Everyone! Here’s the latest from my adventures at sea.
Today the crew was busy testing equipment. We tested both long-line fishing gear and box trawl netting! Both
tests were successful and we are looking forward to the real thing – more to come on this subject later. The picture below shows Scott Benson holding the box trawl net “catch.” Although it looks like group of eggs, they are actually members of the jellyfish family know as ctenophores or “comb jellies.”
We had a successful observation session today. I’ll introduce you to some of the “stars” of the day.
Common Dolphins were everywhere. We saw over 100 riding the waves on the bow of our boat. They move with great speed – especially when you are trying to take a picture of them.
Risso’s Dolphins – This is an unusual looking dolphin with a rounded head – unlike the traditional dolphin we all know. These creatures have numerous scratches and scars over their body from other Risso’s and from the squid they eat. They are gray when born and gradually become white with age.
Fin Whales – OK – I must admit – We didn’t actually see the Fin Whale but we did see the whale spouts from the three that we spotted.
Jelly Fish – We were excited to see so many Jellies – a favorite food of the Leatherback. Most looked like “Moon Jellies” but without catching them we cannot be sure of the type since there are many species.
To Do… Research one or more of the animals highlighted above.
