                            Name one difference between a Seal and a Sea Lion.
                            Possible answers:
SEA LIONS: Earflaps, long hairless foreflippers, hindflippers rotate underneath to allow them to walk on land, swim underwater using foreflippers like wings of a bird, long smooth whiskers 
SEALS:Earholes, short, hairy foreflippers & long claws, move on land by wiggling on belly & keep hindflippers straight out, swim by steering with foreflippers and powering with hindflipers, whiskers are crimped
