Daily fish fact #765

Lumpfish!

Though they lack a swim bladder, they spend considerable amounts of time in the upper and middle parts of the water column, as well as on the seafloor. They make annual large migrations between deeper open water and shallower coastal breeding grounds.

GLOW IN THE DARK FIREFLY SQUID ENAMEL PIN KICKSTARTER

Oh okay, kickstarter approved it right away! Limited to a production run of 100, final pin might vary slightly (either the sparkles will have to be larger or they'll have to make the pin slightly larger, they're getting back to me on that)

MOONLESS NIGHT INCREASE COOKIECUTTER SHARK BITES

Cookiecutter sharks are well known for feeding on large animals, and leaving a cookie-cutter-shaped wound, hence that comically name. These are small and dark sharks, typically found in deep tropical and subtropical waters. Despite their small size, these sharks can pose a significant threat, although rarely. Of the seven reported cookiecutter shark attacks on humans worldwide, six occurred in Hawaiʻi. A new research connect the interactions between cookiecutter sharks (Isistius brasiliensis) and humans, particularly among channel swimmers in Hawaiʻi. The study showed how environmental conditions such are moonless night can increase the likelihood of these attacks.

The nocturnal feeding behavior and zoogeographical habitat of cookiecutter sharks greatly reduces interaction of this species with live humans. However, the growing popularity of channel swimming in Hawaiʻi and swim start times have contributed to an increasing likelihood of live human and cookiecutter shark, according to the researchers, moonless night sky is a significant risk factor for night swimmers.

Sweet dreams!

Sharks often congregate beneath ships, especially at night when the ships are lighting the water. This is because plankton is attracted to the light, which essentially draws the successive links in the food chain! Plankton means fish, fish means sharks. I discovered on this night that I could also catch sight of these guys on the occasion that my porthole dipped below the surface, swimming right next to my head while I sleep 😴

Lungfish :) Used to not think about them very much, thought, “I should think about them more,” went to the aquarium, saw one, got hit with lungfish love and appreciation like a TRUCK. They’re amazing fish, very seldom talked about here compared to coelacanths! They’re even more closely related to tetrapods than coelacanths are, most have these silly long fin limbs which would look cute in teeny tiny long striped socks, they’re extremely hardy animals! Some species can survive for months or even YEARS in the mud at the bottom of a dried up body of water, breathing with the use of their lungs! Their lungs have air vesicles just like tetrapod lungs, and as a matter of fact all lungfish species besides the Australian lungfish must breathe air periodically as their gills are not enough. They can even regrow their limbs?! They’re mighty cute too, they’re even more snakelike than snakehead fishes in my opinion. They ought to be appreciated :D

oh i am absolutely a lungfish convert. i love their little feet! this one's an australian lungfish, and i chose it because the reference pic i used had such a charming little smile. thank you for introducing me to this lad

VERY IMPORTANT a dam in the Netherlands, the weerdsluis lock, is directly on a migratory path for spawning fish. They have a worker stationed there to open the door for the fish, but they can take a while to open it. So to keep the fish from getting preyed on by birds they installed a doorbell. Only, the fish don't have hands to ring the doorbell. If you go to their website, they have a LIVE CAMERA AND A DOORBELL that YOU RING FOR THE FISH when they're waiting, and then the dam worker opens the door for them! I can't express how obsessed I am with this. look at this shit. oh my god.

Please check on the fish doorbell once in a while :)
