The observatory is an independent entity that divulges the best efforts undertaken across the globe in order to preserve marine ecosystems and biodiversity.

Angel shark project | Sponsored by Oceanário de Lisboa

Once widespread in the northeastern Atlantic Ocean, the angel shark (Squatina squatina) is currently extinct across most of its range. Although it can still be found in the Canary Islands, this species is constantly under threat. It is currently listed as “Critically Endangered” on the IUCN Red List of Threatened Species.

Projeto Tubarão-anjo

Net-works - Observatório Oceanário de Lisboa

The goal of this social and marine ecosystem conservation project is to collect abandoned fishing nets near coastal communities. Nets are subsequently recycled and turned into useful items.

Seahorse project | Sponsored by Oceanário de Lisboa

Seahorses are threatened throughout their range as a result of overfishing and habitat loss. The efforts undertaken in order to protect this species also benefit other marine animals and ecosystems, particularly when protected marine areas are created and improvements are made to existing management systems.

Biomares project | Sponsored by Oceanário de Lisboa

This project was designed for the purpose of helping conserve the Professor Luiz Saldanha Marine Park, including the Arrábida Natural Park, and protect the respective biodiversity.

iSeahorse - Observatório Oceanário de Lisboa

Nine seahorse species are currently listed as “Threatened” on the IUCN Red List of Threatened Species. Many more are considered data-deficient, as available information on the respective populations is not sufficient to allow their classification. You can help conserve these species by adding your observations to this online platform/mobile application, which provides information on seahorses, as well as a species identification guide.

Ocean project | Sponsored by Oceanário de Lisboa

In the next decade, our oceans could hold one kilogram of plastic for every three kilograms of fish. This project aims to alert people to the need to reduce plastic waste and draw their attention to the negative impact of this type of waste on marine ecosystems.

Secore International - Observatório Oceanário de Lisboa

Is a leading conservation organization for the protection and restoration of coral reefs.


The conservation of diadromous fish populations depends upon the implementation of management actions that are spatial and temporal representative of the ecological needs of these species. This project by Universidade de Évora, aims to applicate an integrated management plan which is particularly difficult.
