| ellipsomyxa syngnathi sp. n. (myxozoa, myxosporea) in the pipefish syngnathus typhle and s. rostellatus (teleostei, syngnathidae) from denmark. | a new species ellipsomyxa syngnathi sp. n. (myxozoa) is described from syngnathus typhle l. and syngnathus rostellatus nilsson, 1855 (syngnathidae), using spore morphology and ssu rdna sequence data. monosporic plasmodia develop in the internal gallbladder wall. the ellipsoid myxospore has two pyriform polar capsules which discharge at opposite sides some distance from both sutural line and spore ends. the myxospore mainly differs from that of ellipsomyxa gobii køie (folia parasitol 50:269-271, ... | 2009 | 19727823 |
| cranial architecture of tube-snouted gasterosteiformes (syngnathus rostellatus and hippocampus capensis). | the long snout of pipefishes and seahorses (syngnathidae, gasterosteiformes) is formed as an elongation of the ethmoid region. this is in contrast to many other teleosts with elongate snouts (e.g., butterflyfishes) in which the snout is formed as an extension of the jaws. syngnathid fishes perform very fast suction feeding, accomplished by powerful neurocranial elevation and hyoid retraction. clearly, suction through a long and narrow tube and its hydrodynamic implications can be expected to req ... | 2010 | 19798732 |
