Dolphin Behaviors ~ Tail Slapping, or "Lobtailing"

Lobtailing is a behavior commonly seen among wild dolphins (and even larger whales, such as humpbacks). In this display, the dolphin will lift its tail flukes, then slap them against the water's surface, usually creating a loud "Smack!" or "Slap!"

The meaning of this behavior isn't completely known. Some say that this is a dolphin "warning signal." Others believe that lobtailing is the way to get the attention of other dolphins, or sometimes even people. Still others suggest that this may be a sign of agitation or possibly even aggression.

The beginning of lobtails can vary. Sometimes, the dolphin will, without first surfacing for air, lift its flukes above the surface, then bring them down on top of the water. Other times, the animal will surface for air normally, then, as it dives back under, with lift its peduncle and lobtail.
