Hengrauggi

The snow slug was a species of animal native to Delta Vega. Despite their name snow slugs had more in common with more complex invertebrates; featuring six limbs, the two front most with claw-like hands, and a mouth that separated into several segments to shoot out two long squid-like tentacles. They also had two tails. The majority of the snow slug population were a little larger than an average humanoid, though at least one member of the species was observed to grow many times larger.

In 2265 snow slugs and polarillas had overrun the Starfleet outpost on Delta Vega. Special agent Erin Esurance was sent by Starfleet Command to investigate when contact was lost with the outpost. Upon beaming down to the planet Esurance had to battle her way past numerous snow slugs to make it into the base, and then past more of them within the base. When she eventually located fellow Starfleet officer Keenser in the base a particularly large snow slug burst through the wall of the room they were in an attacked. However Esurance was able to use her phaser to neutralise the animal.
