  • Title
    Diversity of planktonic Ostracods (Crustacea: Ostracoda) in the mixed layer of northeastern Arabian Sea during the summer monsoon
    Type
    Journal Article
    Description
    Planktonic ostracods contribute significantly to the biomass of zooplankton in the Arabian Sea with an unusually high density due to swarming.  However, due to the small size, their abundance is often underestimated.  In this paper, the diversity of planktonic ostracods in the mixed layer depth of the northeastern Arabian Sea in relation to environmental parameters during the summer monsoon is presented.  The mean abundance in the mixed layer depth was very high.  About 26 species belonging to 17 genera representing two families were recognized.  Out of this, 25 species belonged to (3 sub families, 16 genera) the order Myodocopa and one to the order Myodocopida.  The dominant species were Cypridina dentata, Euconchoecia aculeata, Conchoecia subarcuata and Orthoconchoecia atlantica.  Cypridina dentata and Euconchoecia aculeata contributed to about 89% of the total abundance.  The results suggest that the distribution and diversity of ostracods were very much influenced by the hydrographic conditions of the Arabian Sea during the summer monsoon.

  • Title
    Behaviour of Short-finned Pilot Whales Globicephala macrorhynchus (Gray, 1846) (Mammalia: Cetartiodactyla: Delphinidae) in the southeastern Arabian Sea
    Type
    Journal Article
    Description
    We report the presence and behaviour of a pod of short-finned pilot whale Globicephala macrorhynchus in the southeastern Arabian Sea. The pod was observed in the southeastern side of Minicoy Island, in the Nine degree channel (09°219′23′′N;74°39′529′′E) on 03.02.2013. Later, on 06.02.2013,the same pod of pilot whales were observed near Kalpeni Island (10°02′402′′N; 73°39′579′′E) 130 km northwest of the previous location. The average length of the whales was estimated as 550 cm and weight as approximately 1200 kg. They were travelling in a northwesterly direction. The pod size of the whales sighted was twelve and several species specific behaviour such as side rolling, spyhopping, lobtailing, peduncle arching and movement patterns such as synchronous travelling and logging could be observed. The occurrence of scars and injuries on the body of four whales in the pod are also reported.

  • Title
    Sperm Whale Physeter macrocephalus stranded at Devbagh beach, Karwar, western coast of India
    Type
    Journal Article
    Description
    A stranding of a single Sperm Whale Physeter macrocephalus was recorded at the Devbag beach (Arabian Sea), Karwar, Karnataka State, on the central west coast of India on 17th September 2009. As it occurred in the hours of darkness, a rescue operation could not be made, resulting in the death of the live-stranded animal. Species identification was carried out using morphometric measurements. Death was found to have resulted from natural causes, the unusually low tide was probably the cause of the stranding.
