A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails.
Triops longicaudatus (commonly called American tadpole shrimp or longtail tadpole shrimp) is a freshwater crustacean of the order Notostraca, resembling a miniature horseshoe crab. It is characterized by an elongated, segmented body, a flattened shield-like brownish carapace covering two thirds of the thorax, and two long filaments on the abdomen.

The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds.

The eggs are laid in temporary ponds that may quickly evaporate, so the tadpole stage is unusually brief, with rapid development to the adult form in as little as two weeks. To further speed their growth, some of the tadpoles are cannibalistic, eating their brood-mates to increase their supply of protein. [2]
The tadpole madtom has a dark brown back with a lighter brown color on their sides and a yellow or white stomach. The pelvic and pectoral fins of adults are heavily covered in melanophores responsible for pigmentation, and the dorsal and anal fins contain fewer melanophores. There are also bands of melanophores on both the upper and lower jaws ...
The disturbingly-named “tadpole water” drink. No, this isn’t frogspawn from your local pond—it’s a drink made by mixing chia seeds into water with a squeeze of lemon juice.
Due to their high levels of activity, squirrel tree frogs tadpoles are vulnerable to predation by multiple species of fish, and the adults are vulnerable to predation by the non-native Cuban tree frog. [15] [16] Because of their rapid growth and development, the tadpoles are more likely to survive insect predators than fish predators. [13]
