Thanks to the Municipality of Nardò, the Marina di Porto Cesareo Biological Station was inaugurated in 1966 after donating some collections of sea biology. There are 690 tropical animals and fish from the abyss. This area was set up for scientific research and education. There are some underwater pathways; the so-called blue pathways allow the monitoring and study of protected fauna and flora of the sea. Visitors can also snorkel or observe the bottom of the sea from boats with a transparent floor.
