Otters are well known for their playfulness and sense of curiosity. Playing together helps keep family bonds strong and teaches the pups important skills such as how to find food. Otters have many sounds to communicate with, including different sounds for greeting, playing, courting and even a special call for raising the alarm! The otter’s great sense of smell also allows them to communicate using scent marks.
The Sea Otter lives in the cold coastal waters of the Pacific and spends most of its time out in the water. The Sea Otter has no blubber so keeps the cold at bay with the thickets fur in the world — around 150,000 hairs per square centimetre!
Perhaps because of their playful nature, otters have become part of myths and stories from cultures from all around the world. On a more practical level, small-clawed otters are traditionally trained in parts of India, China and South-east Asia to help fishermen: catching fish and returning them to the boat in exchange for a reward. Unfortunately, the relationship between otters and humans has not always been so mutual — otters have been hunted for their fur for hundreds of years.
Sadly, 12 out of 13 of the Otter species worldwide are under threat or endangered. Their numbers are declining due to reasons including hunting otters for the illegal fur trade, habitat destruction and reduction in available prey. They are also affected by pollution of waterways, including pesticide run-off from farmland. Water pollution and overfishing reduce the availability of prey species, such as crabs, that the otters eat.
Otters love water. So, they are found on the shores of rivers, lochs, waterways and coastal areas. The population is booming across Scotland after being pushed close to extinction back in mid 1900s. Relative to the UK, Scotland has a high proportion of the population, particularly on the western coast and islands. They are a protected species.
Whilst numbers are growing, they can still be difficult to spot. They spend most of their time in the water and sleep and breed in holts, which are normally caves, burrows or holes. Otters are not specifically nocturnal, but they are typically more active at night.
Otters need to eat at least 1kg of food per day and get most of their food from the water. Their fantastic swimming skills, waterproof fur, rudder-like tail and webbed feet make them brilliant aquatic hunters, and otters typically feed on fish, frogs and crustaceans. They also prey on birds and mammals on waterfronts.
Whilst otters are protected, they can get injured by snares, which may be set for pest control but indiscriminately harm lots of wildlife and domestic animals. The Scottish SPCA supports a complete ban on the use of snares.
Otters under a year old would not survive in the wild, so any youngsters need support. If a baby otter’s mother is killed or scared off, it will not be able to fend for itself. Many of the otters we rescue are babies, and come to our National Wildlife Rescue Centre where they stay until they are of age to make it on their own.
If you come across an otter cub that’s calling for its mother, observe it from a distance for a while if the cub is in a safe place. If the mother does not return within an hour or two or before dark, the cub needs to come in to our care. At that point, you should call our animal helpline on 03000 999 999.
We’ve successfully hand-reared and released lots of cubs back in to the wild over the years.
As baby otters are dependent on their parents for a year, we need to look after them for months. We try to time a release with when they would naturally leave their parents to find their own home. Any release is meticulously planned and takes in to account landowner permission, the population of other otters in the area and suitability for the species to have a long and happy life.
There is no cuter sight than an otter floating around on its back with its little paws folded on its belly. They look like aquatic teddy bears from a distance, but if you get up close, you soon realize not everything about the otter is quite so adorable.
Despite that, the demand for pet otters is soaring, and it’s not doing the otter any favors. Asian small-clawed otters are highly sought after both as pets and for the increasingly popular otter cafes.
Even some of those who own pet otters advise others against it, and we’re going to find out why. Not only that, but we’re going to explore the otter’s natural habitat and its origins.
You’d expect otters and beavers to be closely related; after all, they’re both furry creatures that spend large portions of their day in the water. Weirdly enough, however, they don’t even belong to the same family.
In fact, you could say they’re otterly different! While both are mammals, otters are carnivorous and more closely related to the weasel.
Would you believe there are 13 different otter species, which are divided into two distinct groups – river otters and sea otters? The lutra genus contains all the world’s river otters, while sea otters belong to the Enhydra genus.
Wild otters all have a few things in common, including their basic physiology and love of water. With their dense fur coats and webbed feet, they are perfectly adapted to an aquatic environment and spend most of their time in the water.
Buy OttersEven with that thick fur, otters have had to make physiological adaptations so they can keep warm. Sea otters live in the cold waters of the North Atlantic and rely on their fast metabolisms to generate enough heat to stay warm.
Another characteristic shared by all otter species is that they are one of the few animals to have inbuilt pockets! Under their forearms, otters have flaps of skin into which they can stash food and useful tools like rocks.
They can’t fit a cell phone in there yet, but who knows where evolution’s headed?
Despite its adorable appearance, the otter can be surprisingly merciless and violent if the situation demands it. Studies have discovered a nasty side to the sea otter, with scientists observing males harassing and sexually interacting with young harbor seals.
Even when reproducing with their own kind, male sea otters are so violent that the trauma can prove fatal for their partners.
River otters aren’t much better and will defend their territories aggressively if provoked. There are even reports of them attacking humans, crocodiles, and alligators!
Of course, there is an otter side to the story (excuse the pun!), and that’s the critical role otters play in their aquatic ecosystems. As apex predators, river otters control the populations of their prey species.

Without sea otters, sea urchins would proliferate, destroying the kelp forests that absorb and sequester so much of the world’s carbon.
Is the Lifespan of the Pet Otter the Same as that of Wild Animals?
Wild animals face numerous threats, from predators to disease, which is why domesticated animals often survive longer.
This is no different for the otter, and pet otters can survive for up to 20 years, while those in the wild have a life expectancy of between 10 to 15 years.
That’s hardly surprising when you consider that mortality for river otter pups sits at over 50% in their second year and that significant numbers of female sea otters die from the injuries the males inflict during mating.
That doesn’t mean finding yourself a pet otter is the best way of protecting the species, and I’ll explain why a little later on.
Playing the mating game for a female sea otter is a painful experience that often ends with her having a bloody, swollen nose.
Male sea otters often hold onto their partner’s nose with their teeth to keep themselves in position.
River otters don’t seem quite so aggressive and will even mate on land if they’re feeling particularly brazen.

Warum sollten Sie Ihren höhenverstellbarer schreibtisch gestell anpassen?
ردحذفIhre Arme, Handgelenke und Hände sollten sich im Ruhezustand im Stehen in einer hängenden Position befinden. Stellen Sie daher Ihren höhenverstellbarer eckschreibtisch auf diese Höhe. Allerdings ist auch die hier beschriebene ergonomische 90-Grad-Konfiguration mit Armlehnen nicht die ideale Wahl.
Kopf, Hals, Beine, Arme und Handgelenke des Benutzers können bei der Bestimmung der idealen Höhe für einen kleinen Stehschreibtisch berücksichtigt werden. Wenn Ihr Arbeitsplatz zu niedrig ist, besteht die Gefahr schwerer Handgelenks-, Ellbogen- und Schulterverletzungen. Ihre Ellbogen sollten einen 90-Grad-Winkel zum Boden bilden.
Die ideale Höhe Ihres Steharbeitsplatzes kann durch Ihre Schuhe beeinflusst werden. Beispielsweise könnte sich jemand dafür entscheiden, an einem Tag Absätze und am nächsten Turnschuhe zu tragen. Der Schreibtisch muss daher zwei unterschiedliche Höhen oder einen L-förmigen höhenverstellbarer eckschreibtisch haben. Erwägen Sie die Anschaffung eines computertisch höhenverstellbar mit Höhenrückruftasten auf der Fernbedienung, wenn Sie feststellen, dass Sie Ihre Körpergröße wiederholt ändern.
Wenn Sie aus dem Fenster starren, achten Sie darauf, dass Ihre Augen dort bleiben, wo sie sich natürlicherweise bewegen: am oberen Bildschirmrand. Stellen Sie Ihren Monitorständer auf etwas Altpapier, um die perfekte Höhe für eine ergonomische Nutzung zu erreichen.
Bei den meisten Steharbeitsplätzen müssen die gleichen Schritte befolgt werden. Unabhängig davon, ob Sie lieber sitzen oder stehen, können Sie mithilfe der höhenverstellbarer eckschreibtisch-Höhentabelle außerdem die Proportionen für die Höhe Ihres Stuhls, Ihrer Tastatur und Ihres Displays abschätzen.
