Some more cute marine mammals entered the world recently. Over at SeaWorld San Diego, staffers used sex selection techniques to keep an optimal balance between male and female Atlantic bottlenose dolphins and brought about the birth of a brand new female calf. Three California sea lions at the Belfast Zoo became mothers after nearly a year-long gestation period. As part of a European breeding program, the Belfast Zoo has seen the birth of 10 sea lions in the last four years. Ah, breeding programs are my favorite -- where science and cuteness meet.
