The Blue Fleet

The blue fleet is a term coined by Sir Alistair Hardy to describe a community of creatures that float around in the oceans including the bluebottles, sea swallows, violet snails, blue buttons and by the wind sailors. Most people who frequent a beach would have come across at least some of them, probably the bluebottles or the by the wind sailors.

All of these creatures float around on the oceans with the sea swallows feeding on most of them. The venom of the blue bottles do not affect the sea swallows as they eat the tentacles and use the toxins as their own defense, making them more dangerous than the blue bottles!

This project only allows the following obs to be added

  • Physalia physalis - Blue bottle
  • Porpita porpita - Blue button
  • Glaucus atlanticus - Sea swallow
  • Velella velella - By the wind sailor
  • Janthina janthina - violet sea snail
  • Recluzia rollandiana

The banner for this project shows all of these critters.

Blue Fleet Challange - Find Any 3 in 1 Day

While adding the blue fleet species I saw an interesting comment on one obs Fun, so 3 of the Blue Fleet in the one little bay on the same day so I thought I would highlight that as a fun challange for us!

I often see the blue bottles and by the wind sailors on one day and the next one with the most obs is the Violet Sea-Snail (Janthina janthina) so that would probably be the easiest to find when you see the other 2! The Janthina janthina on the banner is a live one so they probably will not look like that.

When you do find any 3 in 1 day, add that info in the comments of this post so we all know :)

Happy hunting!

Mass Washups of By the Wind Sailors

It seems that at the moment there are mass washups of By the Wind Sailors on the West Coast of New Zealand.

One week to travel from Foxton to Rahotu or a different event?

13 October 2017, NZ Herald reports of lots in Greymouth but the article does not say what day this occured.

There is also a Project Assessment Tool buried in here that I have been playing with

Feel free to add any comments to help us keep track of the Blue Fleet :)
