Pyrenean desman

The Pyrenean desman is a small, semi-aquatic mammal closely related to moles and shrews. It is one of only two surviving members of the Desmanini tribe and faces significant threats worldwide. This unique creature is found in parts of Spain, Portugal, the French Pyrenees, and Andorra, though its range has been substantially diminishing.

Measuring between 11 to 14 centimeters in length, with a tail adding another 12 to 16 centimeters, the Pyrenean desman weighs merely 35 to 80 grams. It possesses some fascinating adaptations: a sensitive snout with vibrissae (whiskers), webbed feet for swimming, and the ability to close its nostrils and ears when underwater.

Covered in dark, brownish fur, the Pyrenean desman uses its black nose, which is lined with whiskers, to detect prey. It primarily feeds on small invertebrates and can breed up to three times a year, typically having three to four young per litter. Mostly nocturnal, these creatures can exhibit aggression towards other adults of their species.

They prefer fast-flowing rivers with shallow waters and lush riparian vegetation but are increasingly threatened by habitat fragmentation, invasive species, and climate change. Recent studies indicate a decline in their populations.

Interestingly, the Pyrenean desman was the 8,000th animal photographed for Joel Sartore's "The Photo Ark" as featured by National Geographic.
