The seas of Skatha are home to an abundant amount of life, large and small, docile and dangerous. These are some drawings of a few species of larger vertebrates. We'll start with the hunters:
These are large cetacean like animals that are the predominantly open ocean hunters, with the exception of a few of the smaller individuals who also hunt in shallow seas near land. They are all site based hunters and though they often patrol areas of deep waters they stay close to the sunlight where they can more easily see their prey. The larger animals (the largest grey and smaller dark grey one) will often prey on smaller "cousins" if they happen to share a similar range.
The range of the hunters almost always overlaps with the wide range of the large filter feeders:
The filter feeders have a very large range and will often cross paths. However they rarely have competition as they generally feed on different food sources. These animals are larger than most the hunters pictured above, and don't need to worry about predation once they are adults, however there are other threats to them that come from other species (I will get into this later).
Another animal is a type of "gulp feeder," which swallows its prey whole in a, well, gulping fashion. It is a relative of the filter feeders seen above.
