1. Both predators and prey animals use camouflage to their advantage.

Prey animals blend in with the background, so hungry predators pass right by them.

🧵 Start of a thread with some amazing videos on #Camouflage.

I like this one. 🙂

2. But predators use camouflage too.

The striated frogfish (Antennarius striatus) walks the seafloor right up to its unsuspecting prey.

It has a prognathous mouth that launches an attack on prey in as fast as 6 milliseconds.

1. Life is so delicate.

We conquered the planet and that gives us a responsibility to preserve all species.

Viz: #Kaveri river watershed 😍

I would be posting some #maps about the river with finer details in this thread in coming days! Bookmark.. Image
Data: SRTM
Software: QGIS
One of the biggest engineering works in Kaveri river is the Kallanai / Grand Anicut system. It was not constructed in 1 step & most of the structure that we see were erected during British era

Economic Agility in the Face of COVID19 and the Soul of the Ugandan Economy: A Personal Reflection

So, the "COVID Fish" is ready for harvest. A few months ago, I shared a brief story on how the race for economic survival had forced me to venture into #fish farming. A thread...
When #COVID19 erupted, I initially thought that it would be a passing wave. In March 2020, I travelled to Germany in spite of the unfolding global public health risk. I was only lucky that Uganda went into full lockdown just 2 days after I had returned.
As per the Ministry of Health's guidelines, I self-isolated for 2 weeks since Germany was a high-risk country. I also invited the medics to test me and I tested negative. However, the worst was yet to come. These were the longest 2 weeks of my life and a full lockdown was imposed

Today, on #TheMisplacedMenagerie -

We report the exotic (for #India) apple #snail, #Pomacea diffusa, also known as the spike topped apple snail, from the #Mumbai region, as part of our ongoing studies on #urbanwildlife, and the #ecology of introduced species, in #India, Mumbai.
The study was officially published in the 'ELA Journal of Forestry and Wildlife' - a peer reviewed #science journal, which is also the official journal of the #Maharashtra State #Forest Department.

Link to paper:…

#sciencetwitter #TwitterNatureCommunity
Spiked Topped Apple Snails in #Mumbai (and other parts of #India) are the direct result of the #aquarium trade - either as accidental, or deliberate releases from home aquaria.

In the #LongFoodMovement report, we're reminded that the world’s 30 million artisanal #fishers and workers provide nearly half of the #fish we eat (@IPBES, 2019).

But with #climatechange & island/ocean grabbing, small-scale fishers & their communities are in peril.

🧵Thread 👇🏾
Island/#ocean grabbing is likely to intensify as countries seek to solidify their influence, their #food supply chains, & their global sourcing and distribution networks. For example, in the #RedSea region, conflicts over fish & other marine resources threaten rich #biodiversity.
Meanwhile, in the South China Sea, said to
have some of the highest marine #biodiversity on earth, #China has been building airstrips, ports & other facilities on disputed islands & reefs, w/ the apparent aim of establishing military bases (cf. Ives,

1/6 #UEACEEC21 #Sesh1
Salmon usually return to their natal streams to spawn, presenting a risk of breeding between close genetic relatives.
By reducing heterozygosity, #inbreeding can deplete the genetic variability of a population, affecting offspring fitness and survival Image
2/6 #UEACEEC21 #Sesh1
However, #salmons are externally fertilisers and females are polyandrous. So how do females control #fertilisation when this occurs outside of their bodies?
Can they somehow hamper fertilisation from their siblings?#evolution may have allowed such mechanisms Image
3/6 #UEACEEC21 #Sesh1
To test this, we analysed #spermmotility in sibling vs non-sibling ovarian fluid, a substance released with eggs and involved in #sexualselection in #fish. Then, we compared #fertility & hatch rates between sib vs non-sib crosses after #invitro fertilisation Image

After 5 years of #Brexit #Fish, everyone knows?

1. EU buys our fish
2. Tariffs kill margins
3. Perishable fish hate delays

On Sunday Fishy Minister, George Useless said tariffs didn't matter, but surely even he didn't mean fish?

Yeah. He's a Pillock.⏬…
Why the fuss about his plans?

He (Maybe) gives us additional fishing areas. But

1. Kills EU fish trade due to
2. Tarrifs on fish
3. Perishable fish rotting in kent.

Recognise anything?

We knew they were in denial, but this is just insulting the intelligence of the industry.
This is the full letter from the industry to Mr Useless about how dangerous and useless are his #Brexit plans

Fish is the most emotive Brexit issue
Its effect on a deal is many times its value

If these cretins understood anything surely, it'd be FISH

Nope Pillocks on Pollock

[1] Reports indicate that the #Venezuelan Floating Storage/Production Vessel, FSO #nabarima, currently located in the #gulfofparia, has approximately 1.2 million barrels of crude oil onboard & the vessel is in distress.

Why is this of concern to #TrinidadandTobago?
[2] The #gulfofparia is a semi-enclosed body of water located between #Trinidad and #Venezuela. The #marine #environment is a very dynamic system. Any oil that is spilled in the #gulfofparia will likely be transported by the currents and reach the shores of both countries.
[3] Presently, the #gulfofparia supports important #fisheries 🐟🦐 Many #fisherfolk in #Trinidad harvest #fish and #shellfish from the #gulfofparia🛥️ The livelihood of these #fisherfolk are dependent on a healthy marine environment.

A recent study in @nature couldn't replicate drastic CO2 effects on coral reef #fish behaviour & empirically found no effect of #oceanacidification

Our #metaanalysis of the past decade on this topic concurs

We demonstrate one of the most striking examples of the #DeclineEffect in #ecology to date, w/ reported effects of OA on fish behaviour all but disappearing over past decade

If you’ve never heard of the #DeclineEffect see:
Qualitatively the number of studies reporting “strong” effects of #oceanacidification on fish behaviour have plummeted over time

1/10: So, it’s four years since the #Brexit referendum. We have formally left the #EU but remain in the single market & customs union until 31 December. The future relationship beyond that is still unknown. What are the chances of a deal before the deadline? A thread...
2/10: Negotiators have just 4 months left. It will take two more after that for a deal to be ratified. If there is a deal the scope will be narrow; aiming for tariff-free & quota-free trade in goods. Little on services, never mind non-trade issues. A hard version of #Brexit.
3/10: UK insists a deal must not limit “sovereignty” or leave jurisdiction with the ECJ. It has proposed a series of deals built around a free trade agreement that would involve widespread removal of traditional trade barriers, but far short of the promised “frictionless trade”.

Some talks I liked at #ASGCT20 today:
Sean Wang from Cepko lab applied SABER #FISH to (…) #AAV genomes, tracking individual particles w high time res. I wonder if pH sensitive probes would allow imaging of intracellular trafficking...
Faith Conroy at #UMass targeting Htt with siRNAs, and used intentional mismatches to improve specificity for SNP gene product over WT.
Beautiful Outstanding Achievement talk by Mavis Agbandje-McKenna. Lots of #AAV structure, and work with @asokan_duke and others to map out functional #AAV surface host interactions. Also work on non-#primate #AAVs, which could evade human neutralizing antibodies.

1. #WSTC6 #FishSesh Purse seine fishing is an emerging arena for seabird #bycatch. However, these are also impacting seabirds with edible #fish oil. #Soaked individuals are disrupted in waterproofing, thermal isolation, flight, and prone to #death. How does this happen? Image
2. #WSTC6 #FishSesh #Chile #shearwaters #albatrosses #gulls are affected by fish oil from the direct discharge of #wastewaters or individuals #trapped in the purse seine gear (mean N°ind./set 8.41-12.90 CI 95%, with 96.87% of all trapped soaked) Image
3. #WSTC6 #FishSesh Feathers showed disruption of micro-structures (barbules) under responding at low oil concentrations (5%). Onboard, soaked seabirds remain under this status after 24h of oil exposure when trapped in fishing gear Image

Yesterday, on the 1st day of the UK's #COVID19 lockdown, I started posting a daily #deepsea fact on my instagram (@diva_amon) to help amaze/excite/distract. Will cross-post them here also. Feel free to add comments/questions/etc. & I'll try to get to them #DivasDailyDeepSeaFact
DAY 1: The test used to diagnose #COVID19 & other pandemics was developed with the help of an enzyme isolated from a #microbe found in #DeepSea #HydrothermalVents & freshwater hot springs.
Video: @NERCscience @adrg1.
Fact: @WHOI.
DAY 2: #DeepSea life can be slow. Case in point: the Greenland #shark (Somniosus microcephalus) can live for >400 years & only becomes sexually mature at >150 years old. Yes, it took me a grand total of 2 posts to start talking about sex. I blame @Marahh2o. Video: @oceanexplorer
