Laminaria digitata. Laminaria digitata is a tough, leathery, dark brown seaweed that grows to 2 or 3 metres (6 + 1 ⁄ 2 or 10 ft) long. The holdfast which anchors it to the rock is conical and has a number of spreading root-like protrusions called rhizoids.
Handling the newts does no harm, but ingestion of even a minute fragment of skin is deadly. In feeding trials, fish, frogs, reptiles, birds, and mammals were all found to be susceptible. [16] Mature adults of some salamander species have "nuptial" glandular tissue in their cloacae, at the base of their tails, on their heads or under their chins.
The white skin color of the olm retains the ability to produce melanin, and will gradually turn dark when exposed to light; in some cases the larvae are also colored. One population, the black olm, is always pigmented and dark brownish to blackish when adult. [17] The olm's pear-shaped head ends with a short, dorsoventrally flattened snout.
Gracilaria parvispora in a refugium, displaying dark coloration under high intensity lighting.. Gracilaria parvispora is composed of pointed, cylindrical branches, 1–4 mm (0.0–0.2 in) in diameter, extending from a central axis, 0.8–3.5 mm (0.0–0.1 in) in diameter, with a single holdfast.
The elkhorn sea moss varies in size, weight, and age. It is a dark greenish-brown hue and can sometimes be deep purple. The moss is cylindrical in shape throughout the seaweed. Its diameter averages 1.526 mm when dried. [1] Near the base of the seaweed, its average length is from 1 mm to 17 mm and 1 mm to 2 mm in diameter.
