LETS GO!!! YES!!!

Zebra sharks got their name from the stripes they have as pups which become spots when they become adults.

sharks are just like giant kitties tbh. they’re just curious silly little creatures. they’re just interested in what’s around them. they bite you the same way a cute little kitty bites you. they’re just trying to get to know you. why do you hate them so so much they think you’re interesting and they’re cute. leave them alone

Daily Cephalopod #2

Daily Jellyfish: Day 3

Atolla Jellyfish

Fun Facts

This species of Jellyfish uses bioluminescent defense technique in which it launch several bright flashes as its being attacked in hopes to attract a larger predator interested in its attacker more then itself.

For the previously said reason, this jellyfish has earned the title of the alarm Jellyfish.

They are considered deep sea creatures, living between 1000m to 4000m in depth around the globe.

Is it known what baby coelacanths look like??

Yes! An expedition filmed one in Manado Bay, North Sulawesi, Indonesia in 2009!

"It was measured by a laser beam from the R.O.V. to be 31.5cm. The fish was positioning itself in a small cave."

Wake up babe new fish dropped

Today is Wet Beast Wednesday!

Today’s wet beast is: Man-of-war Fish

Olive’s wet beast fact: this little fishy has evolved to live within the extremely dangerous tentacles of the Portuguese Man O’ War. It is here that the fish feasts upon their gonads. Happy Pride.

Stay tuned for more Wet Beast Wednesdays!

The Sea Creature of the day is the Moon Jelly!!

These absolutely beautiful creatures can essentially be found anywhere in the world and are one of the most commonly seen species of sea jelly.

A fun fact, though the immortal jellyfish is most commonly known for it, moon jellies too can revert back in their life cycle to the polyp stage if exposed to environmental stress. Through this, a single jelly can keep itself alive for a longggg time.

Vessel sound is temporarily causing hearing loss in squids

Globally, anthropogenic sounds have become louder and more persistent, however, little is known about how invertebrates detect and respond to human-made sound. Now, new research shown noise associated with boats causes  causes temporal hearing loss in squids across different stages of their life cycle.

The hummingbird bobtail squid (Euprymna berryi) has a short lifespan of at least 6 months, which make them a convenient animal for lab studies. Hearing and behavioural observations were made by researchers before, during and after 15 minutes of vessel sound playback, to test how these squids react to noise pollution, and noted that these squids decrease their hearing sensitivity after exposure to noise, and particularly noise affected juveniles. Juvenile squids experienced an important hearing loss sensitivity after noise exposure between 400 and 800 Hz, while adult and mature squids decreased their sensibility after 200 to 600 Hz exposure, showing more resistence. All squids recovered auditory sensitivity within two hours.

Researchers aim the inclusion of cephalopods within management and policy, because anthropogenic activities and associated sound levels in the ocean are increasing, while the role sound plays in cephalopod life history is only just beginning to be understood.
