- The page saysare one of the driest habitats in the world
- The source says
Grant's golden moles dwell in one of the driest and least productive habitats in the world. They are confined to white coastal sand dunes
- The page saysBy day it burrows 50 cm down into the sand and enters torpor, lowering its metabolism to reduce its energy demands.
- The source says
During the day, E. granti burrows to depths of 50 cm and there enters a daily torpor ... E. granti does not regulate its body, but lowers its metabolism, thus reducing its energy demands.
- The page saysIts nightly surface foraging often exposes it to predators, including spotted eagle-owls, barn owls, and domestic cats and dogs.
- The source says
Due to the nocturnal surface foraging of E. granti, it is often exposed to nocturnal predators ... Known Predators African spotted eagle-owls (Bubo africanus) barn owls (Tyto alba) domestic cats (Felis silvestris) domestic dogs (Canis lupus familiaris)
- The page saysLoose sand caves in behind it, so unlike most moles it keeps no tunnel system. It digs a new burrow each time it moves.
- The source says
does not maintain a permanent tunnel system like most moles because the sand it burrows through collapses behind it ... constructing new burrows each time it moves.
- The page saysweightKg: 0.024
- The source says
with a head and body length and mass ranging from 70 to 85 mm and 16 to 32 g, respectively
Note: battleStats (settle #880); midpoint of the range, between the male (25.3 g) and female (19.8 g) averages - The page saystags: subterranean
- The source says
Grant’s desert golden moles lack external eyes, the eyelids fusing at a young age with the skin covering the eyes then increasing in thickness. Their noses terminate in a hard leathery pad which aids in digging
Note: tag kept (settle #880): reduced eyes and a digging snout, per the tag definition

- The page saysFunctionally blind, the mole hunts by vibration.
- The source says
is a functionally blind, nocturnal insectivore ... the golden mole is able to detect termite colonies and other prey items solely using seismic cues
- The page saysIn the Namib, recordings in the sand suggest it can detect termite colonies and other prey using seismic cues alone.
- The source says
The Namib Desert golden mole (Eremitalpa granti namibensis) ... Both geophone and microphone recordings in the substrate suggest that the golden mole is able to detect termite colonies and other prey items solely using seismic cues.
- The page saysIts malleus, one of the tiny bones inside the middle ear, is hypertrophied, an adaptation for picking up low-frequency signals.
- The source says
This animal exhibits a hypertrophied malleus, an adaptation favoring detection of low-frequency signals.

- The page saysClumps of dune grass, home to its prey, give off low-frequency vibrations that stand out from background noise many meters away, and the mole apparently uses them to orient itself toward the grass.
- The source says
isolated hummocks of dune grass generate low-frequency vibrations, distinct from the background noise at a distance of many meters. The golden mole apparently uses these cues to orient itself toward the hummocks and the prey species within.
- The page saysBy vibration. Field studies in the Namib found that clumps of dune grass, where its prey lives, give off low-frequency vibrations, and its massive malleus suggests an ear adapted to pick up seismic cues like these through bone conduction.
- The source says
Field studies in the Namib desert have shown that isolated hummocks of dune grass generate low-frequency vibrations ... the hummocks and the prey species within. An analysis of middle ear morphology suggests that the massive malleus of the golden mole is adapted toward a form of inertial bone conduction, suitable for the detection of seismic cues obtained in this manner.

- The source says
The malleus density of the desert golden mole Eremitalpa granti (2.44 g/cm3) was found to be higher than that reported in the literature for any other terrestrial mammal ... This high density is expected to augment inertial bone conduction, used for the detection of seismic vibrations
- The page saysThe mole's malleus has been measured at 2.44 grams per cubic centimetre, denser than the equivalent bone in any other land mammal on record.

- The source says
examined the ability of Namib Desert moles to survive on an insect diet without drinking water ... Water independence is achieved through efficient renal function while low rates of energy usage and torpor are further effective in reducing overall water requirements.
- The page saysEfficient kidneys. Studies of Namib moles credit renal function for their independence from drinking water, with low energy use and torpor trimming their needs further.

How the table was made: a writer drafted the profile from these sources and logged each claim with its quote, a reviewer with nothing but this table checked every sentence said no more than its quote, and a script confirmed each quote appears word for word in the source. The method is in the site'sAbout page.
