The Sliquifer is a dragon from the Dragons: Rise of Berk and the School of Dragons video games based on the Dreamworks How to Train Your Dragon franchaise. It is also briefly seen in the film How to Train Your Dragon 2. They are Tidal Class dragons which can spit acid, and can swim at incredible speeds. Their acidic venom is weak, only causing a rash, but combined with the speed the creature moves at the acid hits the prey at high velocity, packing a punch!
They have glowing eggs and glowing acid. The regular sliquifers are sea green and purple, but they have a yellow and cyan coloured 'Titan Wing' form, with glowing tendrils.
