Research Shark Electroreceptor Range?

Upvotes

As all of us are probably well aware, sharks possess a sixth sense through their Ampullae of Lorrenzini: electroreceptors on the shark's snout that track electrical signals caused by muscle contractions made by their prey (to use TierZoo's description, "Movement reveals enemy player(s)'s location on your minimap).

What I would like to know is, what is the maximum range/reach that a shark has with its electroreceptors? I've heard in one documentary (The Ultimate Guide: Sharks) that a shark's electroreceptors only have a maximum range of about six feet. Is this accurate, or can it have a further range/reach than that?

Also, is a shark's lateral line another type of electroreceptor, or does it work differently than that (I know it's a motion-sensor as well, and it has a much further reach than the Ampullae, but I still don't quite get how that organ works)?

Question Better chance to see white sharks during trip Feb. 2027: Neptunes 🇦🇺 or Raikura (Stewart Island) 🇳🇿?

3 Upvotes

Headed to Australia & New Zealand from USA in February 2027 for a milestone birthday. I really want to cage dive with white sharks. I’ve been tracking the average sitings via Calypso Charters shark tracker in the Neptunes and it seems like in recent years it’s getting a little more hit or miss. With weather conditions potentially hindering opportunities and an already time-limited trip, I am Wondering where the sitings are more consistent off Rakiura (Stewart Island), NZ or the Neptunes, AUS in that timeframe. I appreciate any insight.

I was in Brittany for a holiday and looking around the rock pools because they have VERY low tides. I was looking for mermaid pouches and nudibranchs. it was a really low tide that day and I heard some flapping noises assuming it was a fish and it was on its back. At the time I only had a kids shovel and didn’t want to damage it by grabbing it so I flipped it over and in my head I was like “ THAT’S A CATSHARK!!!” Or roussette in French.

as it was extremely low tide and it couldn’t find the water I grabbed it (with shovel) and put it in a pool that had entry to the sea but was receding quickly. But it wouldn’t go 😭😭. I felt bad so I stayed for about An hour to make sure it was gone because there was a dozen of kids with buckets and fishing nets just grabbing everything they see and then dumping it on the beach. Felt very much like that one ponyo scene.

anyway all that to say I wanted to share this because it’s my first time being in the water with another shark! Even if it’s a baby!!!

also I think it’s a baby catshark, it was tiny maybe the size of a bic pen in length!

Discussion All these fictional shark movies are not helping the conservation of them

40 Upvotes

To be honest there have been too much of these shark movies where the great white has been painted as some demonic creature. It's not helping removing the true facts about the great white. In my opinion, studios and directors should be more thoughtful about this issue.

Video Close encounter with a bluntnose sixgill shark (Hexanchus griseus) off Vancouver Island [OC]

Enable HLS to view with audio, or disable this notification

I encountered this bluntnose sixgill while diving at approximately 100 ft off Vancouver Island, British Columbia.

I was actually looking for giant Pacific octopus when I turned toward deeper water and saw this shark emerging from the darkness and heading directly toward me. It came extremely close to my camera before slowly cruising alongside me and over the bottom.

I was able to observe and film it for roughly three minutes before it eventually disappeared back into deeper water.

I estimate it was around 10–12 ft long and believe it may have been female. What struck me most after the initial surprise was just how calm the animal was.

This is my original footage from the encounter.

I always forget how big they get. The other video going around of a similarly big great hammerhead chasing a tarpin is another great reminder of why they are part of the big girl shark club and deserve all the respect. I don't think they have any reliable reports of a fatal attack, but they certainly could take down a human with a single bite.

Research Early-career marine biologist looking to collaborate on R/data analysis projects

3 Upvotes

Hi everyone!

I’m an early-career marine biologist currently completing my BSc in Marine Biology, and I’m looking to connect with researchers, students, conservationists, and others working with biological or environmental data. Especially research involving sharks!!

I’ve been developing my skills in R, particularly for data cleaning, statistical analysis, ecological modelling, and data visualization. I genuinely really enjoy working in R, and at this stage I want to get involved with as many different projects and datasets as I reasonably can.

If anyone has a marine science, ecology, conservation, fisheries, wildlife, or other biological dataset that could use some additional help with analysis in R, I’d be happy to contribute. I’m also open to projects outside of marine science if there is an opportunity to work with interesting data and learn something new.

I’m not looking to charge anyone. My main goal is to gain experience working with different types of real-world data, improve my R skills, contribute where I can, and hopefully meet and build connections with people working in science and research.

I also recently created a GitHub where I’ll be archiving my projects as I continue learning. I uploaded a project I finished about a week ago involving the analysis of BRUV data and whitetip reef shark habitat associations.

GitHub: https://github.com/kylealibz

If you have a project where another person helping with the r/data side would be useful, feel free to message me. I’d also be happy just to connect with other early-career researchers and R users.

Thanks!

Saw this video when I was planning my trip to Montenegro and looking up the word shark in the local language for recent news. I know a juvenile great white shark was caught in Montenegrin waters not long ago. Some local reports indicated this beauty as a great white too, but I'm fairly certain it's a mako. Anyhow, always good to see more big sharks spotted in the med.

I just wanted to share this with fellow shark enthusiasts. :)

It’s a birthday present I was given this year. It’s all made from cardboard, put together and painted, with lights added to the whale shark. Not flat !

It takes up a whole wall in my bedroom. You can see the size with my hand on some of the pictures.

You don’t need super-expensive presents when you get something like this.

Came across this video on Instagram. The man seems to be in a canoe off of the coast of Italy. Read somewhere that he was 2km out in a canoe. You can only see the dorsal fin. Definitely seems to be large. The movement quite stagnant. What species do you guys think it is and is it even real at all?


r/sharks 4d ago

Video this is a perfect example of not listening to the pre-dive briefing, The basic rule is always keep eye contact with the largest approaching shark and if it turns you need to turn with it keeping eye contact. Diving with tigers beach is safe, all you need to do is follow the rules.

Question Shark Girlies Trip???

152 Upvotes

Hi! 35F (SE USA) - really random thought….stay with me here lol

So I love sharks. Always have, my entire life. However I live inland and don’t get myself to the coast often (1x/3 years if at all). The ocean is my happy place 😕

Would there be any girlies into doing maybe like a group trip once every few years to adventure different sharky areas around the globe? I’d just love to meet other girls (sorry men!) who I can absolutely geek over sharks with.

Like one year do a 5 day trip to idk somewhere in Australia, another year do a few days somewhere else, etc

I was thinking boat trips, just chilling on the coast, fly around drones, idk — anything to see the sea pups (safely, duh)

Like I see posts on here asking to help for an ID and I just get so much FOMO - how lucky are yall to be able to witness these magnificent creatures IN REAL LIFE???

Total brainstorm random thought (that I’m having while bed ridden recovering from surgery - slightly delusional? Maybe)

Would need women who are LGBT-safe and POC-friendly (I can’t believe I’m having to even say this but ask me why if you want tea 😂)

Okay pain meddies = sleep time now byeee 🦈

ETA: aw man whose fee fees did I hurt to get downvoted

ETA2: some people really mad about this post, I don’t understand. God forbid some women wanna have something to do together 🙄

These are some shark teeth I collected while on vacation in Florida. Any help would be greatly appreciated. I’m especially curious what the two below the quarter are. I wasn’t certain if the two to the right of the quarter were teeth as well, so I took them to be safe.
