BAY OF ISLANDS, Aotearoa New Zealand — Since an invasive seaweed called caulerpa was discovered in Aotearoa New Zealand in 2021, forming meadows that blanketed parts of the seabed, it’s taken on an almost mythical status among people who spend time in coastal waters. “It’s so wily and so resilient,” Michele Rogalin-Henderson, a doctoral candidate at the University of Auckland’s Institute of Marine Science, told Mongabay. “Yes, I did say wily,” she added. “I anthropomorphize it. I spend a lot of time in the lab and in the field with this beast.” Stephen Te Tai, a commercial diver who removes the caulerpa, mainly in the Bay of Islands area in New Zealand’s tropical far north, also spoke about the invasive seaweed in such terms. “I know it’s airy fairy but sometimes I feel its energy,” Te Tai told Mongabay. In winter, he said, “it’s real low, it’s almost cowering, but in the summertime, it feels like its chest is puffed out, and it’s real vibrant and strong.” Te Tai is Ngāti Hine, a Māori tribal grouping, and his surname means “coast” or “tide” in Māori. He spoke to Mongabay on the shoreline after he’d worked in the waters off Urupukapuka Island one day in July. “The moana [ocean] is vital to our people,” he later added in a text message. “It is not just something that nourishes us, it is a part of us, it was a part of our ancestors and it will be part of our mokopuna [descendants].…This article was originally published on Mongabay

PORTO ALEGRE, Brazil — “Good choice!” said the clerk at one of the fish stalls in the Porto Alegre Public Market when Mongabay asked about the peixe anjo, which means “angel fish” in Portuguese, in mid-September. “We sell a lot of these. It’s really good, and it doesn’t have any bones.” The same product was for sale by at least four other fishmongers in the traditional market of the capital of Rio Grande do Sul state, in the South of Brazil. Prices were attractive, ranging from 30 to 37 reais per kilo ($5.70 to $7). The problem is that the “angel” isn’t just any fish — it’s a shark. More specifically, an angelshark, and in Brazil, that means three of the world’s most endangered shark species: Squatina guggenheim, the angular angelshark; S. occulta, the hidden angelshark; and S. argentina, the Argentine angelshark. And fishing of these species is prohibited in Brazil. For many years, the Brazilian government authorized the import of angelsharks from neighboring countries. According to data from the Federal Revenue Service obtained by Mongabay through the Freedom of Information Act, 48 metric tons of S. guggenheim meat and 194.6 metric tons of S. argentina entered Brazil between January 2021 and Sept. 10, 2026, totaling 242.6 metric tons. Most of the shipments came from Argentina, entering the country through the customs ports of São Borja and Uruguaiana municipalities in Rio Grande do Sul, and Dionísio Cerqueira in Santa Catarina state. Once in Brazil, the imported product was mixed with…This article was originally published on Mongabay

A push to reopen the door to commercial whaling failed at the recent meeting of the International Whaling Commission (IWC) after a controversial resolution was taken off the table on the last day. The draft resolution, put forward by the Caribbean nation of Antigua and Barbuda and co-sponsored by Palau, St. Kitts and Nevis, St. Lucia and Togo, called for the IWC to discuss the “sustainable use of whale resources” and introduced a path toward the reintroduction of commercial whaling. The bill, however, was ultimately withdrawn by another Caribbean nation, Grenada, which did not co-sponsor the bill, leaving the IWC’s 40-year-old global moratorium on commercial whaling intact. The IWC, an intergovernmental organization that oversees the management and conservation of cetaceans, including whales, dolphins and porpoises, convened its 70th meeting between Sept. 27 and Oct. 2 in Hobart, Tasmania. Approximately 400 delegates from all 89 member governments and several observer organizations attended this year’s commission meeting, which has been held biennially since 2012. The meeting marked 80 years since the IWC was established and 40 years since the moratorium it placed on commercial whaling took effect. The International Convention for the Regulation of Whaling, the international agreement that established the IWC in 1946, only refers to baleen and toothed whales, leading some to believe the moratorium only applies to these species, and not smaller cetacean species. Experts say the moratorium has aided the recovery of many whale species once on the brink of extinction due to whaling. But other threats to…This article was originally published on Mongabay
