A rare New Zealand snail has been filmed for the first time squeezing an egg from its neck, delighting scientists trying to save the critically endangered meat-eating mollusk.

Threatened by coal mining in New Zealand's South Island, a small population of the Mount Augustus snail was transplanted from its forest habitat almost 20 years ago to live in chilled containers tended by humans.

Little is known about the reproduction of the shellbound critters, which can grow so large that New Zealand's conservation department calls them "giants of the snail world".

A conservation ranger said she was gobsmacked to witness a captive snail laying an egg from its neck -- a reproductive act well documented in other land snails but never filmed for this species.

"It's remarkable that in all the time we've spent caring for the snails, this is the first time we've seen one lay an egg," conservation ranger Lisa Flanagan said this week.

"We caught the action when we were weighing the snail. We turned it over to be weighed and saw the egg just starting to emerge from the snail."

Conservation department scientist Kath Walker said hard shells made it difficult to mate -- so some snails instead evolved a special "genital pore" under their head.

The Mount Augustus snail "only needs to peek out of its shell to do the business," she said.

The long-lived snails can grow to the size of a golf ball and their eggs can take more than a year to hatch.

They eat earthworms, according to New Zealand's conservation department, which they slurp up "like we eat spaghetti".

Conservation efforts suffered a drastic setback in 2011, when a faulty temperature gauge froze 800 Mount Augustus snails to death inside their climate-controlled containers.

Fewer than 2,000 snails currently live in captivity, while small populations have been re-established in the New Zealand wild.



Many US Ice Cream Producers to Phase Out Artificial Food Dyes by 2028

Dozens of US ice cream producers are planning to remove artificial colors from their products by 2028, a dairy industry group and government officials said on Monday.

The producers, which together represent more than 90% of ice cream sold in the US, are the latest food companies to take voluntary steps to remove dyes since Health Secretary Robert F. Kennedy Jr. in April said the US aimed to phase out many synthetic dyes from the country's food supply.

Several major food manufacturers, including General Mills, Kraft Heinz, J.M. Smucker, Hershey and Nestle USA, have previously announced their plans to phase out synthetic food coloring.

The 40 ice cream companies will remove Red 3, Red 40, Green 3, Blue 1, Blue 2, Yellow 5, and Yellow 6 from their retail products, excluding non-dairy products, according to the International Dairy Foods Association.

The IDFA announced the plan at an event at the US Department of Agriculture headquarters on Monday with Kennedy, FDA Commissioner Marty Makary and Agriculture Secretary Brooke Rollins.

"We know that our current health outcomes, especially for our children, are unsustainable and that American agriculture is at the heart of the solution to make America healthy again," Rollins said at the event, referencing a slogan aligned with Kennedy.

Rollins and Kennedy have worked closely together on food sector efforts like encouraging states to ban soda from the nation's largest food aid program.

Kennedy has blamed food dyes for rising rates of ADHD and cancer, an area many scientists say requires more research.

The IDFA said artificial dyes are safe, but that ice cream makers are taking the step in part to avoid disruption to sales from state efforts to phase out dyes from school foods and West Virginia's recent food dye ban.
