Dungeness Crab Impacted by Acidification

“This is the first study that demonstrates that larval crabs are already affected by ocean acidification in the natural environment, and builds on previous understanding of ocean acidification impacts on pteropods,” said lead author Nina Bednarsek, senior scientist with the Southern California Coastal Water Research Project. “If the crabs are affected already, we really need to make sure we start to pay much more attention to various components of the food chain before it is too late.”

New report connects ocean changes with human activities on land.

The report makes clear that to protect the ocean, we must first reduce our dependence on fossil fuels. But we must also reduce ocean stress, caused by overfishing and pollution, so the ocean is healthy enough to weather the changes already underway.

“The bottom line is that we need the ocean. And right now, the ocean needs us,” said Julie Packard, executive director of the Aquarium. “It’s not too late to take courageous climate action and safeguard the ocean from further damage.” 

Low Oxygen Levels Impact Marine Invertebrates

With rising global temperatures already lowering marine oxygen levels – to the point of producing and exacerbating coastal ‘dead zones’ – this could become a serious problem.

Many marine invertebrates – just like other animals with functional and complex eyes – depend on vision for survival. It helps them find prey, avoid predators, and locate shelter.
