OPHIUOROIDEA AND CRINOIDEA 



There are numerous species of ofiurs and crinoids in the Red 

 Sea. The ofiurs, which are like serpentine star-fish or 

 charming hairy spiders, are most firequently found in the 

 cavities of the coral. The best way of collecting them is to 

 lift any block of coral from the sea-floor, take this on to dry 

 land, split it with a hammer and then lift them out from the 

 crevices. 



Crinoids are often seen underwater, attached to the tops of 

 the coral. They may be yellow, brown or reddish. They sway 

 gently in the current like flowers with numerous tufted stems.
