The Speech! allophone-based speech synthesizer software for the BBC Micro was tweaked to pronounce ghoti as fish. [13] Examination of the code reveals the string GHOTI used to identify the special case. In the Yu-Gi-Oh! Trading Card Game, there is a series of fish-type cards called "Ghoti". [14]
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 have been described in the sea hare, Aplysia.
Coelacanths also retain an oil-filled notochord, a hollow, pressurized tube which is replaced by a vertebral column early in embryonic development in most other vertebrates. [36] The coelacanth's heart is shaped differently from that of most modern fish, with its chambers arranged in a straight tube.
The crocodile icefish or white-blooded fish comprise a family (Channichthyidae) of notothenioid fish found in the Southern Ocean around Antarctica. They are the only known vertebrates to lack hemoglobin in their blood as adults. [ 2 ]
Pacific sea nettles, Chrysaora fuscescens. Cnidaria (/ n ɪ ˈ d ɛər i ə, n aɪ-/ nih-DAIR-ee-ə, NY-) [4] is a phylum under kingdom Animalia containing over 11,000 species [5] of aquatic invertebrates found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.
Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. [4] Juveniles of some representatives of the genera Bodianus , Epibulus , Cirrhilabrus , Oxycheilinus , and Paracheilinus hide among the tentacles of the free-living mushroom corals and Heliofungia actiniformis .
This is a list of invertebrates, animals without a backbone, that are commonly kept in freshwater aquaria by hobby aquarists. Numerous shrimp species of various kinds, crayfish, a number of freshwater snail species, and at least one freshwater clam species are found in freshwater aquaria or '0' salinity water body.
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (/ k r ə ˈ s t eɪ ʃ ə /), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill ...
