Wild Water Shrew Welfare

Water shrews are semi-aquatic mammals with exceptionally high metabolic rates requiring continuous feeding to survive, making habitat quality essential for individual welfare.

Key Facts

Water shrews must eat up to 150% of their body weight daily to maintain metabolism
They hunt aquatic invertebrates, small fish, and amphibians in waterside habitats
Their high metabolism means starvation can occur within hours without adequate food
Water shrews are venomous, injecting venom through saliva to stun prey
Clean, fast-flowing streams with abundant invertebrates provide optimal habitat

Welfare Considerations

Water shrew welfare is critically dependent on continuous access to abundant aquatic prey. Their extreme metabolic rate means any disruption to foraging quickly becomes a welfare emergency, making clean waterway habitats with diverse invertebrate communities essential for individual shrew welfare.

What You Can Do

Support river restoration projects that maintain diverse aquatic invertebrate communities
Advocate for water quality standards that protect shrew foraging habitats
Reduce pesticide use that depletes aquatic invertebrate prey for shrews
