US EditionSharks are famous for fearsome teeth, but ocean acidification could make them weaker
German researchers found shark teeth exposed to projected 2300 ocean acidity suffered cracks, holes, and corrosion, threatening these predators' survival tools, study shows.
- Sharks rely on their teeth to catch prey, which is vital for the ocean's top predators.
- More acidic oceans lead to more brittle and weaker shark teeth, according to a study that examined sharks' teeth under different ocean acidification scenarios.
- While their teeth may become more efficient at cutting, ocean acidification could make sharks' teeth structurally weaker and prone to breaking, potentially endangering their ecological success.

Acidification could make shark teeth weaker
PORTLAND, Maine — Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.

Independent EspañolBy PATRICK WHITLE PORTLAND, Maine, USA (AP) — Sharks are the most feared predators of the sea, and their survival depends on an imposing denture that regenerates throughout their lives. However, changes in ocean chemistry could put those weapons at risk. That is the conclusion of a study conducted by a group of German scientists who tested the effects of a more acidic ocean on shark teeth. Scientists have linked human activity, including burning…
