Asterias is a genus of the Asteriidae family of sea stars. It includes several of the best-known species of sea stars, including the (Atlantic) common starfish, Asterias rubens, and the northern Pacific seastar, Asterias amurensis. The genus contains a total of eight species in all. All species have five arms and are native to shallow oceanic areas of cold to temperate parts of the Holarctic. These starfish have planktonic larvae. Asterias amurensis is an invasive species in Australia and can in some years become a pest in the Japanese mariculture industry.

Cratena is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Facelinidae.
Gorgoniidae is a family of soft corals, a member of the subclass Octocorallia in the phylum Cnidaria. Nearly all the genera and species are native to the east and west coasts of America.
Abatus cordatus is a species of sea urchin in the family Schizasteridae. It is native to shallow seas surrounding certain island groups in the southern Indian Ocean. The body is protected by a hard test or shell which is covered with spines. The female broods its young in deep pockets on the upper surface, retaining the young in place with specialised spines. American zoologist Addison Emery Verrill first scientifically described A. cordatus in 1876.
Evasterias troschelii is a species of starfish in the family Asteriidae. Its common names include the mottled star, false ochre sea star and Troschel's true star. It is found in Kamchatka and the north western coast of North America.
Leptogorgia is a genus of soft coral in the family Gorgoniidae. The genus has a widespread distribution with members being found in the eastern Atlantic Ocean from Western Europe to South Africa, the Mediterranean Sea, the Atlantic coasts of North and South America, the Antilles and the Pacific coast of America. Species are found in both shallow and deep waters.
Leptogorgia hebes, commonly known as the regal sea fan or false sea fan, is a species of soft coral in the family Gorgoniidae. It was formerly included in the genus Lophogorgia but that genus has been dismantled.
Antillogorgia bipinnata, the bipinnate sea plume, is a species of colonial soft coral, a sea fan in the family Gorgoniidae. It is found in the Caribbean Sea. It was first described as Pseudopterogorgia bipinnata in 1864 by the American zoologist Addison Emery Verrill. Williams and Chen (2012), transferred all the Atlantic species of Pseudopterogorgia to Antillogorgia.
Calcinus verrillii, commonly known as Verrill's hermit crab, is a species of hermit crab in the genus Calcinus which is endemic to Bermuda. It was first described by the American zoologist Mary J. Rathbun and named in honour of the American zoologist Addison Emery Verrill, who spent much time with his students studying the geology and marine fauna of Bermuda.
Acropora paniculata is a species of acroporid coral that was first described by Addison Emery Verrill in 1902. Found in marine, tropical, shallow reefs on the upper slopes, it occurs at depths of between 10 and 35 m. It is classed as a vulnerable species on the IUCN Red List, and it has a decreasing population. It is uncommon but found over a large area, including in five regions of Indonesia, and is classified under CITES Appendix II.
Cuspidaria is a genus of bivalves in the family Cuspidariidae.
Mediaster is a genus of starfish in the family Goniasteridae. It was circumscribed in 1857 by William Stimpson for M. aequalis, the genus's type species. Its junior synonym is the genus Isaster, which was circumscribed in 1894 by Addison Emery Verrill for the species now known as M. bairdi. Verrill himself synonymized the two genus names in 1899.
Grimpoteuthis megaptera is a species of umbrella octopus known from five specimens, collected by Addison Emery Verrill. Between two and three of these specimens may belong to different species.
