Turns out it was likely "soft and squishy."We all have our strengths, but unfortunately for some, being strong isn't one of them., a long-extinct ocean predator whose name translates to "weird shrimp from Canada," wasn't as powerful or strong a predator as researchers previously believed.
The belief that these Canadian predators used brute strength to crush prey "didn't sit right with me," said study lead Russell Bicknell, a postdoctoral researcher in the American Museum of Natural History's Division of Paleontology, in a"Trilobites have a very strong exoskeleton, which they essentially make out of rock," he added, "while this animal would have mostly been soft and squishy."pretty monstrous-looking.
Using a technique called finite element analysis, the researchers modeled the suspected stress and strain points on the Canadian shrimp's front appendages. They were able to conclude that these appendages, though terrifying to look at, were simply not swole enough to crack and crunch rock-like trilobite shells, further confirming the predator's newer reputation as a weakling.
Instead, the researchers explain, the squishy predators appear to have been incredibly quick and agile, swimming with their front appendages outstretched while hunting other squishy, soft-bodied creatures swimming in the ocean's water column. "Previous conceptions were that these animals would have seen the Burgess Shale fauna as a smorgasbord, going after anything they wanted to," said Bicknell, "but we're finding that the dynamics of the Cambrian food webs were likely much more complex than we once thought."
