Species You've Dived With and Locations

[Thalassamania]

There are many organisms whose range and distribution is temperature limited. That said, these (and many temperature tolerant species) undergo light level mediated diurnal vertical migration and are found shallower as you move north.

I'm aware of vertical migration (which goes on throughout the planet-underwater that is). The ratfish for example are more plentiful at night here but in some locations they are out shallow in the daytime even on good viz days as well so I think in their case temperature must play a greater role as our waters are a few degrees cooler than N. Cal.

Sixgills aren't found shallow at night in warmer waters as far as I know.

Light vs temp I'm sure is species dependent as to which plays the greater role.

 

[Thalassamania]

With ratfish I really don't know. We used to see them often off the end of the pier at the Moss Landing Lab, we figured they were headed south, hit the canyon wall and just followed it up.

No you are not. Just look at in terms of species per dive, you are way, way, ahead of me.

faridefan1 / Thalassamania,

Good point just worked out my "average species per dive" on my rookie 6 species sightings so far (less than 100 dives) -- and am now not quite so jealous of others amazing lists ... SSharkks !!

:cool2:

 

[Code Monkey]

Man, I would kill to see a hammerhead shark!

I don't think you get to call yourself a rookie.

Thanks but boy, I wish I could have been diving my whole life like you and many others. Living in Utah is great but I was a sloth and did not "discover" scuba till I was 57. But at least I am there now.
