References shark minisub from The Advenures of Tintin and Red Rackham's Treasure? 

a) The shark minisub appears to be something referenced in Ron Cobb's early Nostromo spacecraft known as the Snark. 

b) While Alien script writer Dan O'Bannon adored "Alice In Wonderland" and its sequel "Through the Looking-Glass", I'm wondering if the name of the Snark might well tie in with the idea of this shark mini-sub. 

c) The front part of the ship retains pectoral fins. 

d) Traces of the cockpit canopy perhaps only remains as the observation dome on the top of the ship.

e) The jelly fish merges with it to become the giant radar dish.
