The beach on the Romanian Black Sea shore was invaded between the cities of Agigea and Eforie by “Black Widow” spiders, a species considered as extremely dangerous. Marine Biology Institute chief, Gheorghe Mustata, says the first signals came from a teacher who was conducting a summer practice session with his students.

“Some 200 such spiders were seen around the Agigea beach, on the way to the Eforie resorts. The population must be alerted and informed, so that people wouldn’t come into contact with such creatures”, said Gheorghe Mustata.

According to the official, the phenomenon was possible due to the warm winter and extremely hot summer.
