Bottlenosed dolphins get their name from their that are short and stout. They have a thin, pale line running from the eye to the flipper and a darker grey line on the upper back. The belly is off-white an speckled with grey spots.
They often join bathers an come to the aid of newbom or injured dolphins. Pods of 20-50 dolphins feed on fish and squid, which they hunt by driving their prey into a 'spearhead' formation, before encircling them.
Sadly, they often become entangled in shark-nets. Concern exists that some populations may be declining, due to the high toxin levels in polluted seawater (toxins are offloaded to young through milk).
