- Levantine Sea is the name of the Eastern most part of the Mediterranean Sea and can be characterized by its high temperatures (16 degrees Celsius in winter and 27 degrees Celsius in summer) and salinity levels (39.1psu in Cyprus and more than 37.5psu in the Eastern Mediterranean).
- The largest depth of the Levantine Sea is 4384 meters and is found in the Pliny Trench, which is located around 80km South of Crete.
- The Levantine Sea covers an area of 320,000km with Cyprus being its largest island.
- Cilician Sea is the name given to the Northern part of the Levantine Sea and is located between Cyprus and Turkey.
- The Levantine Sea is one of the most oligotrophic seas on Earth since availability of nutrients is very low.
- In Cyprus there are no permanent river flows and coastal upwelling which are the main two factors affecting nutrient availability. Due to this fact, nutrients remain unutilized at the bathypelagic zone (1000-4000 meters depth) allowing very little amounts in the euphotic zone (0-200 meters depth), which lead to less primary production and in turn affecting the whole marine food chain.
- Some species found in Cyprus such as Chelonia mydas (green sea turtle) and Caretta caretta (loggerhead seaturtle), the Pinna nobilis (noble pen shell) and Monachus monachus (Mediterranean monk seal) are measured as threatened and in necessity of protection since they play a major role in the marine food chain in the entire Mediterranean Sea.
- Sensitive and important marine habitats in Cyprus include Posidonia oceanica and Cymodosea nodosa, also known as the meadows of marine angiosperms, and are considered as sea grass species that are endemic to the Mediterranean playing an ecologically important role.
- Moreover, species including Cystoseira are a genus of brown algae and produce forests of kelp in the marine environment of Cyprus. They are generally widely distributed and provide an essential habitat for many epiphytes, invertebrates and fish commonly found in temperate regions.
