Temperate Invertebrates

Post by Brent on August 23rd 2010, 4:17 pm

We're looking for information on temperate invertebrates and their adaptations, feeding habits, appearance, etc. Also their general hardiness in captivity.

This is for AM on Nano-Reef, along with everyone reading his thread. Here's a link:

Thanks,

Brent

Lol temperate not coldwater! Coldwater refers to Arctic and Southern Ocean species.

... I never, ever use the term coldwater. Why the heck did I use it just then? Haha

I'll change it.

Perfect lol. So I'll just post my experiences on Pacific East Coast species.

Okay, well temperate crabs and snails thrive and seem to adjust well to captivity. Temperate crabs are often voracious eaters and are themselves subject to being meals for the many hungry predators of the temperate seas. Most snails thrive on algae in the tank and usually all forms. Certain species of snail such as the bubble shell seem to only eat certain forms of brown seaweed that is frequent in the wild but less so in captivity. Limpets and chitons seem to take a while to adjust to captive surroundings but once adjusted are very hardy.

I would add that crabs tend to reproduce quickly in captivity. I'm not sure of their behavior in the wild.

Just as well, sea slugs and nudibranchs should be in tanks large enough to support a healthy and stable population of their food source as most are specialized eaters. An example would be N. inermis which eats predominantly bubble shells and other smaller opisthobranchs.

Nice!

The 'in captivity' info was definately needed. I'll try my best at writing something on the species here, but really, I have no experience with keeping these inverts yet.

That would be nice since a lot of members on here are from the West Coast as opposed to the East or Gulf.

I'm at what I would call the border between arctic and temperate waters. Really, the only other place with about the same species is Europe.

I feel needed here. Razz

Go to some Euro forum! JK. I guess we could call where you are sub-arctic. Except that you have the gulf stream.

California Navanax profile here.

And in case you're to lazy to follow the link Razz.

California Navanax:
California Navanax (Navanax inermis)
Distribution - East Pacific, Gulf of California
Reef Compatible - With Caution
Diet - Carnivore
Minimum Tank Size - 30g
Max Size - 8"
Family - Aglajidae

Navanax inermis is a predatory headshield slug and member of the Aglajidae family, a group of vibrantly colored opisthobranchs who's species all retain a similarity in body shape. This species of sea slug secrets a sticky substance when threatened as do most opisthobranchs. They frequent rocky and sandy temperate regions and will feed on species of bubble shell and smaller sea slugs present to their location.

In the aquarium a stable food supply should be established as it is not well known of the California Navanax to take prepared foods. It's diet in the wild consists of bubble shells and smaller opisthobranchs. These mollusks should also form its diet in captivity.

The California Navanax (N. inermis) is distinguishable from the other species of Navanax inhabiting a similar range (N. polyalphos), by its size and color pattern. Navanax polyalphos is much smaller reaching only one inch in size and is black with white spots.

No. I figured we'd get a bit more info before announcing it.

Should I?

I got a start on that essay... I'm not really sure what else differentiates from the tropical world. Ideas are greatly, greatly appreciated... I'm still going to work on color form and find something to write about for a few specific families. Here:

Temperate invertebrates are very wide in variety. In fact, temperate ecosystems are just as sophisticated and diverse as their tropical cousins if not more so. In this essay we’ll talk about mobile invertebrates such as crabs, snails, and anemones.

There is a high percentage of predatory invertebrates in the temperate seas, relying primarily on zooplankton and other invertebrates for food. Ex: Crabs > Starfish > Whelks & predatory snails > bivalves > zoo & phytoplankton. This may be because of adaptations towards the larger amounts of plankton in the water. In saying this, there is still a huge population of herbivorous invertebrates in the temperate seas as well.

Go into how they are diverse. Explain more in depth the complexity of the temperate ecosystem. Basically in this article make the temperate sound like a huge rival in diversity and size to the tropical without letting it on that you are trying to make it sound better Sly.

Gahh I haven't added anything to that thread. Would love to add some info from here. I'm going to get back at it soon.

Hopefully I'll have some nice temperate info there soon!

Well maybe the fact that you joined the forum will be some incentive to get our lazy butts working on it!
