nobody understands the true obsession I have with the double long nose elephant fish- I make my friends go to the aquarium with me at least once a year just to see him. my king. my silly little guy. he is my everything.

weevil and elephant fish would be best friends. but they come from two different worlds they will never meet they don't even know that the other exists my heart is BROKEN!

Daily fish fact #503

Freshwater elephantfish!

They have an organ that produces weak electric impulses and electroreceptors! They use their electroreceptors to sense their environment, though they also use their electric impulses to communicate with other individuals of their own species! They involve electricity in all kinds of communication like courtship, warning signals, to recognise individuals and to establish roles.

Elephant Fish, in: Church of Saint Martin in Zillis, Switzerland, 12th century

The painted ceiling of the Church of Saint Martin serves as a sort of medieval bestiary. Surrounding the Earth on the church ceiling is an ocean populated by an assortment of hybrid creatures, each one a land animal mixed with a fish. The ceiling boasted a horse fish, goat fish, rooster fish, etc. One of the hybrids was an elephant fish.

This picture suggests that the painter had some idea of what an elephant trunk looks like — notable since medieval Europeans didn't often see elephants. It also reflects the belief common at the time that every land-dwelling animal had a marine counterpart.

My fish, The Gooch. She’s an elephant Nosed fish, Marcusenius schilthuisiae. She is scared of metal tongs and objects because elephant fish produce electrical pulses, kind of like a sixth sense, and the way it bounces off the metal is very noticeable to them

Meet Senior Aquarist Dalton!

He's part of a team of Aquarium biologists responsible for caring for our elephant fish, Callorhinchus milii, in the Whalefall exhibit in Into the Deep/En lo Profundo.

Ensuring the well-being of these unique deep-sea dwellers is Dalton’s top priority.

Peter's elephantnose fish!

It has the largest brain to body oxygen use ratio of any vertebrate!

what’s your fav fish?

Favourite fish? That's a really hard question that I actually don't have an answer to since there's literally thousands of species of fish. I could make a list of all the ones I like but I thought I'd take the opportunity to talk about one in a bit more detail.

Image Description: a full body image of the Elephant Nose Fish, a brown fish with white stripes. It has a proboscis that looks like an elephant's trunk.

Allow me to introduce the Elephant Nose Fish, named after the trunk-like appendage on its face. Although it looks like it has a really long snout or even a nose, the protrusion actually comes from its chin. Let's take a closer look at that.

Image Description: A close up of the Elephant Nose Fish, where the protrusion is more visible as coming out of the chin of the animal.

Here you can see it a bit better. What's cool about the mega-chin is that the Elephant Nose Fish uses it for electroreception, amongst other things. It is able to actively generate its own weak electrical field using an organ in its tail, which it then detects disturbances in using electroreceptors all over its body, including its trunk!

Image description: A simple diagram of the electroreceptor structure found on the Elephant Nose Fish. There is a pore filled with a gel (represented in yellow) that connects to a bundle of sensory cells (represented in red)

Those electroreceptors are actually really cool in and of themselves: they're pores filled with a gel that has semiconductor properties (above is a diagram I drew in my notes in my first year of uni). The fish is able to detect differences in the predicted (i.e. a base assumption of no objects around) and detected fields. This system is sensitive enough that it can detect the size, distance and to an extent the material that an object is made out of. It can even detect prey under the riverbed!

I've also heard that their brains are pretty large to accomodate this and use a huge proportion of their oxygen intake, something like 60%, as opposed to the human 20%. Although, I've only really seen this in one paper of which I only read the abstract, so take that with a pinch of salt.

Sorry I couldn't really answer your question, but I hope this makes up for it! Thanks for asking :)
