A new species of Elassodiscus (Cottoidei: Liparidae) from the North Pacific with an emended diagnosis of the genus

This paper is a checklist of the fishes that have been documented, through both published and unpublished sources, in marine and estuarine waters, and out 200 miles, from the United States-Canadian border on the Beaufort Sea to Cabo San Lucas, Mexico. A minimum of 241 families and 1,644 species are known within this range, including both native and nonnative species. For each of these species, we include maximum size, geographic and depth ranges, whether it is native or nonnative, as well as a brief mention of any taxonomic issues.

“…Nakazawa (1915) reported that putative Cyclopteridae (or Liparidae) species eggs were laid in the gill cavity of Paralithodes camtschaticus. In addition, Somerton and Donaldson (1998) report on the deposition of egg masses by Careproctus furcellus and Elassodiscus nyctereutes, the authors call this species "red snailfish" in the original article and Kai et al (2021) described it later, into the gill cavity of golden king crabs, Lithodes aequispinus; although Somerton and Donaldson (1998) mentioned this body cavity as "branchial chambers", it may indicate the same part of "gill cavity". Poltev and Mukhametov (2009) found egg masses deposited in the gill cavities of 9.9% of golden king crabs captured at depths of 209-716 m. Subsequently, Gardner et al (2016) showed that eggs deposited in Lithodes aequispinus and Lithodes couesi, were from Careproctus melanurus, C. colletti, C. furcellus, and C. simus, on the basis of mitochondrial DNA sequences.…”

The reproductive biology of deep-sea fishes is largely unknown because of the difficulty of behavioral observations in this environment. In this study, the reproductive behavior of the deep-sea snailfish, Careproctus pellucidus, which lives at depths > 200 m, was observed in an aquarium. Fishes were collected at a depth of approximately 300 m in the North Pacific Ocean (36°70′N; 141°00′E) in July and August 2018 and kept for observation until March 2019. We observed that spawning events usually took place between one male and one female. Males defended a spawning substrate against other males and exhibited body-wiggling behavior for both courtship and aggressive display. Females visited the male's territory and spawned a demersal adhesive egg mass on the substrate. The territorial male then sought the spawned eggs using the filamentous rays in the lower pectoral-fin lobe and released sperm when he located the eggs. Males remained near the spawning substrate after spawning but did not perform any parental care. Notably, sneaking behavior by a non-territorial male was observed in one case; this is the first report of this alternative reproductive strategy (or tactic) in a deep-sea fish. Our study reveals the spawning of C. pellucidus appear to use the mechanosensory lateral line and the chemical sense heavily to adapt to the dim sunlight deep-sea environment.
