The newly discovered muscle layer runs from the back of the cheekbone to the anterior muscular process of the lower jaw. (S= superficial layer, D= deep layer, C= coronoid layer). Credit: Jens. C. Türp, University of Basel / UZB Human anatomy still has a few surprises in store for us: researchers at the University of Basel have discovered a previously overlooked section of our jaw muscles and described this layer in detail for the first time. The masseter muscle is the most prominent of the jaw muscles. If you place your fingers on the back of your cheeks and press your teeth together, you’ll feel the muscle tighten. Anatomy textbooks generally describe the masseter as consisting of one superficial and one deep part. Now, researchers led by Dr. Szilvia Mezey from the Department of Biomedicine at the University of Basel and Professor Jens Christoph Türp from the University Center for Dental Medicine Basel (UZB) have described the structure of the masseter muscle as consisting of an additional third, even deeper layer. In the scientific journal Annals of Anatomy, they propose that this layer be given the name Musculus masseter pars coronidea – in other words, the coronoid section of the masseter – because the newly described layer of muscle is attached to the muscular (or “coronoid”) process of the lower jaw. The anatomical study was based on detailed examination of formalin-fixed jaw musculature, computer tomographic scans and the analysis of stained tissue sections from deceased individuals who had donated their bodies to science. This was in addition to MRI data from a living person.  As if a new animal species had been discovered “This deep section of the masseter muscle is clearly distinguishable from the two other layers in terms of its course and function,” explains Mezey. The arrangement of the muscle fibers, she says, suggests that this layer is involved in the stabilization of the lower jaw. It also appears to be the only part of the masseter that can pull the lower jaw backwards – that is, toward the ear. A look at historical anatomy studies and textbooks reveals that the structure of the masseter muscle has already raised questions in the past. In a previous edition of Gray’s Anatomy, from the year 1995, the editors also describe the masseter muscle as having three layers, although the cited studies were based on the jaw musculature of other species and partly contradicted one another. Other individual studies from the early 2000s also reported three layers, but they divided the superficial section of the masseter into two layers and agreed with standard works in their description of the deeper section. “In view of these contradictory descriptions, we wanted to examine the structure of the masseter muscle again comprehensively,” says Türp. “Although it’s generally assumed that anatomical research in the last 100 years has left no stone unturned, our finding is a bit like zoologists discovering a new species of vertebrate.” Reference: “The human masseter muscle revisited: First description of its coronoid part” by Szilvia E.

A new study found that smaller Antarctic minke whales would not be able to survive, as they would not capture enough food using the lunge-feeding method of baleen whales. Minke whales are as small as a lunge-feeding baleen whale can be. Research on the feeding behavior of Antarctic minke whales found that a smaller whale could not capture enough food to survive using the lunge-feeding strategy of baleen whales. A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient “lunge-feeding” strategy that enabled the blue whale to become the largest animal on Earth. Lunge feeding whales accelerate toward a patch of prey, engulf a huge volume of water, and then filter out the prey through the baleen plates in their mouths. This strategy is used by the largest group of baleen whales, known as rorquals, which includes blue, fin, humpback, and minke whales. Baleen whales, also known as mysticetes, are a type of marine mammal that have a comb-like structure called baleen plates in their upper jaw instead of teeth. They use these baleen plates to filter out small prey, such as krill and plankton, from the water as they swim with their mouths open. Besides for minke whales, other xamples of baleen whales include humpback whales, blue whales, and gray whales. The ability to engulf large amounts of prey-laden water is essential to making this feeding strategy pay off, and the energy efficiency increases with larger body size. An 80-ton blue whale, for example, can engulf a water volume equivalent to 135% of its body mass, whereas a 5-ton minke whale can engulf a volume equal to 42% of its body mass. Minke whales are the smallest of the rorqual group of baleen whales, which use a “lunge feeding” strategy to capture large amounts of small prey such as krill. Credit: Duke Marine Robotics and Remote Sensing The Minimum Size Threshold In the new study, published today, March 13, in the journal Nature Ecology & Evolution, researchers used noninvasive suction tags to observe 23 Antarctic minke whales in the waters off the West Antarctic Peninsula, tracking their daytime and nighttime foraging behavior as they fed on Antarctic krill. Data from previous studies of krill-feeding humpback whales and blue whales were used for comparison. “When we calculate how much energy they use in foraging and what their overall intake should be based on their size, we find that minke whales are right at the threshold,” said first author David Cade, who led the study as a postdoctoral researcher at UC Santa Cruz and is now at Stanford’s Hopkins Marine Station. “Anything smaller than a minke could not achieve the foraging rates necessary to survive.” Minke whales are not as well studied as other species of baleen whales, in part because they can be harder to find and tag.

Krill come to the surface at night and stay in the depths during the day, so daytime feeding requires deep dives, which are less efficient for smaller animals. “During the day they feed at depths comparable to humpbacks and blue whales, but their foraging rates aren’t as high because they’re smaller,” Cade said. “Their nighttime feeding rates are two to five times the day rate.” At night, the smaller, more maneuverable minke whales are well suited for pursuing small, scattered patches of krill at the surface. “When they’re surface feeding, they don’t have to hold their breath during dives and they can do lunges over and over again,” Cade said. “Only at night can they get the really high feeding rates they need.” Evolutionary Insights into Baleen Whale Sizes The study also addresses questions about the evolution of baleen whales and the origins of a feeding strategy that depends on large body size. Lunge feeding is thought to have arisen first in whales about the size of today’s Antarctic minke whales. This enabled the evolution of whales with gigantic body sizes, such as blue whales, during the past 5 million years when changing ocean conditions led to the formation of predictable regions with large prey patches that could be efficiently exploited by lunge-feeding whales. “Minke whales represent one extreme, at the small end of the spectrum, for how filter feeding in ocean predators evolved,” Friedlaender said. “Understanding both the maximum and minimum size constraints on baleen whale size really helps us understand how this group of animals has evolved and how they affect and are impacted by marine ecosystems.” Reference: “Minke whale feeding rate limitations suggest constraints on the minimum body size for engulfment filtration feeding” 13 March 2023, Nature Ecology & Evolution.

The drill holes found in shells show the clearest, most complete form of predator/prey interaction found in the fossil record. Credit: Florida Museum photo by Kristen Grace Marine predators and the prey they prefer are both declining. Had you stopped monitoring the marine life of the Adriatic Sea in the mid-20th century, the prospects would have seemed bright. Throughout the late 1800s and early 1900s, both snails and the clams they prey on thrived, indicating a robust and healthy ecosystem. Then, a threshold was crossed. Populations of both predator and prey abruptly plummeted and in some cases disappeared entirely. They were replaced by the common corbulid clam (Varicorbula gibba), which has the ability to slow down its metabolism in unfavorable conditions. Whenever paleontologists find an abundance of this species in the marine fossil record, it often means the environment they inhabited was challenging and unsuitable for other organisms. Impacts of Human Activity on Marine Ecosystems “This species became more abundant and grows much larger than it did previously because there are fewer predators and less competition from other species,” said Martin Zuschin, a paleontology professor at the University of Vienna. He and colleagues from Slovakia, New Zealand, Austria, Italy and the United States have published a new study documenting the decline of predator/prey interactions in the Adriatic Sea. The findings add to a growing body of evidence that shows human activity has dangerously destabilized marine environments in the region. The rapid increase in fishing, bottom-trawling, nutrient runoff, the introduction of invasive species, and warming water temperatures caused by climate change have radically altered marine animal communities along parts of the Italian peninsula. “From our research in the northern Adriatic Sea, we can say that species composition in these environments is much simpler than it used to be. In many places today, we’re lacking predators, grazers and organisms that live on top of the sediment, while other species, like deposit feeders and animals that live in the sediment, have become more abundant,” Zuschin said. For a more familiar land-based analog, the northern Adriatic has essentially become the marine equivalent of a golf course, with low biodiversity and excess nutrients. Zuschin and his colleagues have studied the Adriatic’s deterioration for several years by comparing the organisms that currently live there with fossils from those that existed before the arrival of humans in the region. Conservation Paleobiology and Species Interactions This type of research, called conservation paleobiology, allows scientists to measure declines in biodiversity and make informed recommendations on how to restore natural areas. The authors of the current study had the rare opportunity to go a step further. Instead of looking only at declines in the number of individuals and species, they could determine whether the interactions between species were affected as well. This task is virtually impossible with most types of fossils. Physical damage, like bite marks, can be used to study ancient scuffles between predator and prey, but paleontologists seldom find such fossils, and when they do, it can be extraordinarily difficult to determine the type of animal that inflicted the wound. Seafloor environments are one of the only exceptions to this rule. For as long as there have been marine invertebrates that produce protective outer shells, there have been predators with the ability to bore through them. A variety of marine snails, worms, and even octopi have evolved structures to grind and pulverize shells. “Some snails have specialized organs that secrete acid to soften the calcium carbonate in shells. This makes the drilling process more efficient,” said co-author Michal Kowalewski, the Thompson chair of Invertebrate Paleontology at the Florida Museum of Natural History. The circular holes left behind are a calling card, which scientists use to quantify predation. Research Methodology and Findings The researchers took samples from two regions, one in the northwest Adriatic along the mouth of the Po River and another in the northeast Gulf of Trieste. At each site, they extracted sediment cores from the seafloor using long, cylindrical tubes. Sediment near the top was younger and had settled onto the seafloor more recently than sediment at the bottom of the tube. Both locations showed the same pattern. The abundance of predators and prey along with the frequency of drill holes remained consistent until the mid-19th century, when all three spiked. Zuschin says this brief window of frenetic activity is a signature from the early days of Italian industrialization. “A moderate increase in nutrient input is good for the ecosystem,” he said. But this grace period didn’t last long. Excess nutrients in the Adriatic fueled the growth of algae, which sank to the seafloor when they died. Bacteria that degraded the dead algae used up much of the dissolved oxygen in the water, which suffocated nearby marine organisms. “It simply became too much, and the whole system crashed,” Zuschin said. These periods of low oxygen, called eutrophication, weren’t detrimental to everything, though. They may have been beneficial for the common corbulid clam, Kowalewski said. “They’re less vulnerable to lower oxygen levels than some of their competitors, and they can proliferate quickly.” Corbulid clams also don’t seem to be a favored food source for drilling predators. Their shells are occasionally found with tell-tale holes in them, but at a lower frequency than other species. With their only limitation being how much they can eat, corbulid clams have thrived in the denuded waters of the northern Adriatic. And there’s another problem lurking on the horizon. Climate change is heating up the Adriatic, which means its water is becoming more stratified. This happens when increasingly warmer water on top mixes less with the colder water below, impeding the flow of oxygen from the surface to lower depths. In areas where eutrophication is already a problem, things are likely going to get worse. Still, Zuschin says, there’s reason to be optimistic. Efforts are underway to reduce the amount of pollution that makes its way into Italy’s rivers, and samples from one location in the Po River Delta even show a small uptick in drill-hole frequency. Zuschin also warns that restoration won’t be easy and will only get harder the longer it gets put off. “Environmental degradation is extremely expensive. You cannot even quantify it, because something that is gone that had a tremendous impact on the quality of life cannot be accounted for in terms of money.” Reference: “Human-driven breakdown of predator–prey interactions in the northern Adriatic Sea” by Martin Zuschin, Rafał Nawrot, Markus Dengg, Ivo Gallmetzer, Alexandra Haselmair, Michał Kowalewski, Daniele Scarponi, Sandra Wurzer and Adam Tomašových, 1 September 2024, Proceedings of the Royal Society B.
