Large numbers of sea hares in Guernsey waters ‘not unusual’

A Guernsey based scientist has encouraged islanders to report sightings of sea hares, after hundreds were spotted in island waters.

The sea hares, often called sea slugs, were seen in large numbers by local residents around the QEII Marina, prompting questions on social media about a potential population boom.

The sea hares are predominantly spotted sea hares, or Aplysia Punctata, and can grow up to 20cm (8ins) in length.

Liz Sweet, also known as the Guernsey Scientist, said the large numbers present in shallow waters around the island was “not that unusual.”
