This summer the Brookfield Zoo’s bottlenose dolphin habitat will reverberate with the chatty whistles and playful leaps of a new calf — the first expected to be born there in over a decade.

For a $15 donation a Madagascar hissing cockroach can be named. The names will appear on a naming board displayed outside the Hamill Family Play Zoo. Names must be submitted by 5 p.m. on Feb. 5.
