Many otters have been observed chomping on fish through the lens of avid photographers before.

Like this one:

Awww so cute.

What we don't get to see as often is the action during the catch which we now can view from rare footages uploaded by one otter enthusiast, Alvin Tan on Aug.27:

Look how the Bishan otters danced around the fishes, maneuvered around each other, so that everyone can get a bite.

According to the OtterWatch, what appeared to be rather haphazard and messy is actually more coordinated than you think:

Here's the post today, Sep.2, explaining the behaviour with a sleek shot of the Pasir Ris otters:

The otter family often work together by rounding up the fishes. This herding method is pretty interesting to watch. Every otter seems to know their "position" and expected action when they are at the position.

The first and last otter would normally moved in faster so that the line of otters could form an Arch cornering the fishes. And this would cause the fishes to panic and leap into the air or onto shore or rock. Otters would then them pick them up.

Quite an amazing sight seeing wild otters going after their catch.

This is the Pasir Ris family.

Neat. Science lesson right there.
