Blue Whale Catfish - Cetopsis coecutiens
Cetopsis coecutiens and C. candiru which achieve the largest body sizes within the Cetopsinae, are notorious for their voracious feeding habits; attacking not only carrion, but also live fishes in gill-nets (Barthem & Goulding, 1997: 44), and on occasion humans (Goulding, 1989: 185). The predatory and scavenging feeding habits of these species of Cetopsis perhaps contributed to the erroneous assumption that members of the Cetopsinae are “parasitic”; a conclusion that may have lead various previous researchers to align members of that subfamily with the species of the family Trichomycteridae, some members of which feed on the blood of their hosts. In contrast to the voracious feeding habits of Cetopsis candiru and C. coecutiens, all other members of the subfamily for which the diet is known prey primarily on allochthonous and aquatic insects.

Giant Water bug - Lethocerus Maximus
These insects are carnivores, and spend most of the time along the
sides of ponds and lakes awaiting prey. The larvae consume aquatic invertebrates that are small
in size, while adults feed on any small animals they can manipulate such as insects and also
water invertebrates. They also prey on vertebrates such as salamanders, tadpoles and even small
fish. This bug is able to grasp prey using the strong forelegs, and shove the sucking
mouthparts into the target. Adult bugs are able to capture larger prey through the use of their
clawed front feet and also the chemicals that are transferred into the body of the target organism.
The enzymes present cause the inside of the organism to turn into liquid, hence making it easy
for the bug to suck up.
