Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Desmarestia tropica faces severe threats from ocean warming and acidification, which directly impact its physiological processes and reproductive success. Coastal development and pollution in tropical marine environments have degraded the pristine waters this brown algae requires. The species' limited distribution makes it particularly vulnerable to localized environmental changes and extreme weather events.

Threat summary

Habitat

Desmarestia tropica inhabits shallow tropical marine waters, typically growing attached to rocky substrates in clear, nutrient-rich coastal environments. This brown algae species requires specific temperature ranges and water chemistry conditions found in pristine tropical reef systems.

Why is Desmarestia tropica classified as Critically Endangered?
Desmarestia tropica is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Desmarestia tropica faces severe threats from ocean warming and acidification, which directly impact its physiological processes and reproductive success. Coastal development and pollution in tropical marine environments have degraded the pristine waters this brown algae requires. The species' limited distribution makes it particularly vulnerable to localized environmental changes and extreme weather events.
Where does Desmarestia tropica live?
Desmarestia tropica occurs in Peru. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
