The Iloilo Strait Has Rare Dolphins!


A dolphin of unidentified species died of suffocation after being trapped by one of the nets of the fisherman in the Iloilo Strait. The dead mammal was then brought to SEAFDEC, a marine research organization in Iloilo. The dolphin was later identified as an Irrawaddy dolphin, one of the rarest in the world.

Mrs. Louelle Dolar-Perrin, a Filipina marine biologist specializing in marine mammals associated with the Silliman University Marine Laboratory in Dumaguete City,Negros Oriental, handled the case of the dolphins and NatGeo international bought the rights to her study. She studded the Irrawady population and she found out that only 30-45 of them are left. Frequent ferry boats (Weesam, Supercat, Oceanjet) and cargo jets disturb the animal's feeding time and mating rites. Some of th edolphins were later found lifeless and mutilated probably by the blades of the same boats that passed Iloilo Strait.



The dolphins can be sighted 6:00 -7:00 in the morning by the Siete Pecados in Guimaras.

Mrs. Perin is also thinking about establishing a new species. The dolphins in the Iloilo Strait could have been there for thousands of years already so they might have developed new adaptations (eg. larger back dents) worthy of being named a new species.

When Mrs. Perin presented her study to the LGU of Guimaras, a joke was cracked by the officials saying that a civil war might break out over the new name. What do you think? Orcaella guimarasis or Orcaella ilonggonensis?
