|8||Moreno & Morón (1992)||2.243||2.628||Largest of 18 with TL range from 1.62-2.63 m, mean 2.13 m. Standard length 80.7-85.4% of Tl. Pectoral fin height (not defined) decreasing from30.7 to 22.5% with increasing TL.|
Caught at 6 am on 21 Mar 1998 near Midway Atoll. Slides provided for scaning by James Aliberti, Refuge Ranger, US Fish & Wildlife Service. Dave Ebert suggested that it is I. paucus.
|10||Dodrill & Gilmore (1979)||Fem||est. 3.12-3.34||Live adult female with a missing eye was discovered partially grounded in the surf at Melbourn Beach, Brevard County, Florida (28 deg 00' 05" N, 80 deg 31' 20" W at dawn on 28 December 1975.|
|Ebert (2001)||Fem||3.0-3.3||300||Captured in 1990 approximately 10 miles norht of Santa Barbara Island, Santa Barbara County, CA, USA by T. Athens, a commercial longline fisherman. It was caught at a depth of about 30 m in water over 800 m deep.|
|Ebert (2001)||Fem||3.3-3.6||Caught in 1988 approximately 6 miles southeast of Anacapa Island, Ventura County, CA, USA. The specimen was dressed and shipped to a Boston MA seafood buyer, who recognized it as longfin mako and returned it to the fisherman in California. The firm-bodied flesh of the shortfin mako is highly desirable while the that of the longfin mako is mushy and of poor quality.|
Jeff Seigel p.c.
|Caught off Redondo Beach CA, USA on July 13, 1996; 23 kg (50 lb) blue shark found in stomach. Dave Ebert suggested it could be I. paucus.|
IGFA 1989 p.94
|Caught on March 14, 1943 off Major Island NZ by B. Ross. Photo provided by P. Guillanton, who suggests it could be longfin mako, Isurus paucus. Both Dave Ebert and Clinton Duffy suggested that shortfin mako identification more likely despite apparent long pectoral fin.|
|Taken by James Melanson of Montauk NY (USA) on Aug. 26, 1979. Photo provided by P. Guillanton. Previous IGFA record. Dave Ebert suggested that it is I. paucus.|
|16||Casey (1986)||Fem||3.10||3.30||409||The pregnant female was caught in Mona Passage in January 1983 and contained 8 near-term embryos with TL range 1.14-1.22 m (see #3 above)|
|Douglas Long||?||3.38||Caught off Taiwan. Waiting for date of capture and photo of set of jaws..|
|17||Gilmore (1983)||Fem||3.025||3.366||3.728||351||Largest (and pregnant) of 13 specimens (SL = 1.675-3.035) from 1975-1980. Caught 3 December 1980 on a 16 km swordfish longline. The greatly expanded and vascularized left uterus suggested that a second had been present but was apparently aborted during capture.|

|19||Dodrill & Gilmore (1979)||Caught on 20 April 1978 by William Minuth of Fort Pierce. Collected from the Florida east coast on drifting longlines set for swordfish (Xiphias gladius) over 200-400 m near the western edge of the Florida straits between Jupiter Inlet, Palm Beach Countr and Sebastion Inlet, Brevard County. Was identified from severed head.|
|Jim Boudon (2005, homepage)||?||3.7||On May 5, 1999, a large (estimate 3.7 m) female mako was caught and identified as a longfin mako using the standard identification key. Identification was questionen, click here for details.|
