Could my leviathans exist?

Leviathans are closely related to hydrophis spiralis. Some characteristics of these leviathans include:

• continuing to grow until they die and are able to grow almost as large as a blue whale
• are warm blooded similar to mosasaurs, birds, and mammals (optional)
• experience negligible senescence
• scales are made of the same material as Limpets teeth
• are carnivorous
• rarely breed
• give live birth similar to mosasaurs
• can spit out a burning spray similar to a bombardier beetle

Given these characteristics, could such a creature realistically exist and what evolutionary pressures would lead to them?

NOTE: magic does not exist in my story
