Mysterious case of sharks that lived in a golf pond for 17 years – then disappeared
A group of bull sharks found living in an artificial golf pond sparked concern when they mysteriously vanished. Bull sharks (Carcharhinus leucas) are often found in rivers all around the world, but this incident makes "the longest uninterrupted duration in a low salinity environment that ever has been recorded in this species". Now, a new paper has investigated the case to understand the tolerance of bull sharks in low-salinity habitats. In 1996, six sharks were discovered in a golf course near Brisbane. They were landlocked for a further 17 years, before vanishing in 2013. The sharks became trapped due to major flooding of two adjacent Logan and Albert rivers. When the floods calmed, the sharks remained in the lake. The young sharks reportedly grew to 9.8 feet (3 meters) long as years went by and reportedly survived on flathead grey mullet (Mugil cephalus), Indo-Pacific tarpon (Megalops cyprinoides), mangrove red snapper (Lutjanus argentimaculatus) and yellowfin bream (Acanthopagrus australis). "If sharks can get the food they need, being in these low-salinity environments can be super beneficial because there are fewer predators," Michael Heithaus, a shark biologist at Florida International University told Live Science. "Pups in some nurseries may go years in virtually fresh water, so it isn't too surprising they survived, as long as there was plenty of food." Some of the sharks were last spotted in 2015, while others were able to escape into the riverways during a flood in 2013. Study authors predicted some of the sharks had sadly died after one carcass was retrieved by golf course staff. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Trump news – live: Kevin McCarthy unsure Trump ‘strongest’ Republican candidate against Joe Biden in 2024
Despite his large lead in a crowded Republican primary field, House Speaker Kevin McCarthy says he does not know if Donald Trump is the “strongest” candidate to take on President Joe Biden in the 2024 election. In an interview on CNBC, Mr McCarthy said Mr Trump can beat Mr Biden but that he’s not sure another Republican couldn’t do better. Later in the day, the speaker appeared to walk back the remarks by telling Breitbart that the former president is “stronger today than he was in 2016”. On Monday night, bombshell audio revealed the former president apparently bragging about possessing still-classified military documents about Iran after he left the White House. In the recording, from a July 2021 meeting at Mr Trump’s Bedminster golf club and released by CNN, the former president is heard audibly shuffling the documents. Mr Trump took to Truth Social to fume about the tape, railing against “Deranged Special Prosecutor” Jack Smith and baselessly accusing the DOJ and FBI of leaking it. Meanwhile, Mr Trump’s co-defendant in the classified documents case, his aide Walt Nauta, has had his arraignment in Miami postponed after his flight was delayed by bad weather in New Jersey. Read More Trump fumes about ‘illegally leaked’ CNN tape of him boasting about classified documents Donald Trump countersues E Jean Carroll for defamation over rape claims Rudy Giuliani interviewed by special counsel over 2020 election interference attempts, says report Trump wants to keep 'communists' and ‘Marxists’ out of the US.
