1. Frogs and Toads: Frog and toad tadpoles are aquatic and have long tails, while adult frogs and toads are terrestrial and have no tails.
2. Butterflies and Moths: Butterfly and moth caterpillars look completely different from their winged adult forms. Caterpillars are worm-like and feed on plants, while adults have wings and feed on nectar.
3. Sea Turtles: Baby sea turtles (hatchlings) have a soft shell and are much smaller than adult sea turtles. As they grow, their shell hardens, and they can grow to be very large.
4. Salmon: Salmon hatch as small, freshwater fish called fry. They then undergo several transformations, including a process called "smoltification," before migrating to the ocean as adults.
5. Spiders: Spiderlings look similar to adult spiders, but they are much smaller and may have slightly different markings or colors.
6. Snakes: Baby snakes (hatchlings) are often much smaller than adult snakes and may have different color patterns. As they grow, their colors and patterns may change.
7. Octopuses: Octopus hatchlings are planktonic and look very different from adult octopuses. They have large heads, big eyes, and long arms but lack the distinctive body shape and tentacles of adults.
8. Eagles: Baby eagles (eagnets) have brown feathers, white tips on their wings, and a different beak shape compared to adult eagles. As they mature, their feathers become darker, and they develop the characteristic yellow beak and white head of adult bald eagles.
9. Mantises: Baby mantises (nymphs) look similar to adult mantises but are smaller and wingless. As they molt and grow, they develop wings and reach their adult size.
