How do you distinguish between Stubb and Starbuck

Starbuck is pragmatic. Starbuck comes across as serious and interested in practical ideas rather than dreams or obsessions. Although the only person who openly opposes captan Ahab, he remains loyal to the end. Stubbs is much more care-free than Starbuck. Unlike Starbuck he keeps his opinions hidden behind jokes and his light hearted manner. Starbuck tends to sound rash and forceful to the men while Stubbs coaches his orders in humour making him a likeable character to others.
