Ichthyosaurus

Ichthyosaurus (meaning 'Fish Lizard') is a cathermal (active both night and day) prehistoric marine reptile from the Jurassic, added in the "Dinosaur Renaissance" 7.3.2 update. Adults are about 3 blocks long and about 1 block wide and are full grown at 7 days old. Newborns are about 1 block long and .5 blocks wide.

Like all mobs, Ichthyosaurus have a mood that ranges depending on several factors. If it is low, it will avoid or attack you. If it is high, they will remain calm and will not attack you. Ichtyosaurus will only attack on sight if its mood is on sad. Right-clicking with a Dinopedia will display the mood and other stats.

It drops Ichtyosaurus leg bone, eye, vertebrae, meat, foot, skull, rib cage, and arm bone upon death.

Like most of the mobs in this mod, they do not spawn naturally, and must be created by the player.

Behavior
Ichthyosaurus are aquatic, dolphin-like creatures (though they are not mammals) that can be created by the player. They do not break blocks weaker than iron. They are very fast swimmers, and are piscivores, meaning they eat fish. They are semi-passive, and only attack if hungry. They are hatched from a sac, and can be hatched either on land or water, though cannot move on land and must be put in water. Males have redder coloring on their body, and females have more green bodies.

Adult Ichthyosaurus breed every five minutes if there is a male and female present. The breeding probability is determined by how many individuals are near by.

Taming
Because it's hatched from a sac, it is tamed automatically after hatching. If hatched by use of a spawn egg, then it can be tamed by hand feeding or by using a whip. It can be ordered by an empty shell.

Feeding
Ichthyosaurus are piscivores, so they eat any kind of fish, including fish spawn, nautilus, Sio-Chiu-Le, and normal fish items (raw or cooked). They can also eat from a feeder with meat in it.
