, a seahorse, and a crab.
- Analysis: The clownfish, seahorse, and crab are all marine animals. The hedgehog is a terrestrial mammal found on land, not in the ocean.
- Conclusion: The hedgehog is the odd one out because it is not a marine animal.

Line 5:


- First, look closely: This row has a turtle, a shrimp, a squid, and an octopus.
- Analysis: The shrimp, squid, and octopus are all cephalopods or crustaceans, which are invertebrates. The turtle is a reptile with a hard shell and is a vertebrate.
- Conclusion: The turtle is the odd one out because it is a vertebrate reptile, while the others are invertebrates.

Final Answer:


The odd one out in each line is as follows:

1. Line 1: The whale (it is a mammal, not a fish).
2. Line 2: The seaweed/kelp (it is a plant, while the others are corals/animals).
3. Line 3: The hermit crab (it is a living animal, while the others are shells).
4. Line 4: The hedgehog (it is a terrestrial mammal, not a marine animal).
5. Line 5: The turtle (it is a vertebrate reptile, while the others are invertebrates).
