Simon hasn't completed a profile. Should we look for some other people?

Simon Berrow: How do you save a shark you know nothing about?
Junichi Parker and Boeseman (1954) estimated a basking shark could filter 1500 cubic metres per hour. More recently simms (2008) has revised that estimate down by 41%, but I guess the truth is we are still trying to work this simple statistics out. No need to be abusive and personal. I think I produced a lot of facts and figures in a short talk and sometimes the analogies don't always work.

the mucous (slime) is probably used to prevent settlement from algae and invertebrates (ant-fouling) as well as lubricating the sharks movement through water to reduce energy expenditure. Mucous also has defence properyies against infections, damage etc in other fish. from talking to fishers and ex-basking shark fishers that there may be a pheromone in the mucous as once a shark has been caught in a fishin gnet is is more likely to catch other sharks compared to a net with no sharks caught. thi seffect is seasonal an dmay reflect biologically active ingredients n the mucous used to display breeding condition or attreact mates !!! So much to know about slime/mucous !!
