Transverse sections of the skin in the dorsal fin of the white shark, Carcharodon carcharias, tiger shark, Galeocerdo cuvier, and spotted raggedtooth shark, Carcharias taurus, show large numbers of dermal fiber bundles, which extend from the body into the fin. [...] Key Result The bundles are tightly grouped together in staggered formation (not arranged in a straight line or in rows). This arrangement of dermal fibers gives tensile strength without impeding fiber movement.Expand
Caudal fin in the white shark, Carcharodon carcharias (Lamnidae): A dynamic propeller for fast, efficient swimming
TLDR
Overall, the anatomy and mechanics of the dorsal lobe of C. carcharias facilitate greater control of movement compared to the ventral lobe, and provides considerable potential for an elastic mechanism in the animal's swimming motions and consequently for energy conservation. Expand
Anatomy and muscle activity of the dorsal fins in bamboo sharks and spiny dogfish during turning maneuvers
TLDR
The function of the dorsal fins during turning maneuvering in two shark species with different swimming modes is investigated here using musculoskeletal anatomy and muscle function to find dogfish sharks passively stiffen the dorsal fin structurally and functionally, while bamboo sharks have more flexible dorsal fins, which result from a steady swimming trade off.

Taphonomic evidence for high-speed adapted fins in thunniform ichthyosaurs
TLDR
It is the first mechanostructural study of the control surfaces of a Jurassic ichthyosaur that adds essential evidence in support of the view that these forms were high-speed thunniform swimmers. Expand
Caudal fin allometry in the white shark Carcharodon carcharias: implications for locomotory performance and ecology
TLDR
It is suggested that buoyancy may play a dominant role in larger white sharks in permitting slow swimming while minimizing energy demands needed to prevent sinking, in contrast hydrodynamic lift is considered more important in smaller white sharks. Expand
Convergence in Thunniform Anatomy in Lamnid Sharks and Jurassic Ichthyosaurs.
TLDR
Among extinct ichthyosaurs the Jurassic forms Ichthyosaurus and Stenopterygius share a number of anatomical specializations with lamnid sharks that allow their inclusion within the mode of high-speed thunniform swimming to which only two other equally distinctive phylogenetic groups belong, tuna and dolphins-a striking testaments to evolutionary convergence.

The functional role of caudal and anal/dorsal fins during the C-start of a bluegill sunfish

TLDR
It is suggested that the active control of the anal/dorsal fins can be related to retaining the stability of the sunfish against roll and pitch movements during the C-start. Expand
Scale morphology and flexibility in the shortfin mako Isurus oxyrinchus and the blacktip shark Carcharhinus limbatus
TLDR
Manual manipulation of the scales at 16 regions on the body and fins revealed a range of scale flexibility, from regions of nonerectable scales such as on the leading edge of the fins to highly erectable scales along the flank of the shortfin mako shark body. Expand
A new Chinese specimen indicates that ‘protofeathers’ in the Early Cretaceous theropod dinosaur Sinosauropteryx are degraded collagen fibres
TLDR
A new specimen of Sinosauropteryx is reported which shows that the integumental structures proposed as protofeathers are the remains of structural fibres that provide toughness. Expand
A unique cross section through the skin of the dinosaur Psittacosaurus from China showing a complex fibre architecture

  • Proceedings of the Royal Society B: Biological Sciences
  • 2008
TLDR
This paper reports on a unique preservation of soft tissues in the ventrolateral region of the plant-eating dinosaur Psittacosaurus from the Jehol biota of China, which includes multiple layers of collagenous fibres in excess of 25, among the highest recorded in vertebrates. Expand
New findings reveal that the middle Triassic ichthyosaur Mixosaurus cornalianus is the oldest amniote with a dorsal fin.
Two excellently preserved specimens of Mixosaurus cornalianus from the Anisian layers of the Middle Triassic Formazione di Besano, with soft parts associated with well-articulated skeletal elements,Expand

THE MECHANICS OF FISH SKIN: LACK OF AN "EXTERNAL TENDON" ROLE IN TWO TELEOSTS
TLDR
Biaxial stressing tests demonstrate that the skins of the spot and the skipjack do not behave as simple crossed-fiber systems, and are therefore incapable of transmitting forces down the lengths of these fishes or acting as "extensible" systems. Expand
Locomotor function of the dorsal fin in teleost fishes: experimental analysis of wake forces in sunfish.
TLDR
Empirical evidence is presented that vortex structures generated by the soft dorsal fin upstream can constructively interact with those produced by the caudal fin downstream, and Reinforcement of circulation around the tail through interception of the dorsal fin's vortices is proposed as a mechanism for augmenting wake energy and enhancing thrust.

The mechanical implications of different tooth designs are scanned, hypotheses that relate to primary considerations of the physics of cutting compliant substrates are posed, and a preliminary approach is offered that is intended as a useful guide to further studies on sharks and on other vertebrate groups.

The locomotor mechanism of sharks is adapted for an efficient cruising swimming but at the same time, the potential instability in the sagittal plan allows for the production of turning moments that are used in attack and feeding. Expand

Size of the Great White Shark (Carcharodon)
TLDR
The maximum length of 36.5 feet (11.1 meters) attributed to the white shark (Carcharodon carcharias) by G�nther and others is a mistake and comparison with the jaws of white sharks of known length revealed a length of about 17 feet (∼5 meters). Expand

TLDR
The white shark may be the chief marine predator of adult chelonians in the Mediterranean Sea, albeit the impact of this predation upon turtle populations is nominal compared to other sources of mortality. Expand
