In actuality, in Calcutta on 9 January 1979,
in the discourse "The Great Exceptions", the name Baba has told for the ancient ancestor of fish is "Coelacanth"; this name comes from the Latin Cœlacanthus meaning "hollow spine". The Coelacanth fish still exists today along the coastlines of the Indian Ocean and Indonesia, and is believed by scientists to have evolved into its current form 400 million years ago. (1) There is no fish named Silákantha, but our Tiljala Publishers never bothered to find this out. Rather they would have us believe that this most ancient of fish has a Bengali name.
So TP has concocted the name Silákantha. But the correct name is Coelacanth. All Margiis should please locate their Ananda Vacanamrtam part 8, and correct the passage.
Here below is a photo of this ancient Coelacanth fish:
