|Crinoid shrimp Hippolyte catagrapha
The first known photograph of this species dates to 2002, taken by Richard Steventon, who unfortunately subsequently forgot about it. Georgina Jones and Sharon Albert re-discovered the species in 2005 and informed Guido Zsilavecz about it. Intrigued, he searched for them and had success, finding numerous specimens, with variable colouration, as shown.
The species is always associated with the elegant feather star Tropiometra carinata, and be found both inside and outside of the crinoid. It occurs from relatively closely inshore in shallow waters to offshore in much deeper water.
In 2006 Tessa Hempson conducted a survey of crinoids as part of her zoology honours degree from the University of Cape Town, to establish what animals live together with crinoids. SURG members were involved in these surveys.
With the assistance of Professor Charles Griffiths, zoology department of UCT, specimens were given to Dr. Cedric d`Udekem d`Acoz, who described this new species in 2007. Named Hippolyte catagrapha, the etymology of catagrapha is as follows:
"Catagrapha is the feminine of the Latin adjective catagraphus, which means painted, coloured, figured. The name alludes to the complex and variable colour pattern of the species."
