Okay, I'm gonna use my last WIP, because it's worth a shot, right?
WIP
Thermpyre
Combination of "Thermal" + "Pyre", and also "Vampire"
Pronounced as "thurm-payh-uhr"
Thermal, to represent the most obvious example of heat in the ocean, hydrothermal vents, and pyre, to represent a pile of burning wood (which could be for the purpose of burning a dead body), as well as to connect it to the Vampire squid's scientific name. Together, the name also sounds similar to Vampire, again tying it to the Vampire Squid.
Comments would be greatly appreciated, I'm currently stuck between this name and Boilopod.
