“…The presence of deciduous cycloid scales was reported by Bolin (1933), Tortonese (1958), Walters & Fitch (1960), Palmer (1961), and Fitch (1964. Rosenblatt & Butler (1977) indicated that there were no scales present on their eight specimens of Zu.…”

“…Several authors list pelvic rays as 5-6, however, it is possible that the first short ray was overlooked due to its small size. Bolin (1933), however, describes the pelvic "spine" from two large (533 and 835 mm SL) specimens of Z. cristatus. The dorsal-fin rays of the nuchal pennant and those of the pelvic fin bear pigmented, membranous flaps that are serially arranged throughout the length of the rays (Fig.…”

“…Fitch (1961) suggested that Trachypterus semiophorus Bleeker 1868 from the Indo-Pacific and T. ijimae Jordan & Snyder 1901 from Japan are conspecific and belong to the genus Zu, but he did not synonymize them with Z. cristatus. Bolin (1933) had earlier described a juvenile (533 mm SL) and an adult specimen (835 mm SL) of T. ijimae (= Z. cristatus) collected off the California coast. Fitch & Schultz (1978) reported on a true adult specimen (980 mm SL) and acknowledged the radical difference between the juvenile and adult stages.…”

The family Trachipteridae—the Ribbonfishes, Dealfishes, and their relatives—has a circumglobal distribution, with at least 10 species in three genera (Zu Walters & Fitch 1960, Desmodema Walters & Fitch 1960, and Trachipterus Goüan 1770) that are characterized by elongate, extremely laterally compressed bodies, large eyes, absence of ribs, spines on lateral-line scales, greatly protrusible mouths, and a lack of pelvic fins in adults. They are also known for the drastic morphological changes that occur during ontogeny. Trachipterids are poorly represented in collections due to the fragile nature of their bodies. Most studies of the Trachipteridae have been limited by the numbers, developmental stages, and the completeness of the specimens that were examined. Along with the lack of available material, incomplete and conflicting character information compounds the taxonomic confusion of Trachipteridae. Despite the body of regional revisions that have examined trachipterid taxonomy, none have synthesized a suite of morphological characters across ontogeny. The goals of this paper are to (1) revise the family Trachipteridae, (2) revise the genera Trachipterus, Zu, and Desmodema, including information regarding ontogeny and biogeography, and 3) address the alpha taxonomy of Zu, Desmodema, and Trachipterus from the western Pacific Ocean. We recognize possibly five species of Trachipterus as being present in the western Pacific, as well as two species of both Zu and Desmodema. Despite additions to the specimen base that allows refinement of taxonomy and diagnoses, there are still large knowledge gaps associated with the taxonomic review of Trachipteridae. These reflect incomplete understanding of geographic distribution of taxa which may mask unrecognized taxonomic variability. The genus Trachipterus specifically remains problematic and will require greater detailed global study. Early life history stages remain unknown for several taxa which hinders full interpretation of ontogenetic transitions. Protracted transitions, some of which are clarified here, further confuse stage-based diagnoses and must be considered in future analyses of this family.

“…As confirmed by previous authors the anal fin is considered absent in this species, while the pelvic fins seem to be present only in the juvenile stage of the species, probably because in this phase all the fins are essential for swimming. Shifting to the adult stage, at an estimated size of 800 mm, these fins disappeared, and a small nubbin is usually found at pelvic fins insertion [20,81]. However, Palmer in 1961 untied this, like other characteristics of development, from just a concern of size, as influenced by the development of the single specimen [35].…”

Monitoring the occurrence and distribution of rare fish species is essential, especially in a semi-closed basin such as the Mediterranean Sea. Biologically interesting species often represent fishing waste (being part of the by-catch) and therefore are not retained, leading to a huge gap in data collection. Here we report about the occurrence in the Ionian Sea of a Zu cristatus (Bonelli, 1819) specimen, a mesopelagic fish from the order Lampriformes considered rare in the whole Mediterranean basin. The sample was captured at a depth of 720 m off the coast of Noto (Sicily, Italy) by deep-sea longline fisheries. The biometrics and meristic data were compared with all the available data on specimens previously reported in the Mediterranean Sea. It is interesting to note that, among the few records in the literature, most reports mention a lower depth range for this species. In fact, it is quite known that juvenile specimens of Z. cristatus were frequently found in shallow waters, while information about the biology of the adult stage is scarce, indicating they would seem to prefer much deeper environments. Considering the difficulty to collect data on this rare fish, this contribution can help to improve the knowledge about its distribution.

Connecting to Edward Flanders Ricketts through Mentors and an Iconic Ship Sailing in the Gulf of Alaska

This essay describes my connections to Edward Flanders Ricketts, fostered because I sailed on the ionic Western Flyer, the ship that Steinbeck and Ricketts chartered for their 1940 trip to the Sea of Cortez. I describe how I initially found out that the vessel was the same ship that I lived and worked on 1962–63 in Alaska. I then outline how my career as a marine researcher involved key mentors who were influenced by their communications with Ricketts or shared common ecological thinking. The Western Flyer is now being rebuilt as a vessel for marine education, and I speculate that Ricketts may have thought his spirit is perhaps imbued on the boat and could influence those who sail on her in the future.
