Whale watching – Biosean


The ecosystem is our dedication

We are an organization conducted by marine biologists and researchers. We professionally teach you the mysteries of the sea by combining whale watching tours and research on the most fascinating marine species

An ecosystem of pure wealth

Tenerife has hosted about a quarter of the planet’s cetacean biodiversity, as well as a wide variety of fish, birds and sea turtles, invertebrates, among others

whale watching


There are about thirty species of dolphins and whales that have been observed in the Canarian waters, which represents more than a third of the biodiversity of the planet’s cetaceans. Two of them are residents in the south of Tenerife. This is the case of the Calderón Tropical (Gobicephala macrorhynchus) and the Bottlenose Dolphin (Tursiops truncatus). It is also common to find baleen whales, sperm whales, spotted dolphins, striped dolphins and common dolphins

fish watching


There is a great diversity of species in the Canary Islands. These vertebrates have colonized almost every marine environment. We find them on the coasts near the rocky and sandy bottoms (fulas, trumpets, green fish, abbots, salemas, old), in the open sea (tuna, bonito, hammerhead shark, blue shark) and in great depths (shark, swordfish, candil). Most are bony fish, but there are also cartilaginous fish (sharks and rays)

aves watching


Tenerife is the habitat of many species of seabirds. The Cory’s Shearwater (Calonectris borealis) is the most emblematic. We can also find other birds like the European Storm Petrel (Hydrobates pelagicus) and the Common Tern (Sterna hirundo) at different times of the year. It is still possible to see the endangered fishing eagle (Pandion haliaetus), whose population has been decimated by anthropogenic causes

tortle watching

Sea turtles

Five species reported for Tenerife. It is normal to encounter the turtle Boba (Caretta caretta) and near the coast with the green turtle (Chelonia mydas). Less frequently, Hawksbill (Eretmochelys imbricata) and Laud (Dermochelys coriacea) are observed. In 2018 an olive turtle individual was reported

We protect our passion

In each tour we try to clean the ocean from plastics and other solid waste. We protect the ocean we love deeply and wish to contribute to its conservation

Scientific studies speak for themselves

Scientific studies reveal that about 80% of the mackerel (Scomber scombrus) fished in Canarian waters has microplastics in their digestive systems. These small fish are found in the first levels of the food chain and the ingested bio plastic accumulates in the rest of the chain. Seabirds are also affected by plastic. It is estimated that up to 90% of the aquifers that nest in the Canary Islands have stomach plastics. We found sea turtles entangled in plastics and cetaceans stuck on the coast with plastic materials in the stomach. We cannot go unnoticed. The waste we collect represents deadly traps for our local fauna
