A new sensory organ has been discovered in rorqual whales. The discovery may help explain the great success of their ‘lunge-feeding method’. Rorqual whales are a subgroup of baleen whales that includes, blue, fin, minke, and humpback. They are known for their enormous size, and a accordion like layer of blubber extending from their snout to their navel. The organ was discovered at the tip of the whale’s chin, in the ligamentous tissue connecting their jaws.
The West Indian manatee living in Florida are protected under federal law by the Marine Mammal Protection Act of 1972 and the Endangered Species Act of 1973, as well as the Florida Manatee Sanctuary Act of 1978. Manatees grow to as large as 1,200 lbs and can live as long as 60 years. As they are long-lived animals, they have a low reproduction rate, coming to maturity around five years of age and producing one calf every two to five years.

After thirty years of service, some workers may never want to work see their employer again, but Rajan the elephant who is retiring at 60 years old, doesn't want to leave his boss behind. Replaced by motorised boats, the five tonne Asian elephant no longer needs to swim miles as a sea taxi around the Andaman Islands in the Indian Ocean. So now he swims alongside his human keeper, known as a 'mahout', who has used him as a ferrying service for over 30 years.
The giant isopod, known scientifically as Bathynomus giganteus, is the largest known member of the isopod family. It is very closely related to the small pillbugs that you can find in the garden. It is a carnivorous crustacean that spends its time scavenging the deep ocean floor. Food is extremely scarce at these great depths, so the isopod has adapted to eat what ever happens to fall to the ocean floor from above. It will also feed on some of the small invertebrates that live at these depths.
