Guernsey Sea hares and sea slugs

Subclass Opisthobranchia (including order aplysiomorpha (mainly sea hares)); sacoglossa; pleurobranchomorpha; and nudibranchia (colourful sea slugs with gills exposed on the dorsal surface.)

More nudibranch images can be seen in the Fish Quay, St. Peter Port harbour gallery at http://sealord.smugmug.com/gallery/3514928#200787061

These two sea slugs, Discodoris planata, were found under a boulder lying on gravel in a low lying area of a promontory or ridge of rock that extends into Belle Greve Bay that is mostly covered by the sea at high tide. As the tide rises, the sea streams over this low lying gravel area where the sea slugs were found. This species has acid glands in its skin presumably to deter predation. It can be identified apart from the similar sea lemon, Archidoris pseudoargus, because Discodoris planata has brown spots under the skirt of the mantle. Photographed on the 19 February 2007.<br />

Sealord photography's biodiversity images began with a focus on international commercial seafood species and the marine life of the Bailiwick of Guernsey, Great Britain.

Sealord photography has a growing collection of digital images covering climate change, the environment and sustainability issues.

Sealord photography also covers the Guernsey community and particularly the fund raising activities of Guernsey charities as part of the island's social sustainability.

The fish, shellfish and marine life images would not be possible if it were not for the generosity of commercial and recreational fishermen in Guernsey, and seafood suppliers at various trade shows in the USA, and wholesalers at Fulton Fish Market in New York City.

Many marine biologists have helped identify or confirm the identity of marine species photographed. These people have been mentioned when possible.
