Toxorhynchites
Toxorhynchites, also called elephant mosquito or mosquito eater, is a genus of diurnal and often relatively colorful mosquitoes, found worldwide between about 35° north and 35° south. It includes the largest known species of mosquito, at up to in length and in wingspan. It is among the many kinds of mosquito that do not consume blood. The adults subsist on carbohydrate-rich materials, such as honeydew, or saps and juices from damaged plants, refuse, fruit, and nectar.
Giant squid
The giant squid is the second-largest mollusc and one of the largest of all extant invertebrates. It is only exceeded by the colossal squid, "Mesonychoteuthis hamiltoni", which may have a mantle nearly twice as long. Several extinct cephalopods, such as the Cretaceous vampyromorphid "Tusoteuthis", the Cretaceous coleoid "Yezoteuthis", and the Ordovician nautiloid "Cameroceras" may have grown even larger.
