Underwater in St Kilda
  • The sea hare (Aplysia punctata) got its name from its rounded shape and two long rhinopheres that project upwards and resemble the ears of a hare.

  • The lobster has long claws covered in hairs with striking red nippers. It is difficult to approach and can move extremely fast when disturbed.

  • There are more than 3,000 known species of nudibranch and new ones are discovered nearly ever day.

  • Sgarbhstac has been labelled a 'must do' for divers visiting St Kilda. You can see light streaming through the arch of the rock outcrop and its roof and walls are full of life.

  • Who would have thought this is what we enjoy served up on a plate with chips?

  • The threadlike body of the skeleton shrimp allows it to virtually disappear among seaweed.

  • Common sunstars can be found from the Arctic right down to the English channel and Pacific Coasts. Very small sunstars are sometimes found in rock pools.

  • The black brittle star can be found in waters as deep as 400 metres and often appears in large numbers with more than a hundred grouped together in a square metre.

  • The lesser octopus is also called the curled octopus because it curls up its tentacles when it rests.

  • They are usually found in rocky areas around the UK in shallow water and often among mussels.
