Sea turtles of Macaronesia

Sea turtles of Macaronesia There is something undeniably majestic and special about the slow, leisurely movement of a turtle. This marine animal, capable of traveling thousands of kilometers between continents throughout its life, captivates and floods our curiosity, inspiring legends and mythological symbols in various cultures. More than 150 million years later, sea turtles still inhabit the planet and have managed to survive all kinds of ecological adversities. They are one of the great exponents of Macaronesian culture and biodiversity. Their role in the ecosystem is essential, but their survival is being affected by the degradation of their habitats, gillnetting and accidental fishing, and plastic pollution. However, it is not too late. Sea turtles have an important story to tell, Do you want to know it? [caption id="attachment_14749" align="aligncenter" width="571"]…

The short-finned pilot whale, a treasure in Canarian waters

The short-finned pilot whale, a treasure in Canarian waters By: Marina Tortosa (@aguitasubmarina) The short-finned pilot whale, scientifically known as Globichepala macrorhynchus, is the most common cetacean in the Canary Islands. In the waters around the southwest of Tenerife and the west coast of La Gomera, it is easy to spot a dark silhouette resting in the sea surface near the coast. The more than 400 photo-identified individuals inhabiting the southern waters of Tenerife constitute one of the few resident pilot whale populations in the world. Today we continue to learn about them on each of our tours, and despite being such a common species on the island, they hold many secrets that we still don't know. Want to know more about these incredible cetaceans? Read on! [caption id="attachment_14242" align="aligncenter"…

SOCLIMPACT: the effects of climate change on European islands

Mundo Marino, Sin categoría

SOCLIMPACT: the effects of climate change on European islands By @marinatortosa27 / @aguitasubmarina Global warming is an unequivocal reality. The continued emission of greenhouse gases is causing irreversible changes in the world, and more specifically, in the seas and oceans. The increase of sea temperature, acidification and loss of oxygen are increasingly affecting the marine species that inhabit our waters, modifying their behavior, abundance and distribution. One of the objectives of the SOCLIMPACT project is the study of the vulnerability of cetaceans to these changes, and from BIOSEAN Whale Watching & Marine Science we have contributed our knowledge and experience to help these large marine mammals. Want to know more about this interesting project? Read on! What is the SOCLIMPACT project? The rate of warming of the world's oceans has doubled…

The bottlenose dolphin, protagonist in Tenerife whale watching trips By: Marina Tortosa (@marinatortosa27 / @aguitasubmarina) Anyone who has been lucky enough to enjoy whale watching on the island of Tenerife, undoubtedly knows one of the most commonly observed species in these marine excursions, along with pilot whales: the bottlenose dolphin. These exceptional, friendly and endlessly curious animals, which inhabit warm and temperate seas all over the world, have found in the Canary Islands a natural refuge to live. [embed]http://www.youtube.com/watch?v=3GDOIeyRuv0[/embed] The bottlenose dolphin (Tursiops truncatus) is a species of odontocete cetacean of the family Delphinidae, the largest of all true dolphins (excluding the killer whale and pilot whales): it can reach 4 meters in length and weigh half a ton, although the individuals of the resident populations in the Canary Islands…

Whale Watching Marine Science

Mundo Marino, Sin categoría

[caption id="attachment_1867" align="alignright" width="225"] A participant helping out on data collection.[/caption] BIOSEAN is a project that combines whale watching and marine sciences in Tenerife, through the participation of people (citizen science), students and researchers. Every day we go out to sea with two main objectives: to collect scientific data from our whale watching tours, and to show our clients the wonders of southern Tenerife, with an educational approach, respect for local fauna, conservation, and dissemination of the marine ecosystem. Our research is largely funded through whale watching tours, but we also receive research funds through agreements signed with universities and research centers. These studies allow us to understand marine fauna, and especially cetaceans, thus having useful tools to propose management, conservation and dissemination measures for the marine environment. Our whale…
