Toothed Whales Bottle Nosed Dolphin Narwal Sperm Whale Beluga Whale Killer Whale (Orca)

Bottlenose Dolphin live in small groups of up to 12 have a life span of about 25 years eat fish and squid their predators include sharks, orcas, and peoples nets are in NO danger because their numbers are abundant Bottlenose Parenting Video

Narwhal the males have a very long, hollow, spiral tooth (with a few exceptions) live in cold arctic waters but are rarely seen eat fish, squid, shrimp and other marine animals they are preyed upon by humans, polar bears, orcas, sharks and walruses

Sperm Whales largest toothed whale has the biggest head of any animal named for the valuable spermaceti oil (wax) that it produces in the spermaceti organ (located in its head) scientists believe this organ is used in maintaining buoyancy and enables the whales to dive to such profound depths they also believe this substance is involved in producing the powerful acoustic clicks the whales use for echo-location and to stun their prey can dive to extreme depths and hold their breath for long periods of time hunt giant squid that live on the ocean bottom at great depths also eat fish, octopus and skate most live over 70 years ENDANGERED Sperm Whale Video

Beluga Whales live in cold Arctic and sub-Arctic waters very social animals that congregate in pods of 2-25 whales they are slow swimmers and are hunted by killer whales, polar bears, and people they hunt and eat bottom-dwelling prey, including fish, squid, crustaceans, octopi, and worms ENDANGERED

Killer Whales (Orcas) Killer Whale Video 1 largest member of the dolphin family found in both tropical and arctic waters live in small, close-knit, life-long pods very efficient hunters who find their prey at the surface of the water, eating fish, squid, sharks, birds, seals, sea turtles, octopi and other whales have been known to play with their food before eating it, or letting their food go after a little "playtime" Killer Whale Video 1

Killer Whales (Orcas) are strong pack hunters and often use echolocation to find prey you can easily tell the sex of the orca by looking at its dorsal fin
