TUBE FEET, RAYS, SPINES & OSCICLES
This is the business end of a BRITTLE STAR, one of 1,600 species of the Class Ophiuroids.
It, as most in this class, is pentamerous, having body parts in multiples of five or body parts in numbers divisible by five.
In this image one can see five rays (legs) the little yellow "tube feet", the spines on the rays & the oscicles or plates modified for rasping encrusting coraline off of live rock. There are five sets of these plates, at the base of five bulbous smooth projections between each of the five rays.
If you ever see one, give it a high five.
A man was married on the fith day of the fifth month, in 1955. He had five daughters. He worked for fifty years at an insurance company on 5th ave. on the fifth floor. When he retired he received a $5,000.00 bonus. Knowing he had been involved in the number five all his life, he went to the racetrack, to make a wager.
He bet the fifth horse in the fifth race which incidently paid five to one.
His horse came in fifth.
