Gadomus arcuatus (Family Bathygadidae) has a very long chin barbel for searching for food and long tactile rays in the pelvic and dorsal fins; these characters are often lost upon collection. This is a great example of how direct observations can provide new information on behavior and morphology, including live coloration.
