Red tide at night, red tide at night. Wo oh, wo oh oh oh oh oh oh oh. Bioluminescent tide at La Jolla Cove under a crescent moon. 2. by slworking2

I shot this on Monday night (10/4/2011) at La Jolla Cove.

We’ve got a pretty spectacular red tide going in the waters off San Diego (and farther north and south). The organism is Lingulodinium polyedrum, my favorite dinoflagellate. Why favorite? Because it’s intensely bioluminescent. When jostled, each organism will give off a flash of blue light created by a chemical reaction within the cell. When billions and billions of cells are jostled – say, by a breaking wave – you get a seriously spectacular flash of light.

So please take the opportunity to go down to the beach tonight or tomorrow night to see one of nature’s most impressive light shows.

it was late in the evening | davenport, california by elmofoto

Went shooting with a pretty cool group of folks the weekend before last. The day started in a redwood forest and ended at the beach in Davenport. I can’t encourage people enough to go on photowalks – they’re such a great way to learn from others AND meet some great people who share your passion for photography. Try it!

SURFACE CURRENTS 61 Cape of Good Hope, they send a branch north, whichis probably attributable partly to the pull of thetrade winds, partly to a resistent current in theopposite direction coming from the Indian Ocean.This branch contributes to the cold Benguela Currentalong the West African coast, of which a large partseems due to an upwelling of cold water from below,owing to water being drawn off the surface by thetrade winds. This brings us back to our starting-pointin the South Equatorial Current. Between the Northand South Equatorial Currents is an ill-defined back-water, the Counter-Equatorial Current, with a sloweasterly trend. We may now turn to the PACIFIC OCEAN.

Blue ringed octopus – swimming toward the camera lens by Okinawa Nature Photography

It is always challenging photographing the blue ringed octopus swimming. The autofocus system always has trouble at night picking up on this micro octopus

The blue rings become intense when aggrevated. Extremely venomous, can be fatal to humans!

Acontinental island is one which, from the nature of itsrocks, or more generally from the considerable varietyof the animals and plants which live upon it, mustbe supposed to have been at one time connected withsome continental mass of land, upon the surface ofwhich, according to our present views, a large varietyof animals and plants may be supposed to have beenevolved. Thus, for example, all the greater islandsof the East and West Indies must have been connectedat one time with their neighbouring continents. ISLANDS 83 There is little room for doubting (see Fig. 21) thatMadagascar was at one time joined to Africa, and NewZealand to Asia and Australia through New Guinea ;New Zealand may have had also a polar connectionwith South America. The Seychelles Islands areformed of granite, a type of rock essentially associatedwith the immense early solidifications of eruptionswhich formed great continents. They doubtless were apart of the Indo-African Continent, which is believed

CHART VIII.— AREAS OF MARINE DISTRIBUTION. The areas here adopted for the purposes of the Challenger Societys Bibliography of Marine Faunas are based on what appears to be the natural boundaries of temperaturecurrent, depth, etc., which affect the distribution of both floating and bottom animals. [Between pp. 256, 257. VARIOUS 251 forms often encrust stones in large sheets. They arestrangely degenerate animals, for they begin life as free-swimming, tadpole-like larvae, which approach some-what to the Vertebrates in their structure.

Fig. 178.— Amphi-nome, a Bristle-Worm (Blake), 252 ANIMALS OF THE SEA FLOOR As regards the geographical distribution of theanimals inhabiting moderate depths, it may be said,speaking very generally, that the character of the faunais determined rather by temperature than by geogra-phical position. Thus it is found that genera andeven species of animals, which may be dredged at adepth of a few fathoms in the Arctic regions, occur atgreater depths in the more southern parts of theirrange, where the shallow water is too warm for them.For example, a certain starfish which is found com-monly off the west coast of Ireland between 300 and400 fathoms, and which stretches as far south as theBay of Biscay in deep water, occurs at a depth of15 fathoms within the Arctic circle.

Of the group to which oysters, snails, and cuttle-fishbelong, the Mollusea,some subdivisions occur in Plankton. The oyster-forms, or Lamellibranchs, possessing twoshells, are occasionally represented by larvae (Fig. 134).The snail-forms, or Gastropoda, are frequently met.Janthina, a warm-water snail, sometimes thrown onour western shores, has a purple shell; to its foot isattached a raft, on the underside of which the eggs areembedded. Atlanta (Fig. 131) has a spiral shell, with anarrow keel; Carinaria, like a transparent slug, carriesa shell on its hump (Fig. 132); very like it, but withoutshell or hump, are several other warm-water forms.The pteropod, or wing-footed forms, are found in allseas ; of these the majority have shells (Figs. 133,135).Near-shore larvae of Gastropods are often plentiful;the most characteristic is the Veliger stage (Fig. 136).

In most species thesmall body scarcely affords room for the attachmentof eight (very rarely ten) long slender legs, but in afew cases the legs are short and stout; as, for instance,in the common Pycnogonum littorale, which, in spiteof its name, is often found in moderately deep water.Most of the Pycnogons are of small or moderate size,but in some deep-water species the legs may span alength of 2 feet.

Fig. 174.—Archaster, a Star-Fish (Blake). The commoner forms of the Mollusca, at any rate ofthe shelled species, are familiar to everyone, but thereare some shell-less species, and others with peculiarshells, which call for special note. The usual type ofGastropod, as exemplified by the whelk or periwinkle,bears an asymmetrically coiled shell, but there is reasonto believe that the earliest forms of molluscs weresymmetrical. This symmetry is still found in theChitons, in which the shell is made up of eight plates, 248 ANIMALS OF THE SEA FLOOR overlapping as in an armadillo or wood-louse (Fig. 184).Allied to the Chitons is a very remarkable group ofmolluscs, in which the shell is entirely absent. Theseare for the most part wormlike in form, and are usuallyfound tightly coiled round the branches of Hydroidsand Alcyonarians. The nudibranchs, or sea-slugs, are shell-less gastro-pods, which externally appear to be symmetrical.They start life, however, in a minute coiled shell. Onesection
