Marine Action Research

About MAR

Marine Action Research (MAR) provides an opportunity for aspiring scientists and passionate conservationists to learn practical fieldwork skills, gain scientific scuba diving experience, and explore qualitative and quantitative data at the Zavora Marine Lab in southern Mozambique. MAR focuses on manta rays, sharks, humpback whales, nudibranchs, seahorses, and reef colonization through investigations of the marine life and coastal ecosystems of Zavora Bay. Zavora has an incredible amount of biodiversity and offers the opportunity to study these unique and charismatic species in one of the most beautiful and wild areas of southern Mozambique.

Manta Rays

Manta research aims to generate knowledge of the region’s manta ray populations and assist with their conservation in southern Mozambique.


Zavora Marine Lab is conducting the first assessment of nudipleura in Mozambique: solving a complex of species problems and describing new species.


Humpback whales come to Zavora each year to reproduce and give birth. Land-based surveys and fluke ID help provide estimates of humpback populations travelling through the region.

Artificial Reefs

Of the 2 wrecks in Zavora, the newly sunken Rio Sainas [2013] provided an excellent opportunity to monitor the colonization of an artificial reef right from ground zero.


Together with iSeahorse, MAR aims to assess and monitor seahorse populations, trends, and threats in the Inhambane region.


Visual surveys and baited remote underwater videos (BRUVs) are helping to collect baseline data on the elasmobranch species in the region.


Five of the seven sea turtle species can be found in Mozambique. In Zavora, we commonly see 4 of these on our reefs, two of which are known to nest on our beaches.

About the Zavora Marine Lab

-24.513552, 35.193464 | Praia de Zavora | Mozambique
Research. Dive. Explore.

The Zavora Marine Lab was founded in 2009 by marine biologist Yara Tibirica to investigate and conserve the unique marine life and coastal ecosystems of Zavora Bay. Zavora is one of the last places in Mozambique where manta rays and other marine megafauna species can be found in high abundance. Marine Action Research offers the unique opportunity to study a marine ecosystem with little human impact and where much of the reef is still yet to be explored. The lab's ongoing research is focused on manta rays, sharks, humpback whales, nudibranchs, seahorses, and artificial reef (wreck) colonization.

  • Research mentorship

    Limited group size allows for quality one-on-one guidance with a trained marine biologist during your internship or university project.

  • Competitive fees

    Internship fee includes accommodation (self catering), all research dives (gear included), airport transfers, field trips, and theoretical and practical training.

  • Scuba diving

    Mozambique has some of the best diving in the world. Expect to see manta rays, sharks, stingrays, whales, dolphins, and an astonishing diversity of macrolife

  • Community environment

    Interns live together, work together and develop lasting friendships
