I'll also mention some quadrangular trunkfish topped by four large protuberances along the back; trunkfish sprinkled with white spots on the underside of the body, which make good house pets like certain birds; boxfish armed with stings formed by extensions of their bony crusts, and whose odd grunting has earned them the nickname "sea pigs"; then some trunkfish known as dromedaries, with tough, leathery flesh and big conical humps.
A háromszögletes páncélúak közül láttam öt centiméter hosszú halakat, ezeknek kitűnő az íze; ajánlatos volna őket édesvízben is meghonosítani, aminek nincsen semmi akadálya, mert egyes tengeri halak könnyen hozzászoknak az édesvízhez.
