| Indentification
marks: Triggerfish can grow
as long as 70cm. Their body is flatterd at the side and
high; the sideview is a rhombus. The very big head runs
up conical; the eyes are put black widelyand very high;
the small mouth is provided with strong teeth. The first
back-fin is made of tree strong prickles, which get
smaller to the back and have a block-mechanism. The
second back-fin and the anus-fin are fin-sears. Way of Life: Triggerfish swim not only horizontally, but also diagonally or even in avertical position. The daily-active animals sleep in caves or holes at night and cling to surfaces with the help of their first back-fin-pricle. The second prickel is based on the first one and lies in a small hollow. Now it is impossible to fold the first prickle back. An enemy, which finds the Triggerfish in his cave, is unable to pull him out. Food: fish, crayfish, molluscs, corals, sea urchins and other kinds of echinoderm. |
