Lurking creature — with more than 200 legs — found as new species in Thailand
The tiny island of Ko Phayam in the Andaman Sea off the coast of Thailand is home to picturesque beaches and cashew plantations.
Just a few miles across, the island is a tourist stop along the country's west coast.
It's also home to a new species.
Researchers on the island in 2022 looked around the bases of trees when they saw a creature lurking beneath the leaves, according to a study published June 6 in the peer-reviewed journal Zoological Science.
Brown millipedes were 'found crawling and hiding underneath leaf litter of coconut trees, jackfruit trees and other native vegetation,' researchers said.
The animals belonged to the genus Thyropygus, but a DNA analysis showed they were a species never seen before, according to the study.
Thyropygus payamense, or the Payam (Phayam) Island millipede, is between 4.7 and 5.5 inches long, depending on the sex, researchers said.
Their bodies are made from about 60 podous rings, or body segments that nestle together and allow the millipede to move and curl into a spiral shape, according to the study.
Each podous ring is attached to four legs, meaning the animals have about 240 legs down the length of their bodies.
'Overall color of living animal (is) dark brown,' researchers said. The antennae, legs and other small appendages are 'reddish brown.'
The species is differentiated from known millipedes by a 'small, slender pointed spine' on the base of a feature of the leg, which isn't found on other members of the genus, according to the study.
'The millipede genus Thyrophygus, (first described by) Pocock (in) 1894, is widely distributed across Thailand and Southeast Asia and currently comprises 67 recognized species, 46 of which are exclusively found in Thailand,' researchers said.
Millipedes are not insects, but rather more closely related to animals like lobster, shrimp and crayfish, according to the National Wildlife Federation. The name 'millipede' directly translates to 'a thousand feet,' but no species has been found with quite that many.
Millipedes consume organic matter and break down dead plant material that is then returned to the soil, bringing nutrients back into the landscape similar to worms, the National Wildlife Federation said.
Ko Payam (Phayam Island) is off the western coast of Thailand, just south of the southern tip of Myanmar.
The research team includes Piyatida Pimvichai, Henrik Enghoff, Karin Breugelmans, Brigette Segers and Thierry Backeljau.

Researchers uncover wildfire protection strategy hiding in plain sight — and it starts with an overlooked species
Beavers are offering forests unexpected protection against wildfires. By bolstering beaver habitats, scientists have found they can prevent parts of the environment from being scorched. A new study shows that beaver dams and the wetlands they create were the only features to survive an incinerated landscape in the wake of recent wildfires in Colorado. In 2020, the East Troublesome Fire became the second-largest wildfire in the state's history, burning nearly 200,000 acres and taking more than a month to contain. While assessing the damage from the fire, wildlife managers reported that only beaver ponds were untouched. Beavers are incredible creatures, building dams to create their own habitat. The semiaquatic rodents block off streams to pool water into ponds and develop wetlands where they can build homes. The water, of course, is not flammable and offers protection against an increasing number of wildfires. Researchers studied five fires from 2000 to 2018. In their findings, they reported that beaver ponds and canals thoroughly irrigate the surrounding land, turning dry, flammable vegetation into lush landscape. Not only did the plants survive, but the green space provided refuge to livestock and wildlife. Wildfires impact human communities in a number of ways. Smoke inhalation increases the risk of heart attack and stroke while reducing the body's immunity. Wildfires also have an effect on mental health, causing trauma when a person is exposed to danger and loss. Wildlife managers are looking for ways to support beaver populations. It's estimated that while there were once 100 to 200 million beavers across North America, today's numbers sit around 10 to 15 million. The U.S. Fish and Wildlife Service is focusing on habitat restoration. In 2018, the National Wildlife Federation adopted a resolution to support beaver restoration as a response to the changing climate. Beavers are often called nature's engineers. Their ingenuity could be the answer to surviving in a world with an ever-changing climate. What would you do if natural disasters were threatening your home?

Cicada maps show where the insects will emerge in the U.S. this spring
Cicadas are poised to return at some point in the spring of 2025, potentially bringing billions of bugs to neighborhoods across the eastern United States. The group of cicadas set to appear has been labeled Brood XIV. Emerging once every 17 years, Brood XIV is the second-largest group of periodical cicadas — which rise from underground en masse — and will be the only group this spring. That means there will likely be fewer cicadas above ground than there were in 2024, when multiple broods of cicadas emerged at the same time. Where will cicadas emerge in spring 2025? Cicadas this year will likely be concentrated in Kentucky and much of Tennessee. The insects from Brood XIV are also expected to show up in parts of Georgia, Illinois, Indiana, North Carolina, Virginia and West Virginia, in addition to smaller pockets farther north in Cape Cod, Massachusetts, central Pennsylvania and Long Island, New York. CBS News' data team created an interactive map that shows where cicadas are expected to be this year. The map uses information from the University of Connecticut's Cicada Project, which plots the brood's spread based on its known locations in the past. When will cicadas emerge in spring 2025? The huge groups of cicadas emerge when the soil reaches a certain temperature in the spring, according to University of Connecticut researchers. In warmer states, cicadas usually come out in late April or May. In cooler states, their arrival tends to occur in May or early June. How long will cicadas be above ground? Researchers say cicadas typically remain in a given area for 4 to 6 weeks after they first emerge. Most individual cicadas live for just a few weeks, but, since the emergence itself happens over a two-week period, their eventual fading will also be staggered. What are cicadas? Cicadas are a type of insect, related to stink bugs, bed buds and aphids. The ones expected to arrive in droves this year are a variety called periodical cicadas, which appear in huge swarms and often create loud buzzing sounds, according to the National Wildlife Federation. Annual cicadas exist as well. Periodical cicadas have earned a reputation across eastern North America because of their conspicuous recurrence. Individual "broods" are biologically synchronized to crop up simultaneously in 13- or 17-year intervals, when they rise from their burrows underground in populations that can reach up to the trillions. Between intervals, they live in soil as larvae and feed on fluids from plant roots, the wildlife federation explains. There are three species of cicadas that emerge every 17 years, and four species that materialize every 13 years, according to researchers at the University of Connecticut. When cicadas share the same emergence year, they're considered part of a brood. The interactive map below shows where different broods are scattered across the country. { font-family: "Proxima Nova"; font-size: 16px; display: inline-block; margin-right: 10px; } .select-container { display: flex; align-items: center; } .embed__resizer { padding-top: 650px !important; } /* Default height for larger screens */ #datawrapper-chart { width: 100%; height: 650px; border: none; } @media (max-width: 768px) { .embed__resizer { padding-top: 550px !important; } } @media (max-width: 480px) { .embed__resizer { padding-top: 400px !important; } /* Adjust height for mobile screens */ @media (max-width: 480px) { #datawrapper-chart { height: 350px; } } } Active periodical cicada broods in the U.S. Select a brood: All broods Brood I (2029) Brood II (2030) Brood III (2031) Brood IV (2032) Brood V (2033) Brood VI (2034) Brood VII (2035) Brood VIII (2036) Brood IX (2037) Brood X (2038) Brood XIII (2041) Brood XIV (2025) Brood XIX (2037) Brood XXII (2027) Brood XXIII (2028) Your browser does not support embedding this content. function switchVis(chartId) { = ' + chartId; } Why do cicadas make noise? The noise people often hear from cicadas is a mating tactic, according to the wildlife foundation, which notes that male cicadas tend to crowd together and produce raucous choruses in efforts to attract females. Once the mating process has ended, female cicadas deposit their eggs in tree branches. When they hatch, the larvae fall to the ground, burrow into the soil, and the cycle starts again.
