              - Sepiola atlantica

Little Cuttlefish

Sepiola atlantica

Observation: Captured off Lancing Beach by Andy Horton.

Also known as the Atlantic Bobtail Squid. Unlike the larger Common Cuttlefish, these small cephalopods often bury themselves in the sand during the day, coming out at night to hunt for small crustaceans.
Large Black Slug
              - Arion ater

Large Black Slug

Arion ater

Site: West Sussex gardens and damp woodlands.

A highly adaptable terrestrial gastropod. While known as the "Black Slug," they are famous for their variation in colour, appearing in shades from deep orange to jet black.
Kentish Snail -
              Monacha cantiana

Kentish Snail

Monacha cantiana

Site: Recorded in Lancing; common on roadside verges and chalk scrub.

A medium-sized snail with a pale, creamy-white shell. A key identification feature is the reddish or brownish tint often found just behind the "lip" of the shell opening. Despite its name, it is found throughout Southern England.
This species is often found climbing tall grasses and umbellifers during damp weather to avoid the heat of the ground.
Water Snail -
              Lymnaea sp.

Pond Snail

Lymnaea sp.

Habitat: Freshwater ponds and slow-moving ditches.

A common inhabitant of garden ponds and local waterways. Unlike land snails, these freshwater molluscs often have more pointed, elongated shells. They are vital for pond health, acting as "cleaners" by consuming algae and decaying plant matter.
Observation: Note the lack of long stalks for eyes; water snails typically have their eyes at the base of their tentacles.

Recorded: 28 March 2026 | Garden Sighting
