On upper page there are some "whales" from Ullr equatorial sea. All these creatures breath air and had land ancestors. Biggest of them are about 7 meter long (Ullr is mostly frozen planet, so in its small equatorial sea there is no place for true giants).
The one with filterfeeding basked formed by its four tongues is more primitive alien (Ull "reptile") with only one pair of limbs, it is propeled by waving its abdomen like shark. Other ones are quadrupedal (Ullr "mammals"). They use more diversified methods of swimming.
The big one with long jaws and blue sides (I wanted to name it Taurocetus) transformed its hind legs into tail fluke and swims like whale. Its giant eyes enable it to see in dark deep waters, where it hunts.
There is also manate-like herbivore, which swims using its four long fins like oars (or like plesiosaurs on earth) and small, agile "fish" hunter, which looks similar to Earth sharks, hovever it had land ancestors (with body shape a little similar to lizards).
On lower page there is Monstroastacus. Biggest askewbug species, which can be over 2 meter long (not counting antennas). It lives deep in sea (hovever can migrate closer to surface during the night) and its probably Ullrian equivalent of giant squid.
