Vertical range. — Acanthephyra dehilis is a free swimming 

 species ; it has been trawled in soundings varying from 411 to 

 2,512 fathoms, but there is no evidence to prove that the 

 species ever lives actually on the bottom. On a few occasions 

 adults and larvae have been caught quite near the surface 

 (S.R. 337 and S.R. 503).
