SEA-SHORE LIFE 



Balanus hamei'i, Fig. 49^, is a large rough-looking, solitary 

 barnacle that grows upon rocks below low-tide level off the coast 



of New England north of Cape 

 Cod. 



The Whale Barnacle, fCoro- 

 nida diadevia, Fig. 50 J, is at- 

 tached to the skin of whales, 

 the skin being drawn up into 

 the shell of the barnacle so as 

 to enable it to adhere firmly. 

 The shell of this barnacle is fully 

 an inch and a half wide and an 

 inch high. In cross section it 

 is hexagonal with six longitudi- 

 nal ribs, each made up of four 

 F,-g. 3o; WHALE BARNACLE. ^^. ^^^^ ridges. In bamacles that 



groAv upon moving animals, the feathery feet are merely thrast out, 

 and not waved about as in the rock barnacles, which must create 

 currents in order to 

 capture their food. 



The Stalked Bar- 

 nacles, (Fig. 51). These 

 are often called "goose 

 barnacles," for the 

 naturalists of the sev- 

 enteenth century be- 

 lieved that geese 

 hatched from them. 

 They are usually found 

 attached to floating 

 objects, such as the 

 gulf weed, drifting 

 logs, pumice or buoys. 



The fleshy stalk 

 by which the barnacle 

 is attached is the head 

 end of the creature, 

 and the feathery, curling legs are seen to protrude now and again 

 through a cleft in the side of the shell. There is a minute eye
