The heart rate of one species, the Masked Shrew, has been recorded at beats a minute, faster than that of the hummingbird. However shrews, being the oddballs that they are, lose their deciduous teeth while still in utero and thus are born with a full set of permanent teeth!
So not only are they voracious eaters but they only have one set of useable teeth for their entire eating life. If their teeth wear down to the point of being inefficient for chewing, they would then starve to death. This is seen in the dark reddish coloration on the teeth. I was searching for the answer… Why shrew is weaker than mouse? They can survive without food for few hours, whereas mouse can survive for days.
Thank you so much for such a great, informative article! I live in Northumberland, UK, and have recently built a tiny wildlife pond. I was just sitting quietly by it, when all of a sudden, two shrews shot out from underneath one of the rocks, it looked as if they were chasing each other. One fell into the pond, swam a couple of laps, then dived out and back under the rock!
I was wondering if this is usual? I love this article. Have you got anything to say about shrew family behaviour? I walked onto my back deck in New Jersey early on a September morning, when it was still fully dark. I put the deck lights on. I soon observed a small creature jumping around in the cut lawn surrounding the deck. At first I thought it was a small frog. It repeatedly moved in wide for it circles, very rapidly. After making such circles in the turf, it hid out a bit, taking a break.
At that point I soon was able to see it, identifying it as a very tiny mouse-like creature, i. I concluded that both behaviors were designed to flush insect-prey out. But there was no success in this that I could identify.
It often appears from behind the cooked and seems is becoming quite confident even when there are people around. Hi, many years ago I got bitten on the side of the right foot by a shrew, and the area became itchy for years after that, and so decided to try acupuncture on it. Therapist put needles around the area and thankfully made the itch go away.
However in the last three months the itch has come again, any scratching on area does not resolve it. Now that shrew bit me about 20 years ago!
A great and wonderful piece. I would be hard pressed to describe what I liked about it most, whether it was the exposure of a magical and magnificent example of the genius that is Nature, contained in something so ordinary and commonplace as the shrew, or the idea of your final paper.
Which brings me to my question-when do I get to read it? Thank you for your comment, Paul. I am glad you enjoyed the story. As far as my paper, I am afraid it has been lost to time. There are several papers and notebooks from that era of my life I now wish I had…. Nice Post. My son just sent me a picture in a text message of a couple rodents his cat deposited on his doorstep.
At first I took them to be voles but on closer inspection the sharp noses spoke loudly shrew. So, I told him to give his cat a good looking over for festering swelling bites. Right away he mentioned that the cat did seem to have some issues and as a PA decided to give the cat a good look over. Next day he sent me a picture of lacerations that look like they came from a surgical scissors.
That was after he thoroughly cleaned out the wounds. Yep classic shrew bit. He also reported the wounds to have a pretty fowel odor about them. Hi Matt, This is an interesting read. A mammal with venom! I also encountered The Taming of the Shrew in college class and enjoyed it immensely and would like to know how you compared Kate to the little critter. I hope I am not the only commenter. Best regards. My house somehow got infested with these lil…… And the smell is horrid.
As soon as you open the door to my home the stentch hits ya and takes your breath away. What can i do to get the smell out. I have to wash my clothes 3 times in order to get clean smelling. Hi Matthew, We live in Kansas. Last week my husband and I were watching a scary movie. Out of the corner of his eye, he caught a glimpse of a black oval object go under the other couch. I shrugged it off to imagination. The next night I saw it, the high rate of speed and it was jet black led me to believe this is not a mouse.
So before bed I set a cracker in front of the couch we saw it run under. The next morning it was gone. How do I get rid of it? I set 2 mouse traps. The food was gone on one of them and the trap was still set.
Speedy Gonzalez the fasted mouse of all Mexico came to mind. We keep a clean house, we think it may have snuck in under the storm door when the weather was nice. Great article. I really enjoyed reading and learning more about these creatures that I recently caught inside my home and seen for the first time in my 43 years. I had a rodent problem for years and eventually erradicated them but shrews have now moved into their holes, probably to feed off the insects of the decaying rats.
Should I try to eliminate the shrews or will they keep the rats away? I threw the dead animal into an adjacent field. The next day, we found a dead shrew in the same tree….??? We see night hawks in the area…now other hawks or eagles. Ohio here, I have a shrew that lives in our garage. He is dusty dark grey and has been munching on cat foot daily for about 2 to 3 yrs now I have enjoyed his antics I watch him daily as I have a bad habit and smoke in the garage.
They are so fascinating and yes constantly gathering food I have even seen him eat out of the same dish with our cat we have 4 they leave him alone. I understand now it must be the musty smell. I have tons of video he currently seems to take food to three locations? I here the fighting sometimes high squeeks almost like yelling at each other as a warning sometime and know the location of the nest.
I Give him a brake some days and put the food right next to his nest … because he dose gather allllllll day long minus a few naps! Thank you so much. We continue to save and release shrews from our cat. My goodness they are shrill and clever.
We have watched them play dead and run. Clever and resilient little creatures. Well done on this article! My cat caught a shrew tonight through the chicken wire enclosure and I wanted to know more about them.
Glad you got an A on your paper! Hello, thoroughly enjoyed reading your blog as found a dead Shrew frozen on my path in Cornwall UK.
This prompted me to research this little mammal. I love nature and have now learnt about my little Shrew thank you. May the little soul RIP bless. Very interesting facts about shrews. I caught a mouse-like creature in my basement in Maryland that we think is a shrew. Can I send you a picture for an ID? I consider myself an observant person in nature, spending years learning different native species of plants, foraging edible berries, and novice-level mushroom hunting.
I remember that shrew so fondly, voraciously eating something it had found and paying no attention to my presence. Thanks for this blog post! Thanks for your information. I had a couple traps for mice in the house and when a trap was sprung and subsequently disappeared, I wondered what sorcery was this?! Turns out a shrew moved in also. I actually began talking to the little bugger as he made an appearance now and then, darting here and there as if lost before returning to a dark haven once more.
I had been on the verge of naming the intruder when he was finally trapped and killed last night. Though relieved, I felt a little bad for him. I was impressed with his soft coat but there were his greatly diminished eyes slits! I wondered if he had been blind, but he reminded me so much of a mole I had to begin the Google search and found your blog. Very interesting — thank you. Great piece. Thanks eversomuch. Small creatures: the loudest chattering we heard in Central Park was i discovered a tiny chipmunk six feet from our walking path.
Was it annoyed or calling out? But the rest of the group was scoping for a larger animal possible on a tree branch. There must be a shrew or two in Central Park tho. In 2 separate incedents over a 2 week period I found dead short tail shrews under my bird feeder in almost the same exact spot. Thank you for this very informative and fun information. I live in northern Oregon-and saw my first one today! But I have to say I had literally no idea just how amazing they are.
For example do they really have stomachs?? She is recognised as one of if not.. So my absolute aim is to try and get her voice shared on social media e.

Abstract The American shrew-mole Neurotrichus gibbsii seems to occupy an ecological and evolutionary position intermediate to that of shrews and fully fossorial moles. Open in new tab Download slide. The animals were then released back into the wild. This all led to an exciting discovery. The measurements revealed that the animals' metabolism is equally active in summer and winter.
Animals that do not hibernate usually require more energy in winter in order to maintain a constant body temperature. This gives shrews a survival advantage that has likely enabled them to colonize colder regions. Common shrews have one of the highest metabolic rates among mammals. They must therefore consume a considerable amount of energy for their relatively low body weight. Because their fat reserves are quickly used up, they often starve to death after only a few hours without food.
Nevertheless, forest shrews and their close relatives are highly evolutionarily successful and quite widespread, especially in the northern hemisphere. Dina Dechmann, a scientist at the Max Planck Institute of Animal Behavior in Radolfzell, hopes to find out how animals deal with large fluctuations in food supply and other resources. For example, how do tiny shrews manage to overcome the cold and food shortages in winter? But studies with wild shrews consume a great deal of time and resources.
Because of their strong territorial behaviour, the animals must be kept in large individual enclosures throughout the experiments.
