The preoral chambers of these zoeae are bordered on all sides, with the labrum and mandibles forming the anterior borders, the paragnaths and sternal projection together creating the posterior boundaries, and the maxillules forming the sides. The maxillules are the sole pair of appendages responsible for prey manipulation immediately preceding ingestion. Maxillules are capable of remarkable plasticity of movement, enabling them to grasp, control, and redirect violently struggling prey (Artemia sp. metanauplii). The asymmetrical mandibles tear and grind the prey, working against each other with rotating motions. Two separate ratchet-like coordinations of the appendages were seen, each of which enabled the zoea to maintain a firm grasp on the prey while renewing points of leverage for ingestion. The mandibles hold prey in position while the maxillules regrab it to push it farther into the mouth. Similarly, the labrum holds the prey while the mandibles prepare for a new grinding rotation. Capture and ingestion of an algal cell by a rapid outward flinging and inward clasping of the mouthparts was seen in one videotaped sequence. Gut fluorescence after introduction of various algal species reveals an ability to ingest a range of particle sizes. This plasticity of feeding behaviors allows the zoeae to ingest a range of food items, and thus meet their nutritional needs.</p>","PeriodicalId":153307,"journal":{"name":"The Biological bulletin","volume":" ","pages":"207-218"},"PeriodicalIF":1.6,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2307/1542616","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34802269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mummichogs are known to follow flooding tides onto the intertidal marsh to forage (1, 2). Through this behavior, they provide an important trophic link between salt marsh and open estuary (3). Previous research indicates that access to the intertidal flooded marsh has significant effects on the growth rate of F. heteroclitus. Weisberg and Lotrich (4) showed that foraging exclusively on subtidal food sources was not sufficient to support normal growth rates of mummichogs. Javonillo et al. (5) found that mummichogs denied access to the marsh had lower growth rates than those that were allowed entree to the marsh surface. Both of these studies employed caging techniques on a relatively small scale. Our goal was to examine the importance of marsh flooding to mummichog growth and abundance in a natural environment without enclosures. Tidal creek flooding onto the marsh determines the vegetation in the area surrounding the creek. Spartina altemijora grows on the marsh adjacent to the creek that floods on every high tide, whereas S. patens grows on the higher marsh that floods less frequently. We measured the length from the creek edge to the transition between S. altemijlora and S. patens at increments along the creek. The mean of these measurements multiplied by the length of the creek was considered the area of marsh accessible to mummichogs at high tides. This area is equivalent to the area of marsh adjacent to the creek covered by S. altemijora. A comparison of the regularly flooded area in the 5 tidal creeks that were part of our study is shown in Figure la. We measured the abundance and growth of F. heteroclitus in tidal salt marsh creeks of the Rowley River in the Plum Island Estuary in northeastern Massachusetts (42”44’ N X 70’50’ W).","PeriodicalId":153307,"journal":{"name":"The Biological bulletin","volume":" ","pages":"299-300"},"PeriodicalIF":1.6,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2307/1542663","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34802271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
