Study Reveals the Beach Habits Americans Don't Want to Admit Out Loud
Millions of Americans hit the beach each year, and with that many people, some bad behavior is inevitable. But just how much poor behavior goes down may surprise you. According to a recent study from 93 percent off beachgoers claim "to practice good beach etiquette, yet almost everyone (92 percent) also admits to at least one bad beach habit." The study surveyed 1,000 people, analyzing both how people think they behave at the beach and how they actually do. The three "most shameless beach behaviors" Americans engage in, according to the site, are taking sand or shells, peeing in the water, and drinking alcohol. In fact, a whopping 70.1 percent of people admit to peeing in the water (and that's just those willing to admit it), while nearly half (48.6 percent) say they consume alcohol on the beach, and 38.6 percent admit to taking shells home. While all these behaviors aren't necessarily great, taking shells from the beach could be the most detrimental of all. According to a 2014 study, tourists removing shells from popular beaches have led to "habitat changes such as increased beach erosion, changes in calcium carbonate recycling, and declines in diversity and abundance of organisms, which are dependent on shell availability." "Molluscan shells are of prime importance to hermit crabs, and although sand beaches are not good places for such crabs, dead snail shells on mud-flats and rocky shores do form a primary resource for abundant hermit crabs," Geerat Vermeij, a mollusk shell expert and distinguished professor of geology with the University of California Davis, said in response to the study. "More subtly, many small organisms settle on dead shells, and so removing such shells will eliminate habitats for these colonists." Other bad habits to make list included taking too long in the facilities, loud music, not picking up after pets, littering, smoking, feeding wildlife, and sitting too close to your neighbor. To make matters worse, the team also polled people on what behaviors annoy them most about other beachgoers. And it turns out, we're all living in glass houses, throwing stones. "Americans quietly admit to their bad beach etiquette, but they're much more vocal about the bad etiquette of others. We also appear to be a bit hypocritical," the company shared in their findings. "Even though 93 percent of the country thinks they have good beach etiquette, 92 percent also admit to at least one bad beach behavior. Here is the hypocrisy—a whopping 70 percent also say poor etiquette negatively impacts their time at the beach." Luckily, there is something we can do about it: Simply do better for our environment and fellow travelers. Pick up after your pet, wear headphones if you want to listen to music, give each other space, pee in the bathrooms when you can, and always leave the beach exactly how you found it. That way, everyone can enjoy its splendor too.

WA hermit crab exporter Merv Cooper rejects exploitation claims
A West Australian who holds one of five licences to collect and sell thousands of hermit crabs as pets has rejected criticism he is exploiting and endangering the crustacean's population. Rockingham-based store owner Merv Cooper is one of five operators with a commercial fishing licence in WA's only hermit crab fishery, which spans more than 1,500 kilometres from Exmouth Gulf in the Pilbara to Kununurra in the Kimberley. For almost 50 years, from an idea that came to him when he was a Broome pearl diver, Mr Cooper has distributed Coenobita variabilis, land crabs in Australia and overseas, with international export numbers on previous permit declarations capped at 20,000 crabs per year. But his international export licence, which expired in December, is up for renewal by the federal Department of Climate Change, Energy, Environment and Water (DCCEEW). The store owner's proposal was open for public consultation for four weeks and caught the eye of conservation groups and the Animal Justice Party. They say Mr Cooper is exploiting the species and the proposal should be rejected. Mr Cooper said the criticism was unfounded. Mr Cooper said claims he was exceeding crab collection limits were wrong. "It's just the fact we've been operating for so long," he said. "There're three or four people in Perth that want to bring it to light that we've taken too many crabs from the places we go to. "There are millions of crabs. Mr Cooper said during a two-night trip, he could collect about 2,000 crabs in one location and only took crabs a "few times" a year for exporting. Total harvest numbers are not published due to the limited number of operators in the hermit crab fishery. Mr Cooper's proposal stated that if approved, he "could" take an average of 30,000 crabs a year, but would need to access new locations. The low price, about $5 for a small crab, makes them an ideal first pet for children and families. The Animal Justice Party (AJP) and WA's Conservation Council said not enough was being done to monitor crab numbers. AJP MP Amanda Dorn said she was firmly against the proposal, despite past international export approvals. "We think this is ecologically irresponsible and ethically indefensible," she said. "The underrated hermit crab has been largely ignored for many years ... (they are) being used as a 'throw away pet'. Conservation Council WA executive director Matt Roberts said Mr Cooper's proposal should be rejected because it increased the number of crabs he wanted to export. "It is a substantial increase and that would have a material impact on some of those ecosystems," he said. Broome resident Taryn Ryan operates education seminars and walking tours to find and identify shells on Kimberley beaches. She wants fauna studies into the impact on the region. "How are we going to know if the taking of hermit crabs is going to affect the crab population? We don't," she said. "[We could] even use this as an education opportunity. "Maybe we can participate and make sure it's done in the safest way possible." The Department of Primary Industry and Regional Development, which grants the commercial fishing licences, said there were no "identified risks" to the crab population. "There is also a prohibition in place to limit the number of fishers and restrict the method to hand collection only," principal fisheries management officer Graeme Baudains said. Mr Baudains said the department monitored catch numbers and trends. "There is no identified need for a dedicated population survey, given the very low level of take, comparative to the observed population," he said. Mr Cooper's Wildlife Trade Operator proposal is under assessment, with no timeline for a decision.

Australia's hermit crabs are in demand globally but some want the trade banned
A push to export hermit crabs from Western Australia has sparked criticism, with one political party calling to ban the trade over concerns about animal welfare and environmental impact. Merv Cooper runs Crazy Crabs in Western Australia — a business operating since 1979, specialising in the sale of Australian land hermit crabs. He sells these to Australian pet stories, and also exports them internationally to locations including Hong Kong and the United States. But his export permit expired late last year and the federal Department of Climate Change, Energy, the Environment and Water (DCCEEW) is now assessing a three-year extension — a move the Animal Justice Party says would be "reckless and short-sighted". SBS News attempted to contact Cooper for comment but he was unavailable. Experts say it's difficult to know whether harvesting the crustaceans is sustainable, due to regulatory gaps in Australia's hermit crab trade. A little-known industry The species — Coenobita variabilis — is endemic to Australia, found only along the north-western coast of Western Australia and in parts of the Northern Territory. In its proposal to the DCCEEW, Crazy Crabs said the business collects on average 30,000 crabs each. In summer, he and a small crew head out for four to six days at a time, collecting crabs at night on foot using torches and buckets. "Really small" crabs are left on the beach. It says collections happen "only a couple of times a year" and these don't "appear to have any detriment on populations". But reliable data on hermit crab harvesting is scarce. During a typical year, Merv Cooper collects 30,000 crabs from Western Australian beaches — which he sends off to pet shops across Australia. Source: Getty / Jamie La Australian states and territories are responsible for domestic trade, including licensing requirements. This makes it difficult to determine the exact number of active hermit crab export operators in Australia, the quantity of crabs they collect, and the potential impact of this activity. According to an ABC report in 2022, WA Fisheries data indicated around 80,000 land hermit crabs were collected by two active operators that year. At the time, they estimated the commercial value of a hermit crab licence to be between $1 million and $5 million. A DCCEEW spokesperson said the federal government "strictly regulates commercial trade in wildlife and wildlife products from Australian native species, such as hermit crabs. Animal Justice Party MPs say the application highlights a lack of scientific rigour in how such trades are assessed — and could open the door to further exploitation. "This proposal is a stark example of the federal government's failure to uphold rigorous scientific and environmental standards," said Victorian upper house MP Georgie Purcell, "Allowing the commercial export of a native species without comprehensive ecological assessments is reckless and short-sighted." WA upper house MP Amanda Dorn said she is concerned that if the trade is allowed to continue with little regulation, "fragile ecosystems" could be "irreversibly" damaged. In its proposal, Crazy Crabs said WA's Department of Primary Industries and Regional Development does not consider Coenobita variabilis to be in need of formal management plans for protection. It said the number of crabs and the locations where they were collected are reported monthly, as required by state licensing laws. "I have been collecting Hermit crabs for over 50 years and have never seen any need for restrictions," the proposal reads." I don't go to all places every year, hence there is always plenty of hermit crabs." Tim Nichols, a manager at WA Fisheries, told the ABC in 2022 the species was abundant and their population was unlikely to be affected by the current level of fishing. 'Relying on self-reporting': Expert raises concerns Kim Feddema, a wildlife trade expert and lecturer at Edith Cowan University, said the trade relies heavily on licence-holders to assess their own environmental impact, with no baseline population data or independent monitoring. "We need to understand how many hermit crabs are actually in those locations and what role they play in the broader ecology," she told SBS News. "Without baseline data, there's no way to judge the sustainability of this kind of trade." While the international export of native species is subject to federal regulation, hermit crabs are not formally listed as protected. Invertebrates often fall through regulatory gaps, Feddema said, because they're harder to monitor and traditionally not perceived as sentient. Kim Feddema, a wildlife trade expert, said more regulation is necessary in the industry to ensure the welfare of hermit crabs and to understand the environmental implications of their removal.

While shells are often sold as decorations, Feddema notes they once housed live animals. "People often perceive [shells] to be empty, but there is a live animal within them before that stage," she said. Across Asia, including Thailand and Japan, this dual trade has already been linked to population declines. While Australia requires permits to collect hermit crabs at a commercial level, enforcement is limited and operators are not independently monitored. "We're relying on self-reporting here," Feddema said. "There's no verification of what's being collected or the long-term impact on local populations." Are hermit crabs suitable pets? Hermit crabs play a vital role in their native ecosystems, Feddema said, acting as "ecosystem engineers". They recycle shells that would otherwise be buried by sand, creating homes for algae, sponges, and other small organisms. They also help with nutrient recycling by scavenging on waste and decaying animals. But despite this ecological importance, hermit crabs are often marketed as low-maintenance pets — sold in pet stores and online — a characterisation Feddema said is misleading. She said in the wild, they can live for over thirty years. In captivity, however, their lifespans are often significantly shortened — sometimes surviving only a few months or years. She compared the industry to the "cut flower trade", where high mortality rates are treated as inevitable. "People sometimes treat pets the same way they treat cut flowers — that they'll have them for a short period of time and then accept a certain level of mortality," she said. In its proposal, Crazy Crabs said its experience in taking, holding and transporting hermit crabs "has reduced the mortality rate during transit to practical zero for the last ten years". Demand for rare and large individuals is also growing, raising concerns about overharvesting ecologically important crabs that produce a high number of offspring. Studies have shown hermit crabs exhibit signs of sentience, including problem solving, memory and a response to pain — which Feddema said challenges assumptions that invertebrates do not require additional welfare standards. "There is a question about how appropriate they are to be held in captivity," she said. "If the owner doesn't have the particular needs and they're not able to recognise the complexity of owning a hermit crab." She said reforms are urgently needed to assess population health and establish long-term data. "It is very possible that this is a trade that is sustainable, but we just can't make that decision without the data behind it."

Hairy claws make hermit crabs braver, Plymouth study finds
Hermit crabs scuttling along the UK's coastline may be bolder than they appear, especially those with more sensitive claws, according to new research from the University of study reveals that tiny hair-like structures called sensilla on the crabs' claws help them assess their surroundings and decide when it is safe to emerge from their shells. Crabs with more of these sensory hairs were found to recover more quickly and act more researchers hope their findings will inspire further studies into how sensory traits influence animal behaviour. Lead author Ari Drummond, a PhD researcher at the university, said: "I was especially intrigued by how hermit crabs use their claws and antennae when re-emerging from their shells. "The patterns I observed led me to wonder if they might be using their claws to assess environmental risk. "In a world where species face increasing threats, understanding how animals sense and respond to danger is vital."The team studied local hermit crabs in the lab, observing their reactions to being startled and later examining their moulted claw tissue under an electron microscope. This allowed them to count the number of sensilla without harming the findings suggested a link between sensory input and personality, a concept they have called "sensory investment syndrome".Prof Mark Briffa, senior author of the study, added: "We've long known that animals can behave differently from one another. "This research suggests that those differences may be rooted in how they sense the world around them."
