in a parasitic study on five sharks (carcharhinus macloti) caught from the iranian coasts of persian gulf, two of five sharks appeared to have nematode in their intestine. using light microscopy, the nematode was identified as acanthocheilus rotundatus. a. rotundatus  is characterised by 3.3-4.5 cm in length, semithick cuticle, small lips, semicircular and tri-lobed pseudolabia (not offset from...

Two new Vertomannus species, Vertomannus flavus sp. n. (south Vietnam) and Vertomannus borneensis sp. n. (Borneo) are described. Vertomannus (Elongatomannus), subgen. n. (type species: Vertomannus flavus) is proposed.

Longevity of Rhizoprionodon terraenovae and Carcharhinus acronotus in the western North Atlantic Ocean was examined using direct age estimates from vertebral sections and tag-recapture data. Time-at-liberty ranged from 7.7-14.0 years (mean =10.1) for R. terraenovae and 10.9-12.8 years (mean =11.9) for C. acronotus. Maximum estimated longevity was determined to be 19.8 years through tag-recaptur...

A simple metric (span condition analysis; SCA) is presented for quantifying the condition of sharks based on four measurements of body girth relative to body length. Data on 104 live sharks from four species that vary in body form, behaviour and habitat use (Carcharhinus leucas, Carcharhinus limbatus, Ginglymostoma cirratum and Galeocerdo cuvier) are given. Condition shows similar levels of var...

the systematics, morphology, distribution, biology, economic importance and conservation of the bull shark ( carcharhinus leucas ) in iran are described, the species is illustrated, and a bibliography on this fish in iran is provided.

Diving with sharks, often in combination with food baiting/provisioning, has become an important product of today's recreational dive industry. Whereas the effects baiting/provisioning has on the behaviour and abundance of individual shark species are starting to become known, there is an almost complete lack of equivalent data from multi-species shark diving sites. In this study, changes in sp...
