1.52 meters. Playa Matapalo (between Sugar beach and
Playa Ocotal), Guanacaste. Medical treatment for two
days until natural death. Without superficial damages,

(Puntarenas). The head was cut off after stranding.

Grande, Marine Park Las Baulas, North Pacific. Juvenile
female alive. Death after two days of treatment due

Case 2003-1.
May. Stenella coeruleoalba (Striped dolphin). One male
juvenile individual, approximately 3 years old, found
alive in Playa Uvita, BahÌa Ballena, Puntarenas,
South Pacific. It received medical veterinarian treatment
during 3 days, until his death at 12:45 p.m. of the
third day. It was transported complete to the Universidad
Nacional de Heredia's Pathology installations, where
a necropsy was done. Nematode parasites were found in
its lungs, while stomach ulcers and intestine parasites,
as well as a bacterial infection among pectoral fins'
articulations were found. Clinical analysis revealed
a practically non-functional immunologic system, with
most white-formula integrants at zero levels.
Case 2002-1.
April. Steno bredanensis (Roughed teeth dolphin). Massive
stranding of 37 dolphins in Playa Cedro (CÛbano).
34 individuals were returned to sea with help of Moctezuma
and Cabuya communities. An individual skull was collected,
as well as samples of different organs for necropsy,
which revealed no bacterial or viral infection nor internal
damages. The organs were healthy and food was found
in the stomach, mainly consisting of fish rests. These
results suggest that the massive stranding was caused
by external factors instead of internal ones, such as
the group leader being mislead.
Case 2001-10.
November. Striped dolphin (Stenella coeruleoalba) juvenile,
female, found alive in Playa Hermosa de Guanacaste.
No wounds or external markings. Was treated during 3
days until it died. Reporter: Hotel El Velero.
