A ground-dwelling tarantula associated with terrestrial retreats in seasonally dry parts of western Mexico. Shelter and substrate are central to how the animal uses its space.

Meet Sabrina
Sabrina is the Brachypelma hamorii currently in my care. Her collection portrait is built around the vivid orange knee markings that make her immediately recognisable.

Natural history.
The orange bands across the leg joints are the most immediate visual cue. The abdomen also carries defensive urticating hairs, so observation is safer than handling.
Sabrina is given deep substrate, a secure retreat, and a dry surface with access to water. Her own feeding and molt records appear separately below.
Taxonomy and range
The World Spider Catalog treats Brachypelma hamorii as an accepted Mexican species in the family Theraphosidae. Its taxonomic history matters because animals now identified as B. hamorii were frequently presented under the name B. smithi in older literature and in the hobby.
Burrows, shelter, and activity
Mexican red-knee field records describe terrestrial spiders using deep, silk-lined burrows and natural cavities in seasonally dry country. The retreat buffers heat and moisture and gives the spider a secure daytime refuge; activity is concentrated around the entrance and during lower-light periods. Older ecological accounts do not always separate B. hamorii cleanly from B. smithi, so that limitation should travel with the claim.
Feeding ecology
This is primarily a sit-and-wait predator. Vibrations and close-range sensory cues bring the spider out to seize passing arthropods, which are subdued with the chelicerae and venom before external digestion. Sabrina's feeding records show one animal in captivity and are kept separate from statements about the wild diet.
Defence, senses, and movement
The first response is often stillness or retreat, but the abdomen also carries urticating hairs that can be brushed into the air. Those hairs can irritate skin and eyes; the calm appearance associated with the species is not a reason to handle it.
In my care
Meet Sabrina.
Sabrina is the individual behind this profile. Her orange knee bands make her easy to recognise across the collection, while her own feeding and molt history remains distinct from published species-level information.
