HALF AN HOUR WITH SEA-ANEMONES.

are they all!" The "Orange-Disked Anemone" 

 (Sagartia venusta) is found in various places along 

 the south and west coasts of Great Britain and 

 Ireland, and is remarkable for its bright orange 

 disk and snow-white tentacles. It is usually found 

 in colonies, thus differing from the "Cave Anemone." 

 Specimens may sometimes be obtained an inch and 

 a half in diameter when the tentacles are expanded. 

 This species is perhaps the most lovely of all our 

 native sea-anemones, and 

 when seen in its healthy con- 

 dition, the most matter-of- 

 fact philosopher might be 

 tempted to pardon the enthu- 

 siastic admiration of anemone 

 collectors for it. The " Para- 

 sitic Anemone " (Sagartia 

 parasitica, Fig. 66) is often 

 found in large numbers where 

 it does occur. It takes its 

 name from its habit of at- 

 taching itself to some shell, 

 generally to that of the common cockle, as shown 

 in Fig. 66. It is also found on dead shells, 

 especially on those inhabited by the Hermit-crab, 

 and in this respect much resembles the Adamsia. 

 It is a species which thrives very well in the 

 aquarium, where it will leave the shell, and attach 

 itself to the glass. One good distinguishing mark 

 of this species, besides its parasitic habit and striped 



Parasitic Anemone 

 (Sagartia parasitica).
