[7] [8] The colossal squid has the largest eyes of any known creature ever to exist, with an estimated diameter of 27–30 cm (11–12 in) [9] to 40 cm (16 in) for the largest collected specimen. The species has similar anatomy to other members of its family, although it is the only member of Cranchiidae to display hooks on its arms, suckers ...
A form of flowering plant that far exceeds Pando as the largest organism on Earth in area and potentially also mass, is the giant marine plant, Posidonia australis, living in Shark Bay, Australia. Its length is about 180 km (112 mi) and it covers an area of 200 km 2 (77 sq mi).
A 7 m (23 ft) giant squid, the second largest of all invertebrates, encased in ice in the Melbourne Aquarium. Both the largest mollusks and the largest of all invertebrates (in terms of mass) are the largest squids. The colossal squid (Mesonychoteuthis hamiltoni) is projected to be the largest invertebrate.

The heaviest known cephalopod, and the largest living invertebrate, is the colossal squid. The largest recorded specimen of this species, caught in the Ross Sea in 2007, weighed 495 kg (1,091 lb). However, its beak is not the largest known from this species; even bigger colossal squid beaks have been recovered from the stomachs of sperm whales ...
Despite being the largest invertebrate known to man, the giant squid remains elusive to scientists and researchers. Their deep sea territory has made them especially hard for experts to study and ...
Invertebrates cells fire in response to similar stimuli as mammals, such as tissue trauma, high temperature, or changes in pH. The first invertebrate in which a neuron cell was identified was the medicinal leech, Hirudo medicinalis. [14] [15] Learning and memory using nociceptors in the sea hare, Aplysia has been described.
The Tasmanian giant freshwater crayfish (Astacopsis gouldi), also called Tasmanian giant freshwater lobster, is the largest freshwater invertebrate and the largest freshwater crayfish species in the world. The species is only found in the rivers below 400 metres (1,300 ft) above sea level in northern Tasmania, an island-state of Australia.
