Rathlin MCZ has been designated for deep-sea bed, black guillemot and geological/geomorphological features.

The MCZ contains the only known location of the broad scale habitat, deep-sea bed in Northern Irish waters. This habitat is particularly unique in Northern Ireland inshore waters due to the steep drop-off in depth (>200m), close proximity to land and a range of deep subtidal sands, mixed sediments and rock.

Rathlin Island also supports a large population of black guillemots (Cepphus grylle) that nest within the Island’s cliffs. Although black guillemots have a widespread distribution throughout Northern Ireland there is a significant breeding and nesting population within Rathlin Island. Their reproductive success here may be related to the highly productive waters and rich feeding grounds within the MCZ.

A range of subtidal geological and geomorphological features have also been recorded along the north coast of the Island including a submerged coastline, underwater caves, sea arches and lagoons. These are important indicators of global sea-level change.
