Among the largest mammal species worldwide, whales are also the ones
that can live the longest. Many studies have been carried out by
researchers and have determined that, while some have a life expectancy between 80 and 90 years, some specimens can live up to 100 and more.

Their longevity depends on many factors. Studies have been very
difficult to carry out, however, with some data and estimates, marine
biologists have been able to determine whale lifespan with a pretty good
degree of accuracy, for each species in particular.

The word plankton was first used in 1887 by German scientist Victor Hensen. With it, he referred to a group of plant and animal organisms, mostly microscopic, present in salty or fresh waters that move driven by currents.

These diverse organisms populate the oceans around the world but tend
to be more abundant in the colder seas, i.e: distant from the equator.

Their role is essential in the marine food chain and they are usually classified into two categories: phytoplankton or plankton from vegetable origin and zooplankton or animal plankton.

The dolphin is a quite fascinating marine species, and has been considered one of the smartest living animals. It is known for its sociable behavior and empathy, which demonstrates not only within its own species, but also with others.

Although intelligence is usually associated exclusively with humans, this animal exhibits behaviors that can be considered intelligent, something that has surprised scientists for the past decades.

Many people have heard about the cognitive abilities of this mammal,
but most of them are unaware of some characteristics and curiosities
regarding this cetacean.

Oceans comprise the largest extensions of water on Earth, besides
being the natural habitat of countless species. This makes them one of the most important environments for the preservation of life on Earth.

However, up to a third of marine biodiversity is being currently
threatened by the effects of overfishing, climate change and
acidification of the seas.

There are countless reasons to reinforce the preservation of life in the oceans. Some of the most relevant are presented below.

On October 19, we had the places to participate in a double act in favor of the conservation of the rich fauna present on our island, the presentation of the new cetacean conservation letter and the return of 20 turtles to the ocean.

Interview with Alberto Alonso, collaborating biologist at the La Tahonilla recovery center.

La fascinación del ser humano por los delfines nos lleva a muchos de nosotros a preguntarnos si es posible nadar con delfines en Tenerife.

Pues bien, la respuesta a esta pregunta es no, actualmente está prohibido nadar o bañarse con delfines en las costas de Tenerife.

En nuestro país tenemos el privilegio de
contar con un gran número de delfines en nuestras costas, esto nos da la
oportunidad de observarlos en su ámbito natural de una forma
responsable, pero por desgracia también contamos con delfines en cautividad. Ubicados en parques y zoológicos de todo el territorio nacional.

Las aves marinas tienen numerosas adaptaciones para vivir en su medio. La pardela cenicienta presenta las glándulas salinas, o glándula de sal; un órgano que permite excretar el exceso de sal del agua del mar y de los crustáceos. Las glándulas salinas se encuentran al lado de las narinas y excretan sal de manera intermitente. En otras palabras, es como si emitieran estornudos salados.

Siguiendo nuestra ruta de navegación, durante la excursión, podemos encontrar la pardela cenicienta en la zona protegida identificada como El Monumento Natural de la Montaña de Guaza, en particular en al Acantilado Marino.

Las aguas de las Islas Canarias presentan una fauna variada y abundante de especies marinas. Gracias a su ubicación en la región subtropical del oeste africano y a su posición oceánica, poseen singulares características oceanográficas, la superficie terrestre favorece la convivencia de estas especies en aguas cálidas y tropicales.
Alrededor de 30 especies de cetáceos han sido identificadas en nuestras costas, lo que define a este archipiélago como uno de los lugares con mayor diversificación de cetáceos en el mundo y el primero en Europa.
