Pseudorca Crassidens (False Killer Whale)
UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour Pseudorca crassidens (False Killer Whale) Family: Delphinidae (Oceanic Dolphins and Killer Whales) Order: Cetacea (Whales and Dolphins) Class: Mammalia (Mammals) Fig. 1. False killer whale, Pseudorca crassidens. [http://ocean.si.edu/ocean-photos/killer-whale-imposter, downloaded 31 October 2015] TRAITS. Pseudorca crassidens is at the upper size range within its family (Delphinidae); males can be as much as 6.1m and females 4.9m in head and body length (Nowak, 1999). Both sexes weigh in at around 700kg (NOAA Fisheries, 2013) although they can reach a maximum weight of 1360kg (Nowak, 1999). Newly born offspring are typically no longer than 1.8m and are only a fraction of an adult’s weight (Leatherwood, 1988). The false killer whale has a bulb or melon feature on its forehead (Fig. 1) which is slightly larger in males, and a narrow head which tapers into its slightly elongated and rounded snout. The jaws of P. crassidens hold 8-11 pairs of thick teeth and have an overhang, with the upper jaw protruding forward past the lower jaw. The thin sickle shaped dorsal fin of the false killer whale is also slightly tapered and can measure as much as 40cm tall (Leatherwood, 1988; Nowak, 1999). The pectoral flippers have a characteristic UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour shape unique in its family, with a bulge on the front edge. Sexual dimorphism also occurs in the skull with size variation between male and female which measure 58-65cm and 55-59cm respectively.

Previous studies showed that yak (Bos grunniens) rumen microbiome and fermentation differ from other ruminants. However, little is understood on the features of the rumen microbiome that make yak adapted to its unique environmental and dietary conditions.

Differential Expression of Skeletal Muscle Mitochondrial Proteins in Yak, Dzo, and Cattle: a Proteomics-Based Study

Changes in yak mitochondria by natural selection in a hypoxic environment could be utilized to understand adaptation to low-oxygen conditions. Therefore, the differences in proteome profile of skeletal muscle mitochondria from yak, dzo, and cattle were analyzed by mass spectrometry, which were then classified into 3 groups, comparing between yak and dzo, yak and cattle, and dzo and cattle. 376 unique mitochondrial proteins were identified, including 192, 191, and 281 proteins in the yak-dzo, yak-cattle, and dzo-cattle groups, respectively. NRDP1 and COQ8A were expressed at higher levels in yak and dzo compared to those in cattle, indicating higher endurance capacity of yak and dzo in a low-oxygen environment. Gene Ontology (GO) terms of biological processes were significantly enriched in oxidation-reduction process, and that of molecular functions and cellular component were enriched in oxidoreductase activity and the mitochondrion, respectively. The most significantly affected pathways in Kyoto Encyclopedia of J. Vet. Med. Sci. Genes and Genomes (KEGG) analysis were Parkinson’s disease, Huntington’s disease, and oxidative 82(8): 1178–1186, 2020 phosphorylation between the yak-cattle and dzo-cattle groups; while metabolic pathways, citrate cycle, and carbon metabolism were significantly affected pathways in the yak-dzo group.

Several species of animals 7 species of domestic and 9 species of wild animals were found in the region. Famous Photographers of Turtuk valley. Received 14 May, 2021; Revised: 28 May, 2021; Accepted 30 May, 2021 © The author(s) 2021. Published with open access at www.questjournals.org I. INTRODUCTION Turtuk valley is the most beautiful valley of Nubra division of the district Leh (UT LADAKH ) that lies in the bank of shayok river between two huge mountains. The mountains are the source of water and fodder for the livestock . The population of the valley about approximately 1O,000 the valley start from Changmar to Thang . The valley entirely different valley of ladakh there is a great variation in altitude approximately 9000ft above the sea level. In Turtuk valley most of people rearing animals like Sheeps , goats , Cow , Yak , Dzo , Dzomo, Donkey and Horse etc. Wild animals are living in the mountains and valley (Nalla) eg Bogdang nallah, Tebay nallah, Ramdan nallah and Tyakshi nallah etc . II. RESULT AND DISCUSSION Final report 7 species of domestic and 9 species of wild animals were found in Turtuk valley all the recorded animals have been documented in the paper along with their common name, scientific name local name and important roles etc As a result wild species are seen to be threatened in the natural habitat of the study area eg Snowleopard, Tibetan wolf, Eurasian Lynax, and Ladakh Urial etc.
