Week in wildlife: a flying teddy, a fishy shipwreck and a globe-trotting sea slug | Environment

In sea slug news: a “groundbreaking” discovery has been made, with the nudibranch Spurilla neapolitana, typically found in much warmer climates, turning up in Cornwall. The colourful sea slug usually lives the Caribbean, the Mediterranean, and along the western Atlantic. Until now, its most northerly sighting was in Brest, France
