We are Biosean

Embark on an amazing adventure.
We are a marine biology fleet specialised in the observation and study of cetaceans in the Canary Islands. We carry out tours searching for these amazing animals to conduct whale watching with a fast-paced masterclass from great biologists.

An ecosystem

of richness

Species such as the Bottlenose Dolphin Turciops truncatus and the Short Finned Pilot Whale Globicephala macrorhynchus are mainly the inhabitants and residents of these waters. These cetaceans are part of a list of approx. 30 species reported in these oceanic waters, including baleen whales, dolphins and beaked wales, representing more than one-third of the planet’s biodiversity. Learn about their behaviour and habitat from a front row seat. You could live this experience guided by great professionals.

of experts


Misael Morales Vargas (MSc)

Director / Marine Biologist / Captain

Misael is interested in animal biology, ecology a behaviour, specially of cetaceans. He focuses on understanding the aspects related to social learning and knowledge transmission between individuals within one group. Misael has acquired international field work experience as a marine biologist, scuba dive Instructor and boat captain, in the Caribbean Sea, Mediterranean Sea and Atlantic Ocean. He completed his master’s thesis at the Institut Universitaire Europeen De La Mer of the Université de Bretagne Occidentale, Brest, France, where he worked analysing data from the French and Spanish tuna fishing fleets operating in the Indian Ocean. He has managed several research projects and directed his own ecotourism company in Los Roques archipelago, Venezuela. Simultaneously he managed for 5 years a volunteer program for the Lemon Shark’s mark and recapture project, working for the Centro de Investigación de Tiburones (CIT). He has acquired knowledge and experience here in the Canaries working with cetaceans. For many years he has been the biologist and guide of whale watching boats in Tenerife south. Entrepreneur by nature, he has now decided to direct this project that represents the continuation of his career and a lifetime of passion, curiosity and contact with the ocean.

María Alejandra Esteves Ponte (MSc)

Marine Biologist / Head Researcher

Maria Alejandra is a Marine Biologist, working for more than 20 years in the research of cetaceans and the management of their strandings. She mainly conducted necropsies with didactic aims to determine the cause of deaths and analysed the cranium of the animals. She has been Coordinator of many research projects related to whale watching, in order to determine distribution patterns and species identification. She answers some of her scientific questions by studying skulls of odontocetes cetaceans where she uses lineal morphometry and geometric shape analysis. She founded and has been a researcher for more than 10 years at the Centro de Investigación de Cetáceos (CIT), in Venezuela. She founded Proyecto Delphinus in Margarita Island, Venezuela, where she conducted research projects and published many scientific papers. At the moment, she is a PhD candidate in marine sciences at the Centro Interdisciplinario de Ciencias Marinas (CICIMAR) La Paz, Baja California Sur, Mexico, with the subject: Determination of the Archaeofauna of Odontocetos and inferences in use in Ensenada de Muertos, Gulf of California, Mexico. Her goal is to continue gathering scientific information to answer questions about these species, as well as to expand the study of important areas and cetaceans’ populations, such as the waters of Tenerife which play a determining ecological role for the ecosystem. With the BIOSEAN project she is certain to achieve all that with a great team of co-professionals.

Harry Marshall (PhD)

Ecologist / Collaborator Researcher

He is a behavioural and evolutionary ecologist and a Lecturer in Zoology at the Centre for Research in Ecology, Evolution and Behaviour at the University of Roehampton in London, UK. Broadly, he is interested in animal social behaviour and how the costs and benefits of this vary between social group members. He is particularly interested in how social individuals’ behaviour is influenced by changes in the environment, how these individual behaviours scale up to affect group and population level patterns, and how this information can inform the conservation and management of social species. He tackles these question by collecting data from wild animal systems including chacma baboons, banded mongooses and now short-finned pilot whales. His recent work has included understanding how social living drives differences in individual foraging niches and how early-life conditions influence individual behaviour, survival and reproduction in later life. He plans to continue this research on the short-finned pilot whales of Tenerife by exploring their social behaviour and demography and asking what this tells us about their evolution and how to implement effective conservation and management strategies.

María Salomé Rangel (PhD)

Biologist / Collaborator Researcher

Maria is a Biologist interested in ocean conservation and marine ecology. In the early years of her career, she worked with tropical human diseases, which helped her to develop expertise working in the laboratory. However, her driven passion is the field work and the direct contact with nature and its life. This was the reason why she decided to drastically change her study focus. She moved to Margarita Island in the Venezuelan Caribbean and started collaborating with NGO’s involved in cetaceans study and conservation. In parallel, she worked for 10 years at the Universidad de Oriente as Lecturer and Researcher. For the last 10 years of her career, she has focused on studying marine life, with emphasis on cetaceans, sharks and some marine invertebrates.
