(Planariidae, Turbellaria, Platyhelminthes) from the Yenisei River Olesia N. Makhutovaa Galina S. Kalachovaa a *, Nadezhda N. Sushchika,b and Alexander V. Ageevb 50 Akademgorodok, Krasnoyarsk, 660036 Russia b Received 1.06.2009, received in revised form 8.06.2009, accepted 15.06.2009 For the first time the fatty acid content and composition of freshwater planarian Dendrocoelopsis sp. has been studied in a station of the large Siberian River, the Yenisei. The dominant fatty acids were palmitic, oleic, eicosapentaenoic and docosapentaenoic acids. The characteristic feature of planarian fatty acid composition was that ω3 docosapentaenoic acid was 2-10 times higher than docosahexaenoic acid. The average content of ω3 PUFA in the planarian was significantly higher than that of ω6 PUFA, 7.20±1.21 and 1.22±0.22 mg/g of wet weight, respectively. The content of sum ω3 PUFAs which are essential for the nutrition of aquatic organisms of the higher trophic levels in the studied planarian was comparatively high. Keywords: fatty acid, planaria, invertebrate, Turbellaria, Platyhelminthes Introduction Planarians are non-parasitic ancient flatworms, which are common representatives of benthic communities in both freshwater and brackish ponds and rivers worldwide. In rivers with high current velocity they occupy and attach on back sides of stones and pebbles, or on algae thallus. The size of the most of planarians specimen ranges from 3 to 12 mm. These flatworms have two or more eye-spots that can detect intensity of light and very simple nervous system (Dogel, 1975). The nervous system includes the ganglion, located at the head of the © Siberian Federal University. All rights reserved planarian and two nerve cords which connect ganglion to the tail. There are many transverse nerves connected to the nerve cords. Digestive system consists of a mouth, located in the center of the underside of the body, pharynx and gastrovascular cavity. The pharynx connects the mouth to the gastrovascular cavity. The digestive system has three main branches throughout the body that increase assimilation and delivery of nutrients to all tissues (Dogel, 1975). Regeneration processes are active in planarians due to simplicity of the organ systems, therefore, planarians have often been used as an * Corresponding author E-mail address: makhutova@ibp.krasn.ru 1 – 135 – , Institute of Biophysics of Siberian Branch of Russian Academy of Science, Siberian Federal University, 79 Svobodny, Krasnoyarsk, 660041 Russia 1
