The Crayfish Invertebrates 
CARE 
The great point in keeping crayfish alive in an 
aquarium is to give them a chance to breathe. 
Having plant life in the water will help, but even 
with this the aquarium must be arranged so that the 
crayfish may reach the surface of the water, and thus 
supplement the oxygen which it gets from the water. 
THE CRAYFISH 
Oh, Mr. Crayfish, you are, you know, 
The color of the brook, 
And I can never see you go, 
Unless I “‘speshul” look. 
You have so many legs 
And fringing swimmerets, 
That I should think you’d never know 
Which pair forward sets. 
Your big front fists in padded gloves 
Give you a boxer’s fame, 
But you do not strike, you always pinch; 
Like a girl you play the game.
