otter shrew
Very LowTechnical/Scientific
Definition
Meaning
A small, semi-aquatic mammal native to Central Africa, resembling a shrew but with otter-like adaptations for swimming.
A term used in zoology for any of the three species in the family Potamogalidae, which are not true shrews but convergent in appearance and lifestyle, adapted to freshwater habitats.
Linguistics
Semantic Notes
The term is a compound noun where 'otter' describes the aquatic habits and 'shrew' describes the superficial resemblance to true shrews (Soricidae). It refers specifically to a distinct taxonomic family.
Dialectal Variation

Conceptual Metaphor
None in common usage.

FAQ
Frequently Asked Questions
No, it is not a true otter. It is a separate family of mammals (Potamogalidae) that has independently evolved similar aquatic adaptations.
They are found only in Central Africa, in and around freshwater streams and rivers in rainforest regions.
It is called a shrew due to a superficial physical resemblance (small size, pointed snout) to true shrews of the family Soricidae, an example of convergent evolution.
Some species, like the giant otter shrew, are considered vulnerable due to habitat loss and pollution, but conservation status varies by species.
