The Water World on Shalimar

The warm oceans of Shalimar support a number of biomes with interesting life forms. So far our survey team has explored these

In all these environments we see about ten percent of the weight of the organisms on each step being passed up to the next step of the food chain:

1000 pounds of plant material support
100 pounds of small herbivores support
10 pounds of small carnivores support
1 pound of top predator

Therefore we see many, many small organisms and few large ones.

The life forms in the water are all cold blooded: that is, they do not use energy to heat their bodies.
