The Collective Article ‘New Mediterranean Biodiversity Records’ of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article is divided in two parts, for records of alien and native species respectively. The new records of alien species include: the red alga Asparagopsis taxiformis (Crete and Lakonicos Gulf) (Greece); the red alga Grateloupia turuturu (along the Israeli Mediterranean shore); the mantis shrimp Clorida albolitura (Gulf of Antalya, Turkey); the mud crab Dyspanopeus sayi (Mar Piccolo of Taranto, Ionian Sea); the blue crab Callinectes sapidus (Chios Island, Greece); the isopod Paracerceis sculpta (northern Aegean Sea, Greece); the sea urchin Diadema setosum (Gökova Bay, Turkey); the molluscs Smaragdia souverbiana, Murex forskoehlii, Fusinus verrucosus, Circenita callipyga, and Aplysia dactylomela (Syria); the cephalaspidean mollusc Haminoea cyanomarginata (Baia di Puolo, Massa Lubrense, Campania, southern Italy); the topmouth gudgeon Pseudorasbora parva (Civitavecchia, Tyrrhenian Sea); the fangtooth moray Enchelycore anatine (Plemmirio marine reserve, Sicily); the silver-cheeked toadfish Lagocephalus sceleratus (Saros Bay, Turkey; and Ibiza channel, Spain); the Indo-Pacific ascidian Herdmania momusin Kastelorizo Island (Greece); and the foraminiferal Clavulina multicam erata (Saronikos Gulf, Greece). The record of L. sceleratus in Spain consists the deepest (350-400m depth) record of the species in the Mediterranean Sea. The new records of native species include: first record of the ctenophore Cestum veneris in Turkish marine waters; the presence of Holothuria tubulosa and Holothuria polii in the Bay of Igoumenitsa (Greece); the first recorded sighting of the bull ray Pteromylaeus bovinus in Maltese waters; and a new record of the fish Lobotes surinamensis from Maliakos Gulf.

Özet:Benekli pisinin kör bölge otolitinde merkez tam ortada bulunurken, gözlü bölge otolitinde ise otolitin posterior kısmına daha yakındır. Bundan dolayı, opak ve hiyalin halkalar kör bölge otolitinde hem anterior hem posterior kısımda gözlenebilirken, gözlü bölge otolitinde merkez posterior tarafa daha yakın olduğu için halkalar bu kısımda çakışmakta ve halka devamlılığının takibi güçleşmektedir. Kör ve gözlü bölge ortalama otolit boyları 4.599 ±0.069 mm ve 4.768 ±0.067 mm (P<0.05), genişlikleri 3.285 ±0.043 mm ve 3.511±0.047 mm (P<0.05), ağırlıkları 0.0148 ±0.0005 g ve 0.0154 ±0.0005 g (P>0.05)'dır. Merkezin durumu ve annulusların devamlılığı sebebiyle yaş okumalarında kör bölge otoliti tercih edilmelidir. Yaş okumaları bütün ve kırılarak yakılmış kör bölge otolitlerinde yapılmıştır. Abstract: Otolith Structure, Otolith Dimensions-Fish Length Relationships and Age Determination of Fourspotted Megrim Lepidorhombus boscii (Risso, 1810)The core is centric in the fourspotted megrim's blind side otoliths where it is near the posterior area in the ocular side otoliths. Consequently, while the opaque and hiyalin rings were observed both anterior and posterior area on the blind side otoliths, rings were overlapped on the ocular side otoliths, because of having a core nearly posterior area and this made it difficult to follow the continuity of zones. The mean values of the blind and ocular side otoliths were 4.599 ±0.069 mm ve 4.768 ±0.067 mm (P<0.05) in length, 3.285 ±0.043 mm ve 3.511 ±0.047 mm (P<0.05) in width, 0.0148 ±0.0005 g ve 0.0154 ±0.0005 g (P>0.05) in weight respectively. Because of the case of focus and continuity of annuli, the blind side otolith has been prefered in age determination. Age readings have been made in whole and broken-burnt blind side otolith.
