The capacity of a star-fish

commonly manifested. Asingle

a type as the common five- 
fingered species, can reproduce 
its body and the remaining four

Reef, smoked, and sent to the Chinese market such mutilation tending to the

In the matter of colour-ornamentation the Star-fish group is richly endowed. Allusion 
to the brilliant crimson and pink-and-white tints of the British sun star-fish has been 
already made. As with most animal groups, however, it is amid their tropical representatives 
that the most striking colour-variations obtain. One form which is common among the coral- 
reefs on the Queensland coast-line, and much resembles the common British “ five-fingers” 
in size and shape, is brilliant ultramarine-blue. Another large pentagonal species, belonging to 
the group known as Cushion- 
stars, has a golden-brown 
ground, upon which are 
thickly scattered small bead- 
like tubercles of turquoise. 
A third form, not un- 
common on the Tasmanian 
coast-line, which is nearly 
related to the  Bird’s-foot 
species, previously mentioned, 
is distinguished by tints which 
range through several shades 
of crimson to brilliant violet. 
Not a few of the star- 
fishes are notable for their 
eminent phosphorescent 
properties. The group of 
the Snake-armed and Brittle- 
stars are more especially 
distinguished in this respect. 
Many of these species PRICKLY SEA-CUCUMBER
