Here, we investigate how glass catfish (\n                    <jats:italic>Kryptopterus vitreolus<\/jats:italic>\n                    ) modulate locomotor and group-level behavior across a gradient of oxygen saturation (95%\u201320%) while swimming steadily at a constant cruising speed. We found that tailbeat frequency decreased significantly with declining oxygen (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.0001), alongside reductions in wave speed (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.007). Tailbeat amplitude, by contrast, increased significantly under hypoxia (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.0001), and posterior segment angles showed a slight, non-significant increase, consistent with modestly greater tail bending. Despite these changes, the Strouhal number remained fairly constant, and waveform topology was conserved. School structure, including nearest-neighbor distance and distance to the center of the school, remained stable across oxygen treatments, but with significant variation across individual schools. A clear behavioral threshold was observed below 25% oxygen saturation, beyond which coordinated schooling deteriorated. These findings demonstrate that glass catfish employ internally coordinated, energetically economical kinematic adjustments to preserve group cohesion under metabolic constraint. This strategy highlights a decentralized mechanism for sustaining collective behavior near physiological limits and offers biologically-grounded insights relevant to energy-aware coordination in bioinspired swarms.\n                  <\/jats:p>","DOI":"10.1088\/1748-3190\/ae17fd","type":"journal-article","created":{"date-parts":[[2025,10,27]],"date-time":"2025-10-27T22:50:57Z","timestamp":1761605457000},"page":"066014","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Running on empty: locomotor compensation preserves fish schooling under hypoxia and informs principles for bioinspired swarms"],"prefix":"10.1088","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4614-9164","authenticated-orcid":false,"given":"Yuchen","family":"Gong","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0605-8195","authenticated-orcid":false,"given":"Robert","family":"Sterling","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6146-9668","authenticated-orcid":true,"given":"Xuewei","family":"Qi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0810-9783","authenticated-orcid":true,"given":"Fidji","family":"Berio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3515-6833","authenticated-orcid":true,"given":"Otar","family":"Akanyeti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5419-3747","authenticated-orcid":true,"given":"Valentina","family":"Di Santo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2025,11,6]]},"reference":[{"key":"bbae17fdbib1","doi-asserted-by":"publisher","first-page":"1395","DOI":"10.1111\/gcb.12754","type":"journal-article","article-title":"Climate change and dead zones","volume":"21","author":"Altieri","year":"2015","journal-title":"Glob.
