Hydrozoan Life Cycle
Ectopleura crocea is a common hydroid in the Atlantic, usually abundant on artificial substrates. They form dense tufs with hundreds of individuals, which hydrocaulli are up to 10-12 cm long. The species doesn't have a medusa in its life cycle, and gametes are produced within structures called gonophores, which stay fixed to the polyp body. Individuals are either male or female. Spermatozoa are released into the water from male gonophores, fertilizing the eggs that remain within female gonophores. Embryos develop inside female gonophores into actinula larvae, the dispersive stage of the species. A mature female polyp releases hundreds of actinulae. As you may see in the video, the actinula struggles to get free from the gonophore. It pushes several times using its tentacles; it succeeds in liberating one tentacle at a time, until it finally got out through the aperture of the gonophore. It took about 2 hours for the actinula shown in the video to get free, but this period may vary a lot. The actinula settles by its aboral end and elongates to form a juvenile polyp. It may settle on the perisarc of adults, as is seen in the video. Newly released actinulae have aboral tentacles and rudiments of oral tentacles.

Ectopleura obypa (Hydrozoa, Cnidaria) foi descrita por Migotto & Marques (1999) a partir de espécimes encontrados em São Sebastião, SP. A maioria das colônias, que crescem sobre uma variedade de substratos artificiais, como bóias e cabos de náilon, são especialmente notáveis por sua cor verde-limão. Contudo, algumas -- como as apresentadas no vídeo -- são menos chamativas e apresentam uma cor rosa pálida.
As colônias atingem até 35 mm de altura, formando tufos com muitos hidrantes, cujos hidrocaules são unidos por estolões ramificados. Os hidrocaules são tubulares e se expandem gradual e ligeiramente da base ao ápice; são revestidos por um perissarco liso, sem anelações, de cor marrom clara. A região do pescoço é muito flexível e mais clara que o restante do hidrocaule, sendo recoberta por um perissarco fino e elástico, possibilitando ao hidrante movimentar-se para todos os lados. O hidrante possui uma coroa de 16 a 30 tentáculos aborais filiformes, com nematocistos concentrados ao longo da superfície adoral (interna). Os tentáculos orais são curtos e parcialmente aderidos à parede do hipostômio; os nematocistos se concentram uma dilatação terminal e em 1 a 3 dilatações menores localizadas na superfície interna. Os brotos de medusa se formam logo acima dos tentáculos aborais. As medusas recém liberadas têm cerca de 0,4-0,7 mm de diâmetro, possuem 4 bulbos marginais, dois dos quais com tentáculos opostos. Na exumbrela existem 8 fileiras meridionais de nematocistos. Os tentáculos têm uma dilatação esférica na extremidade distal, e 1-3 dilatações menores. As medusas começam a pulsar horas antes da liberação.
O vídeo foi realizado no Centro de Biologia Marinha da Universidade de São Paulo, em São Sebastião, SP (CEBIMar-USP) (www.usp.br/cbm). As colônias foram filmadas sob estereomicroscópio.

Hydrozoa
Hydrozoa (hydrozoans, from ancient Greek ὕδρα, hydra, "sea serpent" and ζῷον, zoon, "animal") 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.
Some examples of hydrozoans are the freshwater jelly (Craspedacusta sowerbyi), freshwater polyps (Hydra), Obelia, Portuguese man o' war (Physalia physalis), chondrophores (Porpitidae), "air fern" (Sertularia argentea), and pink-hearted hydroids (Tubularia).
Anatomy
Most hydrozoan species include both a polypoid and a medusoid stage in their lifecycles, although a number of them have only one or the other. For example, Hydra has no medusoid stage, while Liriope lacks the hydroid stage.
Polyps
The hydroid form is usually colonial, with multiple polyps connected by tubelike hydrocauli. The hollow cavity in the middle of the polyp extends into the associated hydrocaulus, so that all the individuals of the colony are intimately connected. Where the hydrocaulus runs along the substrate, it form a horizontal root-like stolon that anchors the colony to the bottom.

Tubular hydroid
The tubular hydroid (Ectopleura crocea) is a species of hydroid cnidarian, and is found in temperate coastal waters. It is a member of the family Tubulariidae.
Description
The tubular hydroid resembles a long-stemmed narrow-petalled flower. The stem is encased in a sheath. The polyps are pink or orange and white, with an outer ring of long tentacles. There are short tentacles surrounding the mouth rising from a cluster of yellow bead-like bunches of reproductive sporosacs.
Distribution
This species is native to the Atlantic coast of North America, and also occurs in the Mediterranean Sea, the northeastern Atlantic Ocean, South Africa, Australia, New Zealand, and the west coast of North America.
Ecology
Male and female sporosacs are on separate hydranths (feeding individuals) in the colony. These animals feed on tiny planktonic crustaceans.

Ectopleura obypa (Hydrozoa, Cnidaria) foi descrita por Migotto & Marques (1999) a partir de espécimes encontrados em São Sebastião, SP. A maioria das colônias, que crescem sobre uma variedade de substratos artificiais, como bóias e cabos de náilon, são especialmente notáveis por sua cor verde-limão. Contudo, algumas -- como as apresentadas no vídeo -- são menos chamativas e apresentam uma cor rosa pálida.
As colônias atingem até 35 mm de altura, formando tufos com muitos hidrantes, cujos hidrocaules são unidos por estolões ramificados. Os hidrocaules são tubulares e se expandem gradual e ligeiramente da base ao ápice; são revestidos por um perissarco liso, sem anelações, de cor marrom clara. A região do pescoço é muito flexível e mais clara que o restante do hidrocaule, sendo recoberta por um perissarco fino e elástico, possibilitando ao hidrante movimentar-se para todos os lados. O hidrante possui uma coroa de 16 a 30 tentáculos aborais filiformes, com nematocistos concentrados ao longo da superfície adoral (interna). Os tentáculos orais são curtos e parcialmente aderidos à parede do hipostômio; os nematocistos se concentram uma dilatação terminal e em 1 a 3 dilatações menores localizadas na superfície interna. Os brotos de medusa se formam logo acima dos tentáculos aborais. As medusas recém liberadas têm cerca de 0,4-0,7 mm de diâmetro, possuem 4 bulbos marginais, dois dos quais com tentáculos opostos. Na exumbrela existem 8 fileiras meridionais de nematocistos. Os tentáculos têm uma dilatação esférica na extremidade distal, e 1-3 dilatações menores. As medusas começam a pulsar horas antes da liberação.
O vídeo foi realizado no Centro de Biologia Marinha da Universidade de São Paulo, em São Sebastião, SP (CEBIMar-USP) (www.usp.br/cbm). As colônias foram filmadas sob estereomicroscópio.

Ectopleura obypa (Hydrozoa, Cnidaria) foi descrita por Migotto & Marques (1999) a partir de espécimes encontrados em São Sebastião, SP. A maioria das colônias, que crescem sobre uma variedade de substratos artificiais, como bóias e cabos de náilon, são especialmente notáveis por sua cor verde-limão. Contudo, algumas -- como as apresentadas no vídeo -- são menos chamativas e apresentam uma cor rosa pálida.

Mr. Big Baboon
A great bear in the woods
He wants all he sees
From the snakes in the grass
To the chimpanzees
We all know it ain't fair
Well, it's a jungle out there
So go, bang your drum
Mr. Big Baboon
What monkey see
Monkey will do
Boom, boom, boom, boom
Mr. Big Baboon
Mad dog on the prowl
Sees the bear in the trees
They can never be friends
They're natural enemies
So you better beware
Well, it's a jungle out there
So go, bang your drum
Mr. Big Baboon
What monkey see
Monkey will do
Boom, boom, boom, boom
Mr. Big Baboon
Mr. Big Baboon
Sees the dog and the bear
It's a three way tie
It's a stalemate there
Facin' off eye to eye
Well, it's a jungle out there
So go, bang your drum
Mr. Big Baboon
What monkey see
Monkey will do
Boom, boom, boom, boom
Mr. Big Baboon
So go, bang your drum
Mr. Big Baboon
You can all join in
Monkey see monkey do
Boom, boom, boom, boom
