What this video covers

Wreck diving at Dvergsøya, near Kristiansand, Norway, reveals a submerged car and a boat wreck in the same bay once used as a Norwegian royal summer cabin.0:43 Ann-Elin Synnes dives the site from shore, swimming around a headland to locate both wrecks.0:59 The boat wreck sits deeper than expected, and low light from overcast skies and depth combine to produce dark footage.4:39 The dive also surfaces several marine biology observations: starfish larvae of the species *Luidia sarsi* carry a transparent tail that detaches when the juvenile starfish settles, yet the tail continues living independently for months afterward.2:31 Japanese wireweed, an invasive algae now widespread across Europe, appears on the site, its leaves coated with bryozoans.3:23 Dead man's fingers (*Alcyonium digitatum*), a soft coral common in Norwegian waters, colonize the wreck structure, with some polyps extended and others retracted; the oldest recorded individual reached 28 years.4:56 A large starfish, possibly a sun starfish, also appears near the wreck.7:56
