Updated: May 8, 2025

I would also mention quadrangular ostracions, having on the back four large tubercles; some dotted over with white spots on the lower part of the body, and which may be tamed like birds; trigons provided with spikes formed by the lengthening of their bony shell, and which, from their strange gruntings, are called "seapigs"; also dromedaries with large humps in the shape of a cone, whose flesh is very tough and leathery.
