[1] Due to their unique appearance and certain characteristics, they make an easy to care for pet or display insect for entomologists and hobbyists.

[3] B. craniifer is potential prey for both invertebrates, such as spiders, mantids, centipedes, and parasitoid wasps, and vertebrate insectivorous animals, including fish, amphibians, reptiles, birds and mammals.

[4] In response to a predator approaching or after an attack, B. craniifer burrows itself into softer substrates when possible, using its head and pronotum, allowing the cockroach to hide.

[clarification needed] Cockroaches, including B. craniifer, are known to possess independent pulsatile circulatory organs within their antennae, also known as an antennal heart.

[9] While the female emits the sex pheromones from pygidial glands, which are located posteriorly on the abdomen,[10] she will also assume a calling posture.

A close relationship is known to exist between the release of these pheromonal signals from specific glands and the corresponding behaviours of female calling posture and male wing raising.

[9] The spermatophore is made by the male inside the females' genital atrium, which is rejected by her multiple days later due to the secretions of her spermathecal glands.
