The ocean’s first large swimming apex predators had exceptionally rapid growth
Science China PressIn a recent paper published in National Science Review, an international team of scientists reveal how the first apex predators grew. Amplectobelua symbrachiata, an ocean-dwelling relative of modern arthropods (such as spiders, lobsters and horseshoe crabs), was among the largest animals in the ocean over 500 million years ago. Using a combination of analytical methods and collecting data from hundreds of fossil specimens from the famous Chengjiang deposits of China, the team demonstrated that the fearsome feeding appendages grew isometrically – the largest ones have the same proportions as the smallest. In addition, by looking at the size-frequency distributions of the appendages, the authors were able to demonstrate that Amplectobelua symbrachiata was an extremely active marine predator that grew more rapidly than its modern relatives.
