Meeting Abstract 23.7 Saturday, Jan. 4 14:45 The role of vertebral morphology in a fish eat fish world ACKERLY, KL*; WARD, AB; McGill University; Adelphi University kerri.ackerly@mail.mcgill.ca Many selective factors work together to determine the optimal body morphology to maximize swimming performance in fishes. The vertebral column is one of the most important morphological elements in determining […]
Symbionts are couch potatoes rounded bodies and loss of swimming in symbiotic “swimming” crabs
Meeting Abstract 23.2 Saturday, Jan. 4 13:45 Symbionts are couch potatoes: rounded bodies and loss of swimming in symbiotic “swimming” crabs. EVANS, N*; PAULAY, G; Univ. of Florida evansnat@ufl.edu Most members of the brachyuran family Portunidae swim with an efficiency unmatched by any other clade of crabs. This has been attributed to a number of morphological adaptations […]
Implications for the origin of baleen as revealed by palatal vascularization of a gray whale calf (Cetacea, Mysticeti)
Meeting Abstract 23.4 Saturday, Jan. 4 14:15 Implications for the origin of baleen as revealed by palatal vascularization of a gray whale calf (Cetacea, Mysticeti) EKDALE, E.G.; San Diego State Univ eekdale@projects.sdsu.edu The origin of baleen in Mysticeti was a major transition during cetacean evolution. All extant baleen whales are edentulous in adulthood, but teeth develop in […]
