Some More Things Recently Confirmed In The Hunter's Encyclopedia 4(Note: Some of this is for the 3rd Gen.)
 * Male Barroth have a larger crown than female Barroth. During the Breeding Season, male Barroth will allow multiple female Barroth to live and stay in their bogs before mating with them. Male Barroth fight each other for muddy bogs in order to survive the deadly Dry Season plus to take over a bog occupied by a large number of females. Barroth also use the mud to protect themselves from parasites.
 * Young Tetsucabra are shown in the book. They are described to have a fin-like tail instead of a spiky tail. Though other amphibian-like creatures are seen in the book as well.
