Defined as an extended period of high-water temperatures, heat waves are expected to increase before the end of the century.

Focused on the coast of Sao Paulo, Brazil, a 35% increase in marine heatwaves is projected by 2100, according to a study published in the Journal of Estuarine, Coastal, and Shelf Science.

Particular species at the bottom of the food chain are vulnerable to the impacts of marine heatwaves.

In order to assess the effects of marine heatwaves, the Atlantic mangrove fiddler crab, known as Leptuca thayeri, was studied.

A significant rise in the mortality of the crab larvae was led by an increase of 4 degrees Celsius.

A threat to the species and its surrounding ecosystems is posed by the decline in survival rates of the Atlantic mangrove fiddler crab.

Fiddler crabs lay their eggs in mangrove forests and then make their journey to the ocean after hatching.

The survival rate of crab larvae is only about 1% as they return to the mangrove due to being a food source for various land species.
