River Monsters – Season 4 Episode 9 – Lair of the Giants

It’s already the season finale of River Monsters; Season 4. The nice thing about the season finale is that it’s a 2 hour long special. Jeremy Wade will be fishing in the Essequibo River in Guyana, I would guess he’ll be fishing for Aimara or a large Catfish such as Piraiba Catfish. As usual we will be doing an episode recap after the show is complete. Check back at 11pm for our thoughts on the season finale of River Monsters, season 4.

After watching the intro it appears he is just going for an all around catch. Showing how many different Monster fish can live in one river. We’ll keep a list of what types of fish he lands in the Essequibo River. He is told of a large fish called a Lau Lau, I am assuming this will be a Arapaima Gigas, Piraiba Catfish or possibly a Red Tailed Catfish. He lands a Barbado Catfish (Pirinampus pirinampu) but nothing else, Jeremy is forced to travel even furthur up the Essequibo. A Payara (Hydrolycus scomberoides) takes his bait, a huge one. However while holding the Payara, his other rod takes off. It is a monster Red Tailed Catfish (Phractocephalus hemioliopterus), or as they call it in that region a Banana Catfish.

Jeremy lands yet another fish, this time a small Piraiba Catfish, his guide tells him this is the legendary Lau Lau. Just as I had assumed it would be, they can reach 9′ long and possibly 400+lbs. Jeremy then joins a researcher on a night time hunt for the rare (and protected) Black Caiman (Melanosuchus niger). They lasso an absolute Monster Black Caiman, 11′ long & 275lbs. (Update – We’ve added some video of the Caiman Capture, just click here.)

We are once again in a remote village where Jeremy will get help fishing for local monsters. He hand lines fishes with a local man who lands a Peacock bass (Cichla Temensis) with nothing but line and lure. Quite an impressive feat if you ask me. He finally gets into a boat and heads over to a turbulent area among some large rocks. Not moments after his bait hits the bottom does a fish grab it an run hard. He has something big, I wonder what it will be this time. A monster Jau Catfish (Zungaro zungaro), absolutely huge. I would guess around 80-90lbs.

Now we’re once again at a new location on the Essequibo, even deeper into the rainforest. Jeremy promises the locals he is camping with that he’ll catch dinner. He quickly lands a strange looking Pacu, he calls it a Pink Pacu. This looks like no other Pacu I’ve seen before. Once again the crew fishes for the evening meal, it looked like a Black Pacu that he caught but it wasn’t show close up, it could have been a Piranha as well.

After carrying their canoe through the forest the team runs across a huge Green Anaconda (Eunectes Murinus), Jeremy estimated it to be around 17′ long. So many monsters live in the Rainforest, I forgot to mention the hand sized Tarantula he saw earlier in this episode. They reach another falls and rapids, so once again they camp for the night and fish for dinner.  He lands something but it is huge, a Wolf Fish (Hoplias aimara). The final fish of the show will without a doubt be an Arapaima Gigas, as Jeremy fishes a Black Caiman heads over to investigate him while sitting in a small canoe. A bit unnerving I am sure, he splashed it using his paddle which seemed to work in scaring the Caiman away. He finally lands his monster, and as I suspected it’s an Arapaima Gigas. He takes a scale from the fish to test against the DNA of the Arapaima caught in the Amazon, to see if they are the same species or just cousins. Some say there are a few species of Arapaima as opposed to the single species designation of Arapaima Gigas, other names exist such as Arapaima Arapaima. (Preliminary tests show the Arapaima he caught could be a new species to Science) The season ends with Jeremy standing at the top of an amazing waterfall, one 5 times higher than Niagara Falls.

Arapaima Sp. (I would say Arapaima Gigas but it may be a new species)

  • Barbado Catfish (Pirinampus pirinampu) – Close to 10lbs, a very large specimen
  • Payara (Hydrolycus scomberoides) – Huge! 5lbs or so

  • Jau Catfish (Zungaro zungaro) – 80-90lbs
  • Pink Pacu (Sp. Unknown) – 3lbs

    Glad to see you in Guyana, Jeremy Wade. Beautiful country and fantastic river monsters.

  • Terry Ginis says:

    That was my favorite episode of season four-I’m headed to Guyana at the end of January myself to fish for a few “River Monsters”. I’ll also be on the Esscquibo and other remote rivers. This area is very unfished by outsides, so it will be interesting to see what monsters lurk there! I can’t wait to see where Jeremy will be in season five…more places to add to my “wish list”, I’m sure.

    Are you sure the arapaima is 6-8 feet long? I think it is a little smaller. It’s something like 5 feet.

  • Lena says:

    My husband is a huge fan of river monster. I’m so happy to see you went to my lovely country Guyana.

  • Joshua Baksh says:

    best episode, seeing Jeremy in my country catching our local monsters was awesome have to say not really quite a big sized Lau Lau/ Paraiba you caught compare to the monsters we got here that I’ve seen

  • mshare says:

    What is the music track at the very end of the episode where he is standing over the huge waterfalls? I must have that!!!!

    • TankTerrors says:

      I couldn’t tell you, I don’t know where you’d find that out at actually. I suppose the best chance would be to email Animal Planet and see if they can tell you.
