European Common Cuttlefish are spotted across virtually all sites and are the region's signature species.

Gray Seal turns up occasionally, and Conger Eel, Pollack, and Cod have all been observed at various sites.
Several sites are well suited to those early in their diving career. Brighton Pier is a shallow, shore-entry artificial reef and wreck site rated beginner level, and Newhaven West Arm offers similar accessible conditions with both shore and boat entry options. More advanced divers can progress to deeper offshore wrecks such as Clodmoor, which requires greater experience.
A good number of sites are reachable directly from the shore, including Brighton Pier and Wide Water Beach, making independent or guided shore diving straightforward. Deeper offshore wrecks like Clodmoor require a boat, and operators including Newhaven Scuba, Channel Diving, and Planet Divers run regular trips. Newhaven West Arm can be accessed both ways, offering flexibility.
The region mixes natural reef, artificial reef, and wreck diving across a compact stretch of the Sussex Coast. Artificial reefs such as those at Brighton Pier and Newhaven West Arm support dense invertebrate life, while offshore wrecks provide structure and shelter for fish including Pollack and Cod. This variety means divers of different interests and experience levels can find rewarding options within the same area.
