Formerly referred to as "Anomalocaris" briggsi, it was placed in the new monotypic genus Echidnacaris in 2023. [1] It is only distantly related to true Anomalocaris, and is instead placed in the family Tamisiocarididae. [2] Echidnacaris is primarily known from its frontal appendages which had 13 podomeres.

[46] According to a study of an Australian cohort, between 1985 and 2015, the average life expectancy of a person with scleroderma increased from 66 years to 74 years (the average Australian life expectancy increased from 76 to 82 years in the same period).

Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye.

Cockayne syndrome is a rare but destructive disease usually resulting in death within the first or second decade of life. The mutation of specific genes in Cockayne syndrome is known, but the widespread effects and its relationship with DNA repair is yet to be well understood. [6]
