The humpback dolphins’ hump is made of cartilage, not fatty tissue like a camels hump
The humpback dolphin can tolerate brackish water, often entering bays and sometimes going up rivers
Humpback dolphins mainly eat fish (e.g. pinkies, sardines, grunter) but sometimes eat cuttlefish too (e.g. Chokka)
The humpback dolphins’ long thin rostra (noses) might mean that they are extremely good at echolocation
Humpback dolphins are extremely shy and never approach boats to bow ride like bottlenoses do
A high proportion of humpback dolphins have scars that suggest shark attack
