Tima is a genus of hydrozoans in the family Eirenidae.

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Hydrozoa class of cnidarians

Hydrozoa are a taxonomic class of individually very small, predatory animals, some solitary and some colonial, most living in salt water. The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony. A few genera within this class live in fresh water. Hydrozoans are related to jellyfish and corals and belong to the phylum Cnidaria.

Family is one of the eight major hierarcical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Species

The genus contains the following species: [1]

<i>Tima formosa</i> species of cnidarian

Tima formosa is a colonial species of marine hydrozoan in the family Eirenidae. They live in northern parts of the Atlantic Ocean, in the upper epipelagic zone.

Pyrophorus is a genus of click beetle. They are one of several genera in the tribe Pyrophorini, all of which are bioluminescent. Their bioluminescence is similar to that of another group of beetles, the fireflies, although click beetles do not flash, but remain constantly glowing. They have two luminescent spots at the posterior corners of the pronotum, and another brighter spot in the dorsal region of the abdomen. This spot is even brighter and can only be seen when in flight. Bioluminescent click beetles are found throughout tropical and subtropical America. Species from Texas, Florida, and Cuba are now in different genera in the tribe Pyrophorini, such as Deilelater.

The pouches do not extend below the points of origin of the primary tentacles. Members of some genera have a peripheral canal system and others do not. No radial canals or secondary tentacles are present.
