What animal leaves black poo?

Answered by Randy McIntyre

One animal that is known for leaving black poo is the otter. Otters are semi-aquatic mammals that can be found in rivers, lakes, and coastal areas. They have a varied diet consisting mainly of fish, crustaceans, and other aquatic creatures. As a result, their droppings, also known as spraint, are typically coarse and black in color.

The texture of otter spraint is quite distinct, often resembling a tarry substance. It is not uncommon to find fish scales, shell fragments, fish and crayfish parts, and sometimes even feathers or fur within their droppings. This is because otters consume their prey whole, and the undigested parts are passed in their feces.

While the color of otter droppings is generally black, it can vary slightly depending on the diet of the otter and the region in which it resides. Factors such as the type of fish and shellfish available in the habitat can contribute to variations in the appearance of their spraint.

I have personally come across otter spraint during my nature walks along rivers and lakeshores. The distinct black color and the presence of fish scales and other remnants always catch my attention. It’s fascinating to think about the otter’s diet and the diversity of aquatic life that they consume.

Otters are known for leaving black poo, or spraint, which is coarse in texture and contains fish scales, shell fragments, fish and crayfish parts, and occasionally feathers or fur. This unique characteristic of otter droppings is a result of their diet consisting primarily of aquatic creatures.
