Hi all

We have a winner and that winner is...Restio :clap: :clap:
The stonefish is correct. The stone fish is actually reguarded as the most poisonous fish in the world. Their dorsel spines are exceptionally tough and when stood act like hypodermic needles injecting a highly toxic substance into the unlucky victim which is excrutiatingly painful and potentially fatal. One of the ways to treat a wound from a stonefish is to immediatly immerse it in hot water for at leat 30 minutes as this will destroy the poison.

On to you Restio

Thanks, naturelover!

I am part of the phylum Mollusca, and some scientists think that I and other members of my class are the most highly developed of all invertebrates.

I am the giant chameleon of the depths and can grow to length of 3m and reach a maximum weight of 25 kg.

Octopus is halfway there! :clap: But that's not the right species of octopus.

The common octopus, O vulgaris is much smaller (maximum length 1.5m, maximum weight 6 kg). The one I'm thinking of is a giant cephalopod.

The common octopus is also a near-shore species, whereas this magnificent species lives further out to sea (hence my clue: of the depths) and is regularly caught by bottom trawlers on the south coast.

Hmm, I see what you mean, jfthibeau. I was thinking of Octopus magnificus. My information was from a fact sheet I found on the website of the Two Oceans Aquarium, and it looked pretty well researched, with references etc.

I think I'll give it to jfthibeau for being first with Octopus!

... again thanks Restio, Naturelover ... and ZZ .. :D
I'm very confused to trust the awards :redface: ...

... The third one that I propose today to the pannel of experts is this one : 8)

Clue 1) The sex of my babies are determined by the average temperature during the incubation period (in the middle third).
This period is 3 months.

... let's go .... :D

:lol: ...

:clap: :clap: ... too easy .... :cry: ....

.. explanation .... 8)

Nile crocodiles have Temperature-dependent sex determination which means the sex of their hatchlings is determined not by genetics, but by the average temperature during the middle third of their incubation period. If the temperature inside the nest is below 31.7 °C (89.1 °F), or above 34.5 °C (94.1 °F), the offspring will be female. Males can only be born if the temperature is within that narrow 5-degree range.




Croc is a good answer ... but Nile Crocodile is much better ... :lol:
.. so ... I do'nt know who wins the next one ... :lol:

Jose , you are the first ...thus, it's for you ... but if you want, the place is also open for NatureLover ... :lol:
