Enirams look a bit like this
Eniram
The Eniram Empirium.
The Eniram are a species that live mostly underwater. They are normally hostile but are probably just misunderstood. An average Eniram is the same height as a human, has two webbed feet and two webbed hands, and looks a bit like the creature from the black lagoon. The creatures are covered head to tow in scales and are green and clammy in appearance. They can exist out of water and walk on land, but normally prefer to swim about in the ocean.
The Eniram were first encountered when the Blue Dwarf crashed into the ocean on their world in July 2101. The Eniram took the Blue Dwarf and it's crew for their enemy the Aeron, and invaded the ship.
This planet was wiped out and all Eniram killed just after the Blue Dwarf left, by the Aerons and Eniram firing massively destructive missiles at each other.
Weapons.
Eniram have been known to carry a sharp and dangerous-looking harpoon gun, as it works effectively on land as well as underwater.
Craft
The Eniram have never been found to be capable of space-flight, although their existence on many worlds proves that they must have the capability. Eniram have powerful submarines, some shaped like vicious fish.
Truce
In 2105, the Eniram made a truce with their long-time enemies the Aerons to work together against the Hymenoptera.
