Asian Small-Clawed Otter - The Basics!

Asian Small-Clawed Otter
(Aonyx cinereus)


As promised, the posts this week are brief overviews of EACH of the otter species, focusing on recent information about each species and a vid or 2...
This is the 3rd of the 3 otter species that are found *only* in Asia, !


The Asian Small-Clawed Otter is the smallest of all otter species, and also, arguably, the most social. They mate for life, and live in family groups of between four and twelve, and sometimes up to twenty, otters. The group hunts, plays, and sleeps together. These otters will travel a long distance out of water in search of new habitats. They don't generally dive deeper than their body length in search of food, and spend more time out of the water than most otter species.

(Was also known as Oriental Small-Clawed Otter).

Status: Vulnerable and Decreasing 


The areas in yellow on the map below show where the Asian Small-Clawed Otter lives in southeast Asia. Despite how adaptable they are, they have become extinct in large parts of their original range.



Asian Small-Clawed Otters are very social and gregarious, watch and see for yourself!

Here are a few clips of a family group kept at woodland Park Zoo (who participates in the Species Survival Plan):

Smooth Coated Otter - The Basics!


Smooth Coated Otter 
(Lutrogale perspicillata)


As promised, the posts this week are brief overviews of EACH of the otter species, focusing on recent information about each species and a vid or 2...
 
This is one of the 3 otter species that are found *only* in Asia, !


  
The Smooth Coated Otter prefers to live in undisturbed areas. They tend to be nocturnal, sometimes hunting alone and sometimes in large groups. Smooth Coated Otters mate for life, and live in family groups consisting of the mated pair and their pups (often including full-grown pups). Research demonstrates that the alpha female is dominant and determines hierarchy within the group, while the alpha male moves the group through their territory. Smooth Coated Otters are proficient both on land and in water. They are powerful swimmers, and on land they climb and jump quite well.

Status: Vulnerable and Decreasing


The Smooth-Coated Otter (in rust on the map below) is found through southern and southeastern Asia, with an apparently isolated population southern Iraq (it's current status throughout the rest of the Middle East is currently unknown).



Even though they tend to be nocturnal, there are some really good videos of smooth-coated otters:
