Chordata

The trunk was supposed to branch into many different species, each species giving rise to many genera, and towards the top of the tree you would find so much diversity that you could distinguish separate phyla--the large divisions (sponges, mosses, mollusks, chordates, and so on) that comprise the kingdoms of animals, plants, and several others--take your pick.

They have been reported to parasitize acoels, platyhelminthes, annelids, molluscs, nemerteans, echinoderms, and chordates; and it has been suggested that they are present in the host animals as multinucleate plasmodia (Slyusarev and Miller, 1998).

In November 2017, we searched the literature systematically lo determine the frequency of leucism among classes of chordates. We first searched Web of Science for the terms leucistic, leucism., and partial albinism.

Some recognition and defense factors have been conserved through animal lineages, leading to the chordates, whereas others seem to be unique to invertebrates (Soderhall & Cerenius 1999).

Moreover, although highly abundant, only two records at the specific level of pelagic chordates were reported for the Caribbean of Costa Rica (Castellanos et al., 2009) until the present study.

Thirty-five food items were identified and grouped into six categories: algae, cnidarians, mollusks, arthropods, chordates and garbage/anthropogenic debris (Table 1, Fig.

The information of Brayophytes, trichaeophtes, chordates, vertibrates etc.

In general, the parasitic way of the life is successful and found in nearly every phylum of animals from protists to arthropods and chordates as well as in many plant groups.

Deuterostomes includes echinoderms (sea urchins and starfish) and chordates (creatures with a backbone).

Amphioxus or lancelet belongs to the subphylum Cephalochordata, an extant representative of the most basal chordates. Recently, we have found that amphioxus possesses a single GH-like hormone (GHl) gene encoding a functional protein capable of promoting growth [26].

There are acorn worms and before you start dismissing worms as inferior and primitive then consider that the acorn worms are classified with us humans in the Phylum Chordata -- chordates like us.
