First Report on Recruits of Bigeye Thresher Shark Alopias Superciliosus (Laminiformes: Alopidae) with Largest Birth Size from Indian Waters
Four embryonic bigeye thresher sharks Alopias superciliosus (126–158 cm total length) were collected from two females caught by bottom set gillnet and hook and line (operating in 120–800 m depth) caught from off Kanyakumari area and landed in Cochin Fisheries Harbour on 11-06-2012 . Detailed morphometric measurements are provided. The ratio of size at birth (Lb) and maximum observed length (L m...
متن کاملMovement patterns and nursery habitat of juvenile thresher sharks Alopias vulpinus in the Southern California Bight
We investigated the potential use of open coastal habitat over the continental shelf as a nursery area for the common thresher shark Alopias vulpinus. Seven juvenile threshers were tracked using acoustic telemetry to determine their movement patterns and nursery habitat in the Southern California Bight (SCB). Tracked sharks occupied waters over the continental shelf 87% of the time. These water...
متن کاملThe complete mitochondrial genome of the big-eye thresher shark, Alopias superciliosus (Chondrichthyes, Alopiidae).
The complete mitochondrial genome of the big-eye thresher shark was sequenced using a polymerase chain reaction (PCR)-based method. The total length of mitochondrial DNA is 16,719 bp and includes 13 protein-coding genes, 2 ribosomal RNA, 22 transfer RNA genes, 1 replication origin region and 1 control region. The mitochondrial gene arrangement of the big-eye thresher shark is the same as the on...
متن کاملAcoustic tracking of bigeye thresher shark Alopias superciliosus in the eastern Pacific Ocean
Acoustic telemetry was used to identify the short-term horizontal and vertical movement patterns of the bigeye thresher shark Alopias superciliosus in the eastern tropical Pacific Ocean during the summer of 1996. Two immature female sharks, 175 and 124 cm PCL (precaudal length), were tracked for 96 and 70 h, respectively, demonstrating very distinct crepuscular vertical migrations similar to th...
متن کاملThe red muscle morphology of the thresher sharks (family Alopiidae).
A more medial and anterior position of the red aerobic myotomal muscle (RM) and the presence of a vascular counter-current heat exchange system provide the functional elements that facilitate regional RM endothermy in tunas, lamnid sharks and the common thresher shark (Alopias vulpinus). The convergent RM morphology among all species capable of RM endothermy suggests that RM position is a stron...
