They have been observed feeding in large groups near the surface, which attracts sea birds and helps research vessels find groups of hourglass dolphins. In terms of appearance these dolphins have a distinct black and white pattern which resembles the design of an hourglass, which explains how they got the name “hourglass dolphin”. An Hourglass Dolphin's main diet is small fish, squid and crustaceans.
They have conical teeth: 26 - 34 in their upper jaws and 27 - 35 in their lower jaws. Information on the diet of hourglass dolphins however is to date pretty limited but of the five individuals that have been examined they were found to have been feasting on a variety of small fish species as well as squid and some species of crustacean, for example shrimp. Hourglass dolphins feed on lanternfish, squid, and crustaceans, and have been spotted feeding in groups of seabirds and plankton swarms. Information on the diet of hourglass dolphins however is to date pretty limited but of the five individuals that have been examined they were found to have been feasting on a variety of small fish species as well as squid and some species of crustacean, for example shrimp. Hourglass dolphins also use their intuition and have been seen feeding under aggregations of seabirds and in large plankton blooms.Hourglass dolphins like the cold and they can be found in Antarctic and sub-Antarctic waters. They can reach speeds of around 22km/hr and tend to make a lot of ‘spray’ as they surface to breathe. Although they can join up to form large pods of up to 100 individuals, it’s more common to find them in groups of around a dozen or so. Both patches are connected by a thin white strip that is located near the dorsal fin. Not much is known about the hourglass dolphin's diet, but they have been spotted eating crustaceanslike shrimp, squid, and small fish. Hourglass dolphins live on a diet of fish, squid and crustaceans and feed at the surface, which often draws a crowd of sea birds and helps research vessels spot the groups of dolphins. Fast and furious. Examinations of the stomach contents of the few specimens indicate they eat mantis shrimp, polychaete worms, and various (unrecorded) species of squid and small fish. Although they spend most of their time in deeper waters, they have been seen closer to land in shallower bays and islands.Scientists are soon to undertake a complete revision of the.By supporting WDC, you can help hourglass dolphins to live safe and free.

They have also been seen feeding among planktonblooms. Their bodies are stocky yet short in length (less than 6 ft) and from the few t… Hourglass dolphins use echolocation for orientation and prey location. Hourglass dolphins are carnivores (piscivores and molluscivores).The diet of this animal mainly consists of squid, crustaceans as well as fish. Hourglass dolphins are incredibly boisterous and are known to be avid fans of bow-riding the wake of fast boats. Most of the body is black, however they have two patches, one that runs from the beak to the dorsal fin and another that starts at the dorsal fin and runs down to the tail. Interestingly, hourglass dolphins are possibly one of the few species of dolphin for which no immediate threats – not counting climate change and pollution – are thought to exist, likely as a result of living so far away from the destructive nature of mankind.As with other dolphins their daily activities are determined by their quest for food and Hourglass dolphins have been regularly sighted in areas of high productivity.
