Figure 1.--Attempts to hold sea otters in this tank in 1954 were unsuc- 
cessful. An insufficient flow of water allowed food scraps and fecal 
matter to accumulate, causing fur to lose waterproof qualities. Also, 
insufficient space was provided for otters to get out of the water. 
Otters survived in this environment only a few hours. (KWK 59-9-6)

Figure 2.--Otters held on dry litter habitually lay on their backs while 
eating, allowing food slime and scraps to soil their fur. When again 
permitted to enter water they became soaked to the skin and suffered 
severe chilling. Animals shown here, when liberated at the Pribilofs 
in 1955, soon succumbed to exposure. (KWK 55-5-1)
