Cranial Architecture of Tube - snouted

21 The long snout of pipefishes and seahorses (Syngnathidae, Gasterosteiformes) is formed as an 22 elongation of the ethmoid region. This is in contrast to many other teleosts with elongate 23 snouts (e.g. Butterflyfishes) in which the snout is formed as an extension of the jaws. 24 Syngnathid fishes perform very fast suction feeding, accomplished by powerful neurocranial 25 elevation and hyoid...

Mechanical properties of the dorsal fin muscle of seahorse (Hippocampus) and pipefish (Syngnathus).

The dorsal and pectoral fins are the primary locomotor organs in seahorses (Hippocampus) and pipefish (Syngnathus). The small dorsal fins beat at high oscillatory frequencies against the viscous medium of water. Both species are able to oscillate their fins at frequencies likely exceeding the point of flicker fusion for their predators, thus enhancing their ability to remain cryptic. High-speed...

Anthropoid cranial base architecture and scaling relationships.

This paper examines how various measures of basicranial length and cranial base angulation affect the relationship between basicranial flexion and relative brain size in anthropoids, including Homo sapiens. Most recent studies support the "spatial packing" hypothesis, that basicranial flexion in haplorhines maximizes braincase volume relative to basicranial length. However, a few studies find t...

The relationship between female body size and egg size in pipefishes.

Comparing five species of pipefish, egg size was significantly larger in species with brood pouches (Syngnathus typhle, Syngnathus acus and Syngnathus rostellatus) than in species without brood pouches (Entelurus aequoreus and Nerophis ophidion). Egg size correlated positively with female body size in species with brood pouches, but was similar across female sizes in the species lacking pouches...
