Do It For Me

Baby Starfish — Reproduction in starfish is external. Millions of eggs and sperm are ejected into the ocean where they mix and develop into larvae. The larvae are transparent and bilaterally-symmetrical. The tiny starfish are carried miles on the ocean currents for the next couple of months as they develop, swimming in the sea and eating phytoplankton. There is no back or front on a starfish and they don’t have to turn round to change direction. Starfish move around by using a complex hydraulic system involving hundreds of tiny tube feet instead of muscles.
A turtle survived a 15 minute fight with an alligator that failed to break its protective shell. An alligator bites down with a force of up to 2,900 pounds of pressure but despite its strength, this reptile was still unable to crack the turtle’s shell. The Eastern River Cooter’s shell managed to protect as it lay helpless in the alligator’s jaws. Although the shell protects turtle’s from most predators, larger animals such as crocodiles, alligators and even jaguars are normally able to crush the carapace in order to get to the reptile’s body.
