How does the ichthyosaur detect its prey?
If the player swims out too far from the land, an Ichthyosaur can be heard and a few seconds after the player dies, while the creature cannot be seen. Interestingly, the Ichthyosaur sounds are named “ping1.wav” and “ping2.wav.” This could suggest that the Ichthyosaur detects its prey in a manner similar to sonar.
How do you get the ichthyosaur out of the water?
It is possible to lure the Ichthyosaur out of the water in Half Life, specifically at the Dam section.

If the Ichthyosaur is killed in Half-Life (GoldSrc version), the player can stand on its body as the body is solid.
How dangerous are ichthyosaurs?
