Article Synopsis
- The IUCN Red List reports 832 species extinct since 1600, but this is a small percentage of overall biodiversity, particularly since most invertebrates remain data deficient.
- A study on Hawaiian land snails (Amastridae) evaluated 325 species and found that 88 were extinct and 15 were still living, while 179 lacked sufficient evidence but likely are extinct.
- The research indicated a rising extinction rate for amastrid snails over time, estimating an average of about 5% per decade since the mid-1800s, highlighting the vulnerability of oceanic island species to extinction.

Article Synopsis
- Many believe we're facing a massive extinction crisis, but only a tiny fraction (0.04%) of known species have been officially recorded as extinct since the 1980s, leading to skepticism about the crisis' severity.
- The low extinction figure largely arises because most invertebrates, which make up a significant part of biodiversity, haven't been properly evaluated.
- New research suggests that around 7% of species on Earth, equivalent to about 130,000 extinctions, may have already occurred, emphasizing the need to include invertebrates in extinction assessments for a clearer understanding of biodiversity loss.

Article Synopsis
- Mollusks are one of the groups most affected by extinction, and their situation hasn't been fully checked since 2000.
- Research shows that there are actually almost twice as many known mollusk extinctions than what is listed by the IUCN Red List.
- Most of these extinctions happened on oceanic islands and in freshwater areas, especially in the U.S., and one major cause was a predatory snail called Euglandina rosea.
