To increase power production for expansion, many species employ in-series tendons and catch mechanisms to store and release elastic strain energy. Suction feeding sharks such as Chiloscyllium plagiosum lack large in-series tendons on the hypobranchials, yet two of the hypobranchials, the coracohyoideus and coracoarcualis (CH, CA; hyoid depressors), are arranged in-series, and run deep and parallel to a third muscle, the coracomandibularis (CM, jaw depressor). The arrangement of the CH and CA suggests that C. plagiosum is using the CH muscle rather than a tendon to store and release elastic strain energy. Here we describe the anatomy of the feeding apparatus, and present data on hyoid and jaw kinematics and fascicle shortening in the CM, CH and CA quantified using sonomicrometry, with muscle activity and buccal pressure recorded simultaneously. Results from prey capture show that prior to jaw and hyoid depression the CH is actively lengthened by shortening of the in-series CA. The active lengthening of the CH and preactivation of the CH and CA suggest that the CH is functioning to store and release elastic energy during prey capture. Catch mechanisms are proposed involving a dynamic moment arm and four-bar linkage between the hyoidiomandibular ligament (LHML), jaws and ceratohyals that is influenced by the CM. Furthermore, the LHML may be temporarily disengaged during behaviors such as bite processing to release linkage constraints.<\/jats:p>","DOI":"10.1242\/jeb.165290","type":"journal-article","created":{"date-parts":[[2017,8,15]],"date-time":"2017-08-15T00:10:30Z","timestamp":1502755830000},"source":"Crossref","is-referenced-by-count":5,"title":["Function of the hypobranchial muscles and hyoidiomandibular ligament during suction capture and bite processing in white-spotted bamboo sharks, <i>Chiloscyllium plagiosum<\/i>"],"prefix":"10.1242","author":[{"given":"Jason B.","family":"Ramsay","sequence":"first","affiliation":[{"name":"Biological Department, Westfield State University, 577 Western Avenue, Westfield, MA 01086, USA"},{"name":"Department of Biological Sciences, College of the Environmental and Life Sciences, University of Rhode Island, 120 Flagg Road, Kingston, RI 02881-0816, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheryl D.","family":"Wilga","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, College of Arts and Sciences, University of Alaska Anchorage, 3211 Providence Drive, CPSB 101 Anchorage, AK 99508, USA"},{"name":"Department of Biological Sciences, College of the Environmental and Life Sciences, University of Rhode Island, 120 Flagg Road, Kingston, RI 02881-0816, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"237","published-online":{"date-parts":[[2017,1,1]]},"reference":[{"key":"2021042523155017300_JEB165290C1","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1002\/jmor.1051940108","article-title":"Model of jaw depression during feeding in Astatotilapia elegans (Teleostei: Cichlidae): mechanism for energy storage and triggering","volume":"194","author":"Aerts","year":"1987","journal-title":"J.
