Mega Silurignath

Type: steel/electric

Ability: Rock Head 

Silurignath can mega evolve when holding a silurignathite.

Silurignath gets a much bigger mouth when it mega evolves in order to accommodate the several miniature mouths inside it. Every single tooth still crackles with electricity. This all means that the pokemon gets greater Attack and a sharp increase in Defence.

The pokemon’s skin also toughens, shown by how it now has the Rock Head ability, allowing it to safely make use of moves like Wild Charge and Double Edge without the recoil damage.

[I don’t even know what this is any more. it started off as a mix between a caecilian and a catfish but now it’s just ??? what is happening aah]


Mekong Giant Catfish (Pangasianodon gigas)

is a enormous species of shark catfish native to the Mekong basin of Southeast Asia. While physically this species looks similar to other catfish the size that this animal can obtain is amazing with individuals recorded growing up to 10 feet long. Making them the largest freshwater fish alive today. Despite their amazing size this species is critically endangered with most of their native range dammed, and over fishing taking a toll on their population size.

Looks harmless right? Mmm, maybe not. The candiru (Vandellia cirrhosa) is a tiny, parasitic catfish native to the waters of the Amazon and Oranoco Rivers in South America.

They have sharp bones with a series of spines located near the head which assist in feeding. With an appetite for blood, these fish will parasitize fish, mammals, and even humans! They’ve become infamous for a love for our urine.. Yep, if we’re skinny dipping and urinating in the body of water they lurk, they’ll come in through our anus and lodge themselves in our urinary tract- spines and all. If not removed in time (sometimes by amputation might I add), they’ll prove lethal to humans.

When locating fish, they’ll taste the water in search for a stream derived from the gills of a fish. They’ll then search for the fish itself, and lodge themselves in the gills. The spines will pierce the fish, drawing blood, while also anchoring the fish in place. 

They have few natural enemies, since they’re given a worse reputation than the pirhana. 


Zebra Pleco (Hypancistrus zebra)

…a small species of catfish that is endemic to Brazil where it is found in the Xingu River. Like other catfish zebra pleco are nocturnal and are often found in the bottom, where they feed on algae and small invertebrates. Zebra pleco are sexually dimorphic as males have a larger head and longer interopercular spines than females. Males will also guard the females eggs after they spawn.

 Although their conservation status is not evaluated zebra plecos face a serious threat due to the construction of the Belo Monte Dam, which could hinder the water flow of the Xingu river. Zebra pleco are highly sought after in the aquarium trade due to their unique coloration. However, their rarity makes them extremely expensive.

Royal Pleco (Panaque nigrolineatus)

…Also known as the Royal Panque, the royal pleco is a species of armored catfish (Loricariidae) that occurs in Brazil, Colombia, and Venezuela where it occurs in the Orinoco and Amazon river basins. Like other “plecos” Panaque nigrolineatus is a benthic feeder and feeds mainly on algae and detritus. P. nigrolineatus is widely known as one of the few fish that is capable of digesting wood, as (like termites) it has symbiotic bacteria in its gut, which are capable of breaking down the wood.

Malawi Squeaker (Synodontis njassae)

…a species of upside-down catfish (Mochokidae) which is endemic to Lake Malawi in Malawi, Mozambique and Tanzania. Malawi squeakers typically inhabit shallow areas among rocks and are omnivorous scavengers, feeding mainly on insects, crustaceans, molluscs, and other various invertebrates.

Hoplosternum littorale

…a species of armored catfish that occurs in all of South America east of the Andes and north of Buenos Aries. H. littorale typically inhabits swamps and is active at night. Its diet consists mainly of detritus and insects and micro-crustaceans. Like some other catfish H. littorale is capable of breathing both from its gills and intestines. Interestingly newly hatched larvae do not have this ability and are thought to absorb oxygen through their skin until the armored plates have developed.

Lophiosilurus alexandri

Also sometimes known as the “Pac-man Catfish” L. alexandri is a species of bumblebee catfish that is is known from the São Francisco River in Brazil. However, it has also been introduced into the Doce River basin as well. L. alexandri is unusual in that it has an extremely large mouth and flattened body. Which likely helps it blend into the substrate and ambush small fish.

L. alexandri is an excellent example of parallel evolution as it shares many morphological and life characteristics with the distantly related catfish of the genus Chaca.
