Crepidula fornicata

Crepidula fornicata (Linnaeus, 1758)

The species has a brown shell that reaches about 6 cm long. The septum divides the interior of the shell into two parts: the external one where the foot and head can move and the internal one where the visceral mass is protected. The plasticity of this species is important and shell can be deformed

Codium fragile subsp. fragile (Suringar) Hariot, 1889

The species originates from the Pacific Ocean (Japan) and has been spread to both hemispheres, mainly due to shipping (Carlton and Scanlon 1985). In Europe, it was first found on the Dutch coasts of the North Sea in 1900 (Silva 1955), and since then, it was introduced in the western Mediterranean through Gibraltar in 1940 (Meslin 1964). Today, it has been spread also in the eastern basin of the Mediterranean Sea, including the Turkish coasts (Gurner et al., 1985)

Chama pacifica Broderip, 1834

Shell large, solid strongly inequivalve with lower valve bigger and deeper than the upper. Outline irregular, generally suboval to subcircular.  Exterior white, red, orange or purple; interior white usually splashed with pale or deep rose, particularly round the margins. Sculpture of short spines more pronounced towards the margin where they are concentrically lamellate. More prominent spines on the left side of the valve. Internal margin encircled by a finely-crenulate-striate ridge. It grows its shell up to 70mm in height.

Erugosquilla massavensis

Erugosquilla massavensis (Kossmann, 1880)

As their common name suggests, it resembles a cross between a preying mantis and a shrimp. The species is easily distinguished from Squilla mantis due to the lack of the paired dark spots on the dorsal part of the telson. Colour light grey-orange dotted with very small dark spots.

Ficopomatus enigmaticus (Fauvel, 1923)

The species resembles a tube-shaped organism. It represents a tube building polychaete worm that presumably origin from the Southern Hemisphere. The species habitat is characterized as the hard needed for the species attachment. Increased abundance of the species can lead to reef like structures up to 4 meters in width and more than 2 meters in height.

Halophila stipulacea

Halophila stipulacea (Forsskål) Ascherson, 1867

A tropical subtidal seagrass that is widely distributed along the coasts of the western Indian Ocean and Red Sea, and forms mono- or poly-specific meadows along the shore line. This species invaded the Mediterranean probably from the Red Sea through the Suez Canal, and it has been known to occur in the Mediterranean basin since 1895.
