Central Lyme Bay has a silty seabed, the predominant
rock being blue lias limestone with beds of clay that produce
a cloudy silt. Parts of the seabed are composed of thick mud,
other areas consist of fine gravel swept in broad ripples
by wave action. In other areas the seabed is flat bed rock
scattered with boulders or raised into reefs. Depths lie between
20 and 30 metres. In recent years interest has focussed on
the ecology of the pink sea fan Eunicella Verrucosa, a gorgonian
(soft coral) that grows in profusion on some of the reefs.
The fans align themselve broadside on to the current and can
be seen in strong tides to be shaking gently. They have a
natural predator, a tiny sea slug or nudibranch. known as
Tritonia that is perfectly camouflaged whilst feeding on the
fan's polyps.
Another interesting species found relatively
recently is the Sunset cup coral which exists in profusion
on some underwater cliffs at depths of 25 to 30 metres. The
coral is brightly coloured enough to stand out even at depths
where most colours have been filtered out.
Some species in the bay are at the limits of
their distribution or exist abundantly in a relatively small
number of areas such as the Trumpet Anemone (Aiptasia) or
the Blackfaced Blenny. Both these species are found in the
Mediterranean.

Wrecks
There are countless wrecks off the British coast. South
Devon wrecks are extremely popular with divers. The
James Egan Lane was a Liberty ship sunk during the Second
World War. It lies a few miles west of Plymouth off
Whitsand Bay in about 20 metres of water. On a fine
summer's weekend numberous dive boats can be seen around
it and the nearby Scylla a naval vessel deliberately
sunk as an artificial reef in 2004.
