A single bumphead parrotfish creates approximately 200lbs of sand every year. There are 120 (thereabouts) in this school at Sipadan which create about 24000lbs of sand a year! about the same weight as a school bus or three African Elephants. There's a link to a longer video in the comments. Thank you for the beaches bumpheads.

Hi. I'm coming into possession of a large fish tank and thought it would be cool to keep a Wandering Sea anemone. Problem is that no one seems to sell them and I don't know how to find one myself. I'm curious about whether someone could sell or find me one or at the very least tell me where they are commonly found. (I live in Nelson New Zealand) Thanks.

Hi all, I’m a solo developer (not a marine biologist, which is exactly why I need your eyes on this).

I’ve spent about a year and a half building EcoAquatic (ecoaquatic.org), a non-commercial, open tool for tracking fish species and aquatic life in South African waters, no cost, nothing for sale, just something I made. It pulls real data: the GBIF taxonomic backbone (3,000+ species with confirmed SA occurrences), live IUCN Red List conservation status, and FishBase/SASSI info, shown on an interactive map alongside marine protected area boundaries. You can log a sighting with a GPS location, and citizen-scientist sightings go through a moderation step before entering the dataset.

What I can’t judge from the dev side is whether it actually reflects how people who know the field would record and use observations. So I’m asking the people who’d know:

* Does the sighting workflow capture the fields you’d actually need (habitat, depth, confidence, etc.)?

* Is anything scientifically off, oversimplified, or misleading?

* What’s missing that you’d expect to be there?

Have a look here: [https://ecoaquatic.org\](https://ecoaquatic.org) (heads up, it needs a quick free account to get in 30-second sign-up, nothing commercial).

It’s an early build and rough in places, and critical feedback is the most useful kind. Comments here are ideal. If anyone would rather give more structured feedback there’s a short form, which I’m happy to share with anyone who wants it.

Thanks for reading.
