Bottlenose Dolphins, the kings of the Vigo estuary

You probably didn’t know that our captain Carlos is passionate about bottlenose dolphins. It has a multitude of curious facts about these fellow travelers on the Vigo estuary.


We have always seen them in our waters, accompanying our boats with their jumps and pirouettes while we are heading to the Cies Islands, but it is true that in recent years there has been an increase in population. According to data from the Gremmar dolphin research and rescue group, the resident population is currently stable and is maintained throughout the year with 600 specimens within the estuaries.

From the study center ‘Bottlenose Dolphin Research Institute’ (BDRI), its director Bruno Díaz López, points out a community of 250 copies in the Rías Baixas. The estuaries of Vigo, Pontevedra, Arousa, the Cies, Ons and Sálvora islands, and even Muros, are some areas through which they move throughout the year.

Now we go with the curiosities:

  • Their social behavior is what makes them approach ships. That is, they are not shy. If we had to choose a marine companion as a pet, surely bottlenose dolphin would be the best option.
  • In Galician they are also called arroás, boot, boto, botiña, botiño, bufa, bufo, bufana.
  • They differ from other species by their su bottleneck nose and their ‘ smile ’.
  • As for reproduction, males reach sexual maturity at age 11. This is a problem on some occasions, since some specimens have too much testosterone. Do you remember Gaspar? When a solitary dolphin exists, it may have been expelled from the mananda due to its high activity. You already understand us;)
  • Their herds form a family unit, where everyone has their own name. It is fascinating that each dolphin has a specific sound to identify itself. In this, they are more advanced than us. There are never two ‘Peter’ or two ‘ Mary’. Each dolphin is unique.
  • Families are usually 12 and are run by the femias. Males usually live in isolation or in smaller groups, because of the testosterone problem.
  • They live on 30 years, the males and 40 the femias.
  • Dolphins are good culinary lovers and do not waste any sea food. Sardine and other fish are found in their diet. They also help regulate the ecosystem by keeping predatory species at bay.

Do you want to see them jump around our catamarans? You just have to contact. We can’t think of a better plan for this fall!
