They rest on sandy riverbanks and establish their dens under tree roots or among boulders. All smooth-coated otter artwork ships within 48 hours and includes a 30-day money-back guarantee. They can generally be found in areas where there is not a lot of human habitation. A camera trap captures a family of smooth-coated otters. The resulting offspring and their descendants bred back into the smooth-coated otter population, but maintained the genes of their small-clawed otter ancestors. Lutra perspicillata was the scientific name proposed by Étienne Geoffroy Saint-Hilaire in 1826 for a brown otter collected in Sumatra. River otter species hunt and travel in the water, but frequently rest and play on land. 7. Otter of the Franklin books and Animated Adaptation is shown as being this. [8], In southern Bangladesh, smooth-coated otters are used for commercial fishing. The reclaimed khazan lands in particular, which are under perennial threat of being overrun by the mangroves that originally owned them, are the subject of a constant tug of war. Smooth-coated otters rolling in the dirt. They also com­mu­ni­cate throu… “It is an exciting time for drones in general and specifically for conservation work,” he added, “because there’s so much potential to help save wildlife and the environment.”. Thus, the adaptability of Smooth‐coated otters … Its tail is flattened, in contrast to the more rounded tails of other otters. It is distinguished from other otter species by its more rounded head and a hairless nose in the shape of a distorted diamond. “There are statistical operations you can use which will allow you to identify which pixels in a particular image are vegetation, which are open water, and so on,” Srinivasan said. It is found throughout the Indian subcontinent and in south-east Asia. A good year for the Philippine eagle in 2020, but not for its supporters, Colombian and Ecuadorian Indigenous communities live in fear as drug traffickers invade, Lack of protection leaves Spain-size swath of Brazilian Amazon up for grabs, How can Southeast Asia benefit from the new U.S. policy on illegal fishing? We show that smooth-coated otters in Singapore are L. perspicillata x A. cinereus hybrids with A. cinereus mtDNA, the first reported case of hybridization in the wild among otters. The smooth-coated otter is a member of the weasel family, Mustelidae, in the Mammalian Order of Carnivora. “We choose the middle ground in terms of price, because functionality is decent and you don’t feel too much of a pinch if they are stolen,” Fernandez said. 9. It is listed as Vulnerable on the IUCN Red List since 1996 and is threatened by habitat loss, pollution of wetlands and poaching for the illegal wildlife trade. They may be distinguished from other species of otter by a more rounded head and a hairless nose in the shape of a distorted diamond. “We’re always wary of putting cameras in new places and very public spaces,” Fernandez said. Along the Chambal Riverin India, smooth-coated otters are most vulner… [10][16], In Kuala Selangor Nature Park, an otter group was observed hunting. In the 19th and 20th centuries, several zoological specimens were described, including: gaps under buildings) as alternatives for their holts, and learnt to use man-made structures such as staircases and ladders to get in and out of concrete canals with vertical or near‐vertical banks. Ringed seals are Few people picture a trek to the Arctic circle, but this is the ideal environment for a ringed seal. “There’s not much written about smooth-coated otters in mangroves…especially in a human-dominated landscape,” said Katrina Fernandez, a member of the IUCN Otter Specialist Group and director of Wild Otters Research (WOR), a research and conservation organization. Across the years I have made several notes on its behavior, adaptation, family dynamics, interaction with humans, interaction with stray dogs, interaction with other wild animals, habitat selection and habitat use. And the testing validated that we can actually put a project together around this.”. Lutrogale was proposed as generic name by John Edward Gray in 1865 for otters with a convex forehead and nose, using perspicillata as type species. Also, it’s quite hard to tell what the actual habitat is from the satellite image alone,” said Sophie Darnton, a research intern with WOR. The fur is mostly dark with yellow or white markings on the chin and neck, while their feet have claws and webbing. 2008). “At some point, I want to look into just manufacturing our own,” she added. The smooth-coated otter is threatened by poaching, loss and destruction of wetlands, as these are converted for settlements, agriculture and hydroelectric projects; water courses are being polluted by pesticides such as chlorinated hydrocarbons and organophosphates. Natural History/Description. We examined patterns of habitat occupancy and intensity of habitat use by Asian small-clawed otters (Aonyx cinerea) by sampling 59 hill stream segments in the Western Ghats between February and April 2008, using spraints (otter feces) as an indicator.We used an occupancy-based approach to determine the influence of habitat covariates on detection and occupancy. Hartley R., 2011 had mentioned that as a social animal, the smooth-coated otter lives in family groups consisting of a male, dominant female and cubs. Two species, the Asian small-clawed otter (Aonyx cinerea) and the smooth-coated otter (Lutrogale perspicillata), were involved. “You get a much more holistic view of an area when you have both groundwork and drone-imagery and satellite imagery on top of that,” said Shashank Srinivasan, director of Technology for Wildlife. Our EIN or tax ID is 45-3714703. “When you create a 3D model, can you ascertain the height of a dyke, can you use a bunch of analysis techniques to distinguish between vegetation and open water and even different kinds of vegetation? Another lineage contained ... Lutrogale p. sindica holds the palest fur, likely an adaptation to the arid nature of its habitat, with the general hue of the upper side being tawny or sandy brown instead of darker brown with a rusty ( Read how hundreds of wild parrots have flocked to this Brazilian city .) This is the Asian small-clawed otter ... but this adaptation is a useful one for the otters in general. The need to frequently change batteries and the lack of high-quality microphones on these cameras are also pain points for the researchers. The techniques involved—photogrammetry, making measurements from a set of overlapping images for 3D models and orthomosaics, creating overlapped, geometrically corrected aerial images for 2D maps—essentially boil down to extracting meaning from the individual pixels in the images. For example, the otters routinely make dens on the banks separating the khazans from the estuary and scale the retaining walls of these banks to defecate and to groom themselves. Otter, any of 13–14 species of semiaquatic mammals that belong to the weasel family and are noted for their playfulness. Since the last issue, we have welcomed 10 new members to the OSG, and welcomed back a former member: you can read more about them on the Members-Only pages..

[2], Smooth-coated otters were observed to forage on river banks among tree trunks. 2. Mildly, in the sense that they form small family groups. The elusive European otter (Lutra lutra) has sleek brown fur, which is often paler on the underside, and a long lithe body with a thick tail and short legs.Adaptations for an aquatic lifestyle include webbed feet, the ability to close the small ears and the nose when under water, and very dense, short fur which traps a layer of air to insulate the animal. Among mustelids, otters have evolved two feeding specializations: underwater raptorial capture of prey (mouth-oriented) and capture of prey by hand (hand-oriented), both of which have likely associations with morphology and bite … “It’s easy to fly a drone but much harder to create meaning from the data,” he told Mongabay. perspicillata, smooth-coated otter) and Africa (Aonyx capensis, African clawless otter). If you want to post a public comment, you can do that at the bottom of the page. To improve their understanding of these effects, the Wild Otters researchers are incorporating new technologies to help them map the Chorao landscape and document its changing land-use patterns. “If we decided to use a satellite image, it might be a bit out of date. It is possible to introduce to each other at all age; it is infinitely more successful when the otters are young (IUCN/SSC, 2008). The otter is lithe and slender with short legs, a strong neck, and a long flat tail that helps propel it gracefully through water. [9], The smooth-coated otter has been recorded in Pakistan, India, Nepal, Bhutan, Bangladesh, southwest China, Myanmar, Thailand, Vietnam, Malaysia, Singapore, Indonesian islands of Borneo, Sumatra and Java, and Brunei. Since it is only known from about 30 specimens in zoological collections, it had been listed as Data Deficient on the IUCN Red List since 1996, as it is considered one of Africa's rarest carnivores. Where it is the only occurring otter species, it lives in almost any suitable habitat. Asian small-clawed otter (Aonyx cinereus) (Photo credit: The smooth-coated otter and the Asian small-clawed otter genetically diverged about 1.33 ± 0.78 million years ago. During the rice planting season, they also hunt rats in rice fields. They are a mildly social animal. Srinivasan said the results of the pilot study suggested that drone mapping can replace many components of traditional fieldwork. Theft and displacement by curious locals also threaten the cameras. The charismatic otter, a member of the weasel family, is found on every continent except Australia and Antarctica. Trapping of otters is prevalent in India, Nepal, and Bangladesh. In that way, drone imagery is very complementary to ground-based work, and it really fills a gap in the entire process.”. Smooth coated otter is called "Oodh Balao" in Urdu language and the sub-species found in Pakistan is known as Sindh otter. [10], The population in the Mesopotamian Marshes was feared to have perished, but otter tracks were found in 2009, suggesting the population may have survived. They are well known for the luxurious hair that they have. It is very silky in appearance as well as to the touch. In this formation, they undulated wildly through the creek, causing panic‑stricken fish to jump out of the water a few metres ahead. [19], So long as the food supply is sufficient, they breed throughout the year, but where otters are dependent on monsoons for precipitation, breeding occurs between October and February. As the name suggests, these Otters don’t have claws. 22, Issue. The smooth-coated otter has a short and sleek fur that is dark to reddish brown along the back, but light brown to almost grey on the underside.

Local residents cut, burn, and/or remove what they see as invasive vegetation using earthmovers to maintain the economic viability of these lands. [23] Variation in terrestrial mammalian skull morphology is known to constrain feeding performance, which in turn influences dietary habits and ultimately fitness. Smooth-coated otters have both physical and behavioral adaptationsor features that help them survive in their environment. [21] Smooth-coated otters don’t see very well in the dark, and most peninsular Indian rivers have murky waters. Copulation occurs in water and lasts less than one minute. Infanticide could be an adaptation that (1) increases resource acquisition (cannibalism), (2) excludes competitors for the agent or its kin, (3) increases the inclusive fitness of one or both parents, or (4) increases the reproductive success of adult males unrelated to the infant. [17], Smooth-coated otters form small family groups of a mated pair with up to four offspring from previous seasons. Knowing which actions of the human community are affecting the animal and which are not is paramount to any realistic conservation efforts.”. The natives call this otter fisi maji, which means “water hyena” in Swahili. They are mainly di­ur­nal, and have a short lull in ac­tiv­ity dur­ing midday.

An isolated population exists in Iraq.These otters are highly adaptable to various habitats. Although it is often found in saltwater near the coast, especially on smaller islands, it requires a nearby source of fresh water. “If you can know the extent to which this species can adapt and survive, then you can direct human activity in the right way. They may either construct such a burrow themselves, or they may take over an abandoned one. They walk several survey routes on the island using GPS devices to manually record the extents of different vegetation types, areas frequented by otters, and other points of interest, including sluice gates, farms, and fishing areas. They mark their playground by urinating and sprainting on rocks or vegetation. Previously, smooth-coated otters were mostly sighted in the mangroves, mudflats and coastal areas such as Sungei Buloh Wetland Reserve, Pasir Ris, … The mothers give birth to and raise their young in a burrow near water.

Snakes, amphibians and insects constitute a small portion of their diet. Smooth Coated Otter. They spend the night in dens dug in dense vegetation, under tree roots, or among boulders. WOR also collaborated with Technology for Wildlife, a geospatial data company helping groups use technology to conserve wildlife and the environment, to carry out a drone mapping pilot study in Chorao in May and June of 2018. [1], It occurs in areas where fresh water is plentiful — wetlands and seasonal swamps, rivers, lakes, and rice paddies. The other interesting fact about otters is that a single romp can have a large home range (what we now term an ‘otter corridor’).
