Two distinct behaviours have been observed in inking cephalopods. The first is the release of large amounts of ink into the water by the cephalopod, in order to create a dark, diffuse cloud (much like a smoke screen) which can obscure the predators view, allowing the cephalopod to make a rapid retreat by jetting away. The second response to a predator is to release pseudomorphs (false bodies); smaller clouds of ink with a greater mucus content, which allows them to hold their shape for longer. These are expelled slightly away from the cephalopod in question, which will often release several pseudomorphs and change colour (blanch) in conjunction with these releases. The pseudomorphs are roughly the same volume and look similar to the cephalopod that released them, and many predators have been observed attacking them mistakenly, allowing the cephalic to escape (this behaviour is often referred to as the blanch-ink-jet manoeuvre). For over a week Quinns President has been casting squid ink cloud in communications about Harlequins availability for the night match tonight at 6.30pm and has even been suggesting a forfeit. Head coach Brett Bourke and his offsider, The Germinator, quickly recognised this plush of black ink as a mind game and decided it was time for a feed of calamari. The second last game of the season at North Warrane was a torrid affair with a close and exciting finish. In the first 60 minutes the Roosters had more passion and determination than the Quinns. Early first half tries to Phil Barry, and Cyron Prouse and Some one else in the Rooster forward pack and a conversion to Jake Hyland had the half time margin tentacling out to 17 -5. Bourkes plan was working and the reigning premiers were clearly rattled. Roosters constructed their play with purpose and aggression and it seemed they would jag the Oily Quinns. The last twenty minutes saw the game almost lose the spectacle quality that had evolved from the opening. Scrappy play, ad-hoc rugby and a melei got players and spectators blood boiling. In true Quinns fashion they regrouped with some unstructured brilliance which saw them run in two tries and convert one, leaving the score deadlocked at 17 all with 3 minutes to go. Finally the relentless head high shots on Jake Hyland and his third blood nose for the game had referee, Jim gr asshopper Hobden to penalise Quinns. Hyland converted and Roosters win a nail biter 20-17 and consolidate a top four position and securing the Roosters first finals appearance in twenty seven years. In the end Bourke and Gilbank enjoyed the calamari feast as the Quinns fielded their strongest side. For the Roosters the outstanding players were many as all played with a passion that showed they do infact bleed maroon. Robert Cassboults tough running saw him pick up another King Rooster vote, With Judd the human ping pong picking up 3 points, Hyland got two points with his blood and guts game. Marc Whitfield picked up one point which was usually a man of the match performance. Jonathan Elliott and Cyron Prouse also strongly performing. Jayson Turnbridge was rested after playing for Under 17 Tasmanian team against Victoria earlier in the day. Jayson was spotted after the Roosters match chewing on a Pork Crackling bun. Thanks must go to Sam Sparrow Featherstone for organising and cooking a pork and lamb spit roast.
