Traps did not do so well this morning & held but a couple of shrews.
A 52 ft Finback whale was brought in last night & at 8:30 this morning the large tail muscles & viscera were still steaming with animal heat.
This animal had been feeding on shrimp-like crustaceans about half an inch in length & its stomach contained
about 2 barrels of them.
We counted the baleen plates & found 328 rows on one side of the mouth. These strainer plates only occur on the upper
side of its mouth and in this whale extended about 7 ½ feet along the outer edge on lips. These plates were very
short near the front end of the mouth & at the back were about 15 inches in length – being larger towards the outside
& shorter towards the place where the tongue should be. The tongue in this species is very rudimentary and indicates
that the food is obtained by opening the mouth wide, taking in a large school of small fish or shrimp at the same
time, extending the gular pouch. Closing the mouth the gular region is contracted & the food strained from the water
by the baleen plates. This operation does not necessarily have to be close to the surface.
