Their name is derived from the Greek psychrolouteo, meaning "to have a cold bath". They tend to live in colder waters, although some range into warm-temperate seas. The blob sculpin, Psychrolutes phrictus, exhibits complex nesting behaviors complete with egg guarding. Reproductively the blobfish have been seen gathering in large numbers to lay their pinkish eggs in a single surrounding nesting area. The number of eggs laid within one nest can range from 9,000 to 108,000. Another observation of the parental care of the blobfish is that their eggs resemble being cleaned. It is believed that as the female blobfish hover around the nests they also clean them and remove any sand or dirt. References Glubokov, A.I., Glubokovskii, M.K. & Kovacheva, N.P.
