More Updates from the Cruise!
Hey Kids! Squirt here with more updates from the cruise!
Look at this adult female anglerfish! This was an exciting find for the scientists because she is so large! These fish are normally around the size of a golf ball but this lady was a total of six inches! That's half the size of your ruler! While this may seem small for you and I, in comparison to other fish of the same species, it's actually a size record! The other interesting thing about this female anglerfish is that she has a male attached to her! If you look closely at the bottom left side of her body you can see the male. The male anglerfish of this species are parasitic on the females, meaning that they will bite the female and hold on. Eventually, the male's lips will become permanently attached, and is then sustained by the female and only used for reproductive purposes.
These anglerfish are also the only group of fishes that evolved two entirely different bioluminescence systems. The "beard" that hangs off the fishe's chin glows in the dark by light produce by the fish itself. The lure on her head is called symbiotic bioluminescence, meaning its light is produced by bacteria on the lure, not the fish itself. It is extremely rare to have both biolominescence systems!
Time to welcome back some fish we've met before! Say hello to the moonfish! These fish are usually found out at sea as juveniles. As adults they can be found closer to the shore.
Let's not forget to welcome the telescope fish! We've talked about them before in a previous blog post! You can find it here; http://www.outreach.deependconsortium.org/index.php/kids-blog/entry/glowing-water
This fish was trawled from between 1,200 and 1,500 meters in depth!
Until the next update! Thank you for following us on our journey through the deep!
