Dolphin population uses different whistles to beat noise

A recently recorded population of Indo-Pacific Humpback dolphins has been observed using their own distinct whistles which have longer durations, lower frequencies and fewer inflection points.

Resident fin whales calving in the Gulf of California

Fin whales (Balaenoptera physalus) have resident populations in three different regions - including the Gulf of California.

Organic Contaminants cross the placental barrier in Indo-Pacific humpback dolphins

A new study by Xiyang Zhanga, Fengping Zhana, Ri-Qing Yu, Xian Sun and Yuping Wu has found that pregnant Indo-pacific humpback dolphins transfer organic contaminants to their unborn offspring. Their investigation found that polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCB) were all found in both the mothers and foetuses.
