Whales

Whales use sound to hunt, navigate, and communicate. Toothed whales use sound to hunt and navigate. Baleen whales use it to communicate. Baleen whales communicate with songs. Only males have been recorded to sing (mating perhaps). These songs consist of groans, moans, roars, sighs, and high pitched squeals. These songs can last 10 minutes or longer. The frequencies range from 20-9000 Hertz. These songs are also thought to be used to identify individuals and for long range contact or warn other whales of something. Baleen whales don’t have vocal chords so they use voice boxes to make sounds. The echolocation sound waves are made from sinuses in the head and then are received by an oil filled chamber in jaw or the middle ear. Echolocation theory’s suggests that it may be used to stun or disorient prey in hunting. Also it is thought that echolocation may provide toothed whales and dolphins with a 3-D view of the world.

Humpback Whales

Focusing on the specific marine life of humpback whales and their migration pattern and echolocation.

Type: MammalDiet: OmnivoreSize: 48 to 62.5 ft. Weight: 40 tons Group name: PodProtection status: Endangered

Humpback Whales are found near the coastlines feeding on shrimp-like krill, plankton, and small fish. They communicate using sound that can echo and travel to a great distance. Humpback whale uses this to attract potential mates. Humpback whales are powerful swimmers, and they use their massive tail fin, called a fluke, to propel themselves through the water, and out of the water which is known as breaching. Humpbacks migrate annually from summer feeding grounds near the poles to warmer winter breeding waters closer to the Equator. Mothers and their young swim close together, often touching one another with their flippers with what appear to be gestures of affection. Females nurse their calves for almost a year, though it takes far longer than that for a humpback whale to reach full adulthood. Calves do not stop growing until they are ten years old.

Summer -cold polar waters-feeding on Antarctic krill. Fall -migrate to warm tropical waters Winter -whales mate and calve-Baleen whales live off a layer of blubberSpring-return to their feeding grounds with their calves

Humpback whales cover over 3,000 miles in one seasonal migration traveling at a speed of approximately 3-9mph

Breaching occurs when a Humpback jumps out of the water entirely, landing with a giant splash- to scare off predators.- to get rid of parasites- for recreation
