Sea Hare – Aplysia puncata, is a species of sea slug, which might look like it is missing its shell, but it is there, underneath the beautiful soft body parts. It can grow up to 30 cm, but up in the north the maximum has been around 7 cm. Normally it is read-brownish in colour, but you can also see lighter versions turning towards purple, green or even black, all depending on what it has eaten. If the sea hare feels threaten it can let out a purple coloured secret as a defence.
The Sea Hare is unusual to see here in Saltstraumen. Two years back there were a big colony showing off up here, the first time in over a decennium, and last year it was seen at Tuvsjyen, Sundstraumen and Mørkvedbukta but in smaller numbers. We have seen them legging eggs, maybe they are here to stay?
In science, especially in research regarding pain, the Sea Hare is a popular thanks to its rather simple nerves system with big nerve cells.
