2020年5月27日 · A giant tadpole found in the wild is bigger than a can of Coke, and it's still growing. Here's the story behind this massive weirdo, nicknamed Goliath.

Pseudis paradoxa, known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America. [2] . Its name refers to the very large—up to 27 cm (11 in) long— tadpole (the world's longest), which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length.

2021年5月6日 · An enormous tadpole found in the wild is bigger than a can of Coke — and it’s still growing. Biologists discovered the sizable swimmer in a shallow pond in southeastern Arizona; they were removing invasive American bullfrogs (Lithobates catesbeianus) with the Southwestern Research Station (SWRS), a year-round field station run by the ...

2020年6月1日 · Goliath was a bullfrog tadpole that never metamorphosed. At the time of his capture in 2018, he was larger than a soda can. Herpetologists are unsure why Goliath was stuck in tadpole limbo, but believe it is due to a hormone imbalance.

2023年12月30日 · Paradoxical frogs — also known as shrinking frogs — are about three times bigger as tadpoles as they are when adults.

2024年10月30日 · Here we describe the oldest-known tadpole from the Middle Jurassic La Matilde Formation (Bathonian–Callovian, around 168–161 million years ago (Ma)), based on a well-preserved specimen found in...

2018年6月14日 · The largest bullfrog tadpole on record was discovered by a volunteer at the American Museum of Natural History’s Southwestern Research Station in Arizona, researchers said Thursday.

Goliath was discovered in 2018, during SWRS's trip to capture American buffalo frogs (Lithobates catesbeianus) in southeastern Arizona. A volunteer sees an oversized tadpole while looking at a shallow lagoon. Goliath was so large that the volunteer initially thought it was a fish.

Pseudis paradoxa has an extremely large tadpole with a long, deep tail- These features are also found in overwintering tadpoles of temperate species where low temperatures delay development and prolong prolactin exposure. Pseudis paradoxa does not occur in localities with marked seasonal temperature fluctuations.

2009年5月19日 · Pseudis platensis, like Pseudis paradoxa, is a Neotropical aquatic frog with a giant tadpole. Despite being one of the few anuran species whose larvae grow larger than adults, knowledge...
