Subject: Kogia in South America: new publication

Dear colleages:

The following paper was recently published in the Colombian Academy of Sc=
iences Journal, regarding a review of the genus Kogia in South America.

Mu=F1oz-Hincapi=E9 MF, Mora-Pinto DM, Palacios DM, Secchi ER, Mignucci-Gi=
annoni AA. 1998. First osteological record of the dwarf sperm whale in Co=
lombia, with notes on the zoogeography of Kogia in South America. Rev. Ac=
ad. Colomb. Cienc. 22(84): 433-444.

The dwarf and pygmy sperm whale (Kogia spp.) are known to occur in pelagi=
c waters of all tropical and temperate oceans, but their record in South =
America is fragmentary. We reviewed the literature for records of both sp=
ecies in South America as part of documenting the first osteological reco=
rd of the dwarf sperm whale (K. simus) in Colombia. The new Colombian spe=
cimen is only the sixth recorded so far from the Pacific coast of mainlan=
d South America, and the first osteological voucher of the species for Co=
lombia. The biological information of the two species in South America ha=
s increased in recent years as a result of increased presence of research=
ers in the region. A total of 21 records of K. breviceps, 23 of K. simus =
and 5 of Kogia sp. were studied, to analyze the species=B9 zoogeography. =
Both whale species were found in most coastal nations of the Caribbean, A=
tlantic and Pacific, but appear to be rare in Uruguay, Argentina and Chil=
e. No records exist for Venezuela, Trinidad, Guyana, Suriname, and French=
 Guiana. Most of the records were in waters north of the Tropic of Capric=
orn (23.5=B0S); differences in tropical distribution observed when compar=
ing the latitudes of records from the east coast with the west coast are =
probably related to the prevailing currents and water masses. The distrib=
ution of both species of Kogia appears to be tied to the warmer water mas=
ses, and characterized as tropical pelagic, ranging as far south as 15=B0=
S on the Pacific coast and 33=B0S on the Atlantic coast.
