Region: Arctic, Antarctica. Humpback Whales belong to the family of baleen wheels, which have a series of curtain-like filters in their mouths instead of teeth. Moving through clouds of krill or schools of smaller-sized fish, they suck in large amounts of water, then push the water back out through their baleens, trapping the krill inside. Sometimes Humpbacks will slap the surface of the water with their flukes or pectoral fins in order to stun prey with the shockwave.
Humpbacks are also very good pack hunters. When a pod is on the hunt, some members will blow air bubbles around a school of feeder fish, trapping them in a rough cylinder.
Other members will continue to gather more fish into the cylinder, while yet another group of pod members will circle below, making sure no fish escape from the bottom.
Once the cylinder has been compacted enough the whales will swim up its length, gulping in the feeder fish. Humpbacks will usually do all of their feeding in the summer months, living for the most part off of their reserves of fat during the winter.
Humpback Whales are generally loners; coming together occasionally to feed or mate. On the other hand, Humpbacks are regarded as being quite friendly towards other types of marine life, having been spotted socializing with other kinds of whales and dolphins. When travelling, Humpback Whales move at about 5 to 15 km per hour. Humpbacks dive to about m. They can stay underwater for 30 minutes, but on average their dives only last about 15 minutes.
Females reach sexual maturity at 5 years of age; males mature at 7. Other species will sing to attract a mating partner or herd off the female so that competing males have less chance to mate with her. Once the female becomes impregnated, she spends 9 — 18 months developing and carrying her child in her uterus womb. After several mating months, these marine mammals will travel back to their feeding grounds until the next mating season.
Note : While numerous whale species migrate from one location to the other to give birth and feed, not all species are known for making long migration trips, and some whales will stay within their local habitat all year long. During this time when the female becomes impregnated , the female whale will go through a gestation period where her child develops in her uterus.
As the child develops, it is given nutrient-rich blood through an umbilical cord until it is fully developed and ready to be born. Also, to provide the child with nutrients, the umbilical cord will help remove waste from the child to make sure the baby is growing healthily.
Once birth occurs, the umbilical cord is separated, leaving the baby whale with a belly button, just like in humans. Find More on Humpback Whales Below:.
