Etymology: Castleichthys: Named for the late P.H.J. Castle, who located the specimen described here and recognized its novelty, but was unable to complete the description himself.. Also in recognition of his many contributions to our knowledge of eels and eel larvae.; auritus: Name from Latin 'auritus' meaning eared, refers to the large, conspicuous pectoral fins, which resemble the ears of a rabbit or a mule; an adjective.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00062 (0.00028 - 0.00136), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
