The Cape dune mole-rat (Bathyergus suillus) is a species of solitary burrowing rodent in the family Bathyergidae. It is endemic to South Africa and named for the Cape of Good Hope.

Males are generally much heavier than females, weighing anything from 570 to 1,350 grams (20 to 48 oz), compared with typical female weights of 590 to 970 grams (21 to 34 oz).
Both sexes are sturdy, large-bodied rodents, with blunt snouts, cylindrical torsos and short limbs. The forefeet are heavily adapted for digging, with powerful curved claws. To enable to move more quickly through tight tunnels, the body has few visible external features; for example, there are no pinnae or scrotum, and the penis retracts into a concealed sheath. Lip-like flaps of skin are able to close behind the incisors, preventing soil from falling into the mouth. The eyes are small, but not permanently closed.

Possible
About 20% of wildlife watchers report a Cape Dune Mole Rat sighting in Cape Town on a given day, based on 211 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 29 mammals we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April and June–November
In those months about 20% of wildlife watchers report a Cape Dune Mole Rat in Cape Town on a given day, against about 10% in May and December–March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Cape Dune Mole Rat sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Cape Town, in our data
Cape Town is the only city on Wallace's Line with enough records to rate Cape Dune Mole Rat sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cape Dune Mole Rat is recorded against all the mammals logged in Cape Town (211 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
