Evechinus Chloroticus
Kina (''Evechinus chloroticus'') is a sea urchin endemic to New Zealand. This echinoderm belongs to the family Echinometridae and it can reach a maximum diameter of 16–17 cm. Kina have been a traditional component of Māori diet since pre-European times and has been fished commercially since 1986 in small quantities under the quota management system in restricted areas along the coast of New Zealand. Attempts to export ''E. chloroticus'' to Asian markets have been unsuccessful, so it may not be an economically attractive species for aquaculture development (James 2010). ''Evechinus chloroticus'' is distributed throughout New Zealand and in some northern and southern offshore islands. Habitat This sea urchin is found all around New Zealand in shallow waters around 12–14 metres deep, although there are also intertidal populations in the north of both the North and South Islands. ''Evechinus chloroticus'' prefers areas with moderate wave action. In the north of New Zeal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echinometra Lucunter
''Echinometra lucunter'', the rock boring urchin, is a species of sea urchin in the family Echinometridae. It is found in very shallow parts of the western Atlantic Ocean and the Caribbean Sea. Description ''Echinometra lucunter'' has an elliptical rather than a round test (shell). It can grow to a diameter of about and grows larger at the extreme north and south ends of its range than it does in the centre. It has moderately short spines with wide bases and sharp tips. The colour of the test varies from black to deep brownish-red, often being more ruddy on its aboral (upper) surface than on its oral (lower) surface. The spines are usually black. Distribution and habitat ''Echinometra lucunter'' is common throughout the Caribbean Sea and also occurs in Florida, Bermuda and the South American coast as far south as Brazil. It occurs on shallow rocky areas and on coral reefs usually at depths of or less but occasionally in deeper water down to about . It is sometimes found am ...

Colobocentrotus Atratus
''Colobocentrotus atratus'', the helmet urchin or shingle urchin, is a species of sea urchin in the family Echinometridae. In Hawaii it is known as "hāʻukeʻuke." It is found on wave-swept intertidal shores in the Indo-West Pacific, particularly on the shores of Hawaii. Description This urchin is a deep maroon colour and shaped like a domed limpet. It can grow to the size of a softball, but is usually much smaller. The upper surface is a mosaic of tiny polygonal plates formed from modified spines to form a smooth mosaic. This is fringed by a ring of large, flattened modified spines. On the underside there is another ring of smaller flattened spines and a large number of tube feet. Biology This urchin is usually found on substrates fully exposed to waves and their associated abrasive effect, often in groups. It feeds on periwinkles, other urchins and coralline algae Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard ...

Heterocentrotus
''Heterocentrotus'' is a genus of slate pencil urchins, part of the familia Echinometridae. They are mainly found in the Indo-Pacific basin, especially in Reunion or Hawaii. This genus appeared in the Miocene and spread throughout the warm Indo-Pacific. Description ''Heterocentrotus'' are brightly colored tropical sea urchins with very thick spines that have given them the nickname "pencil urchins". The genus consists of sea urchins with rounded (but slightly elliptical) test, with the peristome (mouth) located in the center of the oral surface (lower) and the periproct at opposite, at the apex of the aboral (upper) face. The apical disc is dicyclic, with a reduced periproct. The peristome is also reduced and elliptical, with limited mouth notches. The ambulacrum Ambulacrum is an architectural word that denotes an atrium, courtyard, or parvise in front of a basilica or church that is surrounded by arcades or colonnades, or trees, and which often contains a fountain ...
