背面の脊椎 (合計) : 6 - 7; 背鰭 (合計) : 10; 臀鰭: 9. Distinguished by having the following characteristics: thin and elongate in form; reduced scale cover and head pores; depth of body about 2 mm (Ref. 92840); uniformly dark on dorsal third of body and pale on remainder; clear median and paired fins; frenum connecting the upper lip to snout is reduced; separated upper lip and snout; tongue is emarginate (Ref. 44822).
Obligate sponge dwellers. Live deep within canals of the sponges, near the openings to the incurrent canals. Sponges provide species with protection from predators and an available food source in many invertebrates. Eggs found within sponge or small plankton brought through incurrent pores (Ref. 92840).
