The Tennessee Aquarium maintains a mixed marine animal exhibit with
approximately seven (7) southern stingrays, (Dasyatis Americana). Feeding the animals in the
exhibit is the responsibility of the volunteer divers. Concern for the divers' welfare led us to
remove the venomous spines on a number of the stingrays. After anesthetizing the animals with
MS-222, the spines were excised with an Elman surgical cautery unit. Closure of the wound was
accomplished using Nexaband and 3/0 Vicryl absorbable suture. Little hemorrhage and no
complications occurred during the procedure. Postprocedural recovery was done in a holding tank
off exhibit for approximately five (5) days. Long term success of the procedure is mixed as some
animals are exhibiting barbule regrowth.
