Achmachelus

## Achmachelus subitamortis

Timespan: Tyrannidean to Gnathian Stages of the Atroxian (R.19 - R.43)

Habitat: Deep Ocean, Continental Slope (Mid Ocean)

Distribution: Under Temperate and Tropical Uteenessa Ocean

Niche: Benthic Filter-Feeder

Size: 6.5cm

Predecessor: Makryostus wavii

Classification: Makryostusidae, Spinacheliforme, Caudara

Info: Two dangerous spikes, which continue in their ancestors in the modern day, made this animal difficult to attack. It prospered in its time and gave rise to a couple of important lineages.

Description: It had a tapering body, lined with electroreceptor and three gills on each side. On the tail end, it has two venomous spikes with vasodentrin barbs. An open circulatory system bathed the organs in hemacoel, and the body was controlled by ganglia. Down the back are cartilage vertebrae. In the gut, was a primitive stomach with the ability to digest multicellular matter.

## Achmachelus occisorum

Timespan: Tyrannidean to Gnathian Stages of the Atroxian (R.22 - R.41)

Habitat: Deep Ocean, Continental Slope (Mid Ocean)

Distribution: Under Temperate and Tropical Ocean

Niche: Apex Predator

Size: 6.5cm

Predecessor: Achmachelus subitamortis

Classification: Makryostusidae, Spinacheliforme, Caudara

Info: The first chordate predator had arrived; it was comparatively large and wielded deadly spines on its tail. When it found another animal it would swingits tail into them, delivering a deadly toxin. It then followed its wounded prey until it became motionless, and then started to feed on the body like a hagfish would. It has no jaw, so it could not grip, but it instead it would get a purchase with its teeth and then used its flexible body to pull a chunk off.

Description: It had a tapering body, lined with electroreceptor and three gills on each side. It has a pair of cup eyes on its head and it's circular mouth is full of small teeth. On the tail end, it has two venomous spikes with vasodentrin barbs. An open circulatory system bathed the organs in hemacoel, and the body was controlled by ganglia. Down the back are cartilage vertebrae. In the gut, was a primitive stomach with the ability to digest multicellular matter.

## Achmachelus acinus

Timespan: Gnathian Stage of the Atroxian (R.41)

Habitat: Deep Ocean, Continental Slope (Mid Ocean)

Distribution: Under Temperate and Tropical Ocean

Niche: Minor Predator

Size: 10cm

Predecessor: Achmachelus subitamortis

Classification: Makryostusidae, Spinacheliforme, Caudara

Info: A genetic deformity caused the significant loss of neurones in this short-lived offshoot. It did not last long before it went extinct.

Description: It had a tapering body, lined with electroreceptor and three gills on each side. At the front, it has a cartilage jaw. On the tail end, it has two venomous spikes with vasodentrin barbs. An open circulatory system bathed the organs in hemacoel, and the body was controlled by a very small amount of ganglia. Down the back are cartilage vertebrae. In the gut, was a primitive stomach with the ability to digest multicellular matter.
