This is the giant amphibian Hynerpeton; the prototype land-dweller for the next 300 million years.

Walking with Monsters: Water Dwellers

Hynerpeton was a large, primtive amphibian from the Devonian. It was one of the first vertebrates to come onto land.

Physical appearance and biologyEdit

Hynerpeton had a long and streamlined body fitted with an eel-like tail. It had four legs with eight digits per foot. It also had jaws fitted with needle-sharp teeth. It was black with yellow strips and splodges.

Behaviour and traitsEdit

Hynerpeton was an animal suited to the water rather than land. In the water, it was an able, fast swimmer. On land however, it was cumbersome and slow and needed to reside close to water as its lungs were not as good as inhaling oxygen. Being near to water meant that oxygen from the water could enter its body via its skin. Despite its limitations, land was a far more safer place as the landscape back in the Devonian was drastically underpopulated. Due to this, Hynerpeton could go onto land without fearing predation.

The mating seasons of Hynerpeton were brief and mainly took place during the night. During this time, males would try to mate with as many females as possible. In the case of competition, males would perform a press-up motion and would snap their jaws repeatedly until one of them backed down.

In Walking with MonstersEdit

Water DwellersEdit

A male Hynerpeton came out of the water to bask with several other individuals. The same male approached a small scorpion and ate it before re-entering the water. Whilst swimming, a Stethacanthus pursued the male. Fortunately for the Hynerpeton, the shark was eaten by a massive Hyneria. However, once it devoured its meal, the fish turned its attention to the amphibian. Luckily, the Hynerpeton managed to escape the Hyneria.

Coincidentally, at the moment where the male Hynerpeton returned to the land, many females appeared from the water, marking the brief mating season. During the night, a rival male appeared on the scene and challenged our male for the right to mate. However, after a mating dance and different means of intimidation, the challenger backed down.

In the morning, the male Hynerpeton calls for a female. A female responded and came onto land to mate, whilst laying her eggs. As they mate, a large Hyneria attacked them but fortunately for the amphibians, they narrowly avoided the fish. However, the Hyneria dragged itself onto the shore and caught the male Hynerpeton by surprise. The fish then killed its victim. Subsequently, the Hynerpeton eggs evolved into Petrolacosaurus eggs.
